Failure to observe this warning may result in an electric shock or a fire. Wiring should be performed only by qualified personnel. Failure to observe this warning may result in an electric shock or a fire. When wiring the emergency stop circuit, check the wiring thoroughly before operation. Failure to observe this warning may result in injury. For the 400 V Class, make sure to ground the supply neutral. Failure to observe this warning may result in an electric shock or a fire. Verify that the Inverter rated voltage coincides with the AC power supply voltage. Failure to observe this caution may result in personal injury or a fire. Do not perform a withstand voltage test on the Inverter. Performing withstand voltage tests may damage semiconductor elements. Always tighten terminal screws of the main circuit and the control circuits. Failure to observe this caution may result in a malfunction, damage, or a fire. Never connect the AC main circuit power supply to output terminals U/T1, V/T2, W/T3, B1, B2, -, +1, or +2. The Inverter will be damaged and the guarantee will be voided. Do not connect or disconnect wires or connectors while power is applied to the circuits. Failure to observe this caution may result in injury. Do not perform signal checks during operation. The machine or the Inverter may be damaged. To store a constant with an Enter Command by communications, be sure to take measures for an emergency stop by using the external terminals. 4 Wiring Delayed response may cause injury or damage the machine. Wiring Instructions NOTE 1. Always connect the power supply for the main circuit inputs to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase power) via a molded-case circuit breaker (MCCB) or a fuse. Never connect the power supply to terminals U/T1, V/T2, W/T3, B1, B2, -, +1, or +2. The Inverter may be damaged. For single-phase Inverters, always use terminals R/L1 and S/L2. Never connect terminal T/L3. Fuses must be of ULclass RK5 fuse or an equivalent. Refer to page 231 for recommended peripheral devices.

For details, refer to Carrier Frequency Selection (n080)14kHz max on page 94. 3. Control wiring must be less than 50 m (164 ft) in length and must be separated from power wiring. Use shielded twisted-pair cable when inputting the frequency signal externally. 4. Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals. Additional insulation may be necessary in the end product to conform to CE requirements. 5. Closed-loop connectors should be used when wiring to the main circuit terminals. 29 6. Voltage drop should be considered when determining the wire size. Voltage drop can be calculated using the following equation: Phase-to-phase voltage drop (V) = 3 x Wire resistance (/km) x Wiring distance (m) x Current (A) x 10-3 Select a wire size so that voltage drop will be less than 2% of the normal rated voltage. 7. If the Inverter is connected to a power transformer exceeding 600 kVA, excessive peak current may flow into the input power supply circuit, and break the converter section. In this case, attach an AC reactor (optional) to the Inverter input side, or a DC reactor (optional) to the DC reactor connection terminal. Wire and Terminal Screw Sizes 1.

For 400-V Class Inverters, the voltage values (n012, n015, and n017) should be doubled. When running at a frequency exceeding 50/60 Hz, change the Maximum Output Frequency (n011). Note: Always set the maximum output frequency according to the motor characteristics. 1. For General-purpose Applications Motor Specification: 60 Hz Motor Specification: 50 Hz (Factory setting) 2.

Note: Constant n012 must be set to motor rated voltage. 57 Full-range Automatic Torque Boost (when V/f Mode is Selected: n002=0) The motor torque requirement changes according to load conditions. The full-range automatic torque boost adjusts the voltage of the V/f pattern according to requirements. The V7AZ automatically adjusts the voltage during constant-speed operation, as well as during acceleration. The required torque is calculated by the Inverter. This ensures tripless operation and energy-saving effects. Output voltage Torque Compensation Gain (n103) Required torque Operation V (Voltage) Required torque Increase voltage f (Frequency) Normally, no adjustment is necessary for the Torque Compensation Gain (n103, factory setting: 1.0). When the wiring distance between the Inverter and the motor is long, or when the motor generates vibration, change the automatic torque boost gain. In these cases, set the V/f pattern (n011 to n017). Adjustment of the Torque Compensation Time Constant (n104) and the Torque Compensation Iron Loss (n105) are normally not required. Adjust the torque compensation time constant under the following conditions: * Increase the setting if the motor generates vibration. * Reduce the setting if response is slow. 58 6 Programming Features Using Vector Control Mode Set the Control Mode Selection (n002) to use vector control mode. n002 = 0: V/f control mode (factory setting) 1: Vector control mode Precautions for Voltage Vector Control Application Vector control requires motor constants. The factory settings constants have been set at the factory prior to shipment. Therefore, when a motor designed for an Inverter is used or when a motor from any other manufacturer is driven, the required torque characteristics or speed control characteristics may not be maintained because the constants are not suitable. Set the following constants so that they match the required motor constants. Constant No. Name n106 Motor Rated Slip n107 Motor Line-toneutral Resistance n036 Motor Rated Current n110 Motor No-load Current Unit Setting Range Factory Setting 0.1 Hz 0.0 to 20.0 Hz * 0.001 (less than 10 ) 0.01 (10 or more) 0.000 to 65.50 * 0.1 A 0% to 150% of Inverter rated current * 1% 0% to 99% (100% = motor rated current) * * Setting depends on Inverter capacity. (Refer to pages 245 and 246.) Adjustment of the Torque Compensation Gain (n103) and the Torque Compensation Time Constant (n104) is normally not required. Adjust the torque compensation time constant under the following conditions: * Increase the setting if the motor generates vibration. * Reduce the setting if response is slow. Adjust the Slip Compensation Gain (n111) while driving the load so that the target speed is reached. Increase or decrease the setting in increments of 0.1. 59 * If the speed is less than the target value, increase the slip compensation gain. * If the speed is more than the target value, reduce the slip compensation gain. Adjustment of the Slip Compensation Time Constant (n112) is normally not required. Adjust it under the following conditions: * Reduce the setting if response is slow. * Increase the setting if speed is unstable.

To connect a reactor between the Inverter and the motor, set n108 to the sum of the initial value of n108 (Motor Leakage Inductance) and the externally mounted reactor inductance. Unless a reactor is connected, n108 (Motor Leakage Inductance) does not have to be set according to the motor. V/f Pattern during Vector Control Set the V/f pattern as follows during vector control: The following examples are for 200 V Class motors. When using 400 V Class motors, double the voltage settings (n012, n015, and n017).

To select the Run/Stop Command or frequency reference, change the mode in advance depending on the following applications. * LOCAL mode: Enables the Digital Operator for Run/Stop Commands and FWD/REV Run Commands. The frequency reference can be set using the potentiometer or . * REMOTE mode: Enables Run Command Selection (n003). The frequency reference can be set using the Frequency Reference Selection (n004). 62 6 Programming Features How to Select LOCAL/REMOTE Mode When LOCAL/REMOTE switching function is not set for multi-function input selection When LOCAL/REMOTE switching function is set for multi-function input selection (When 17 is not set for any of constants n050 to n056) Select Lo for operator LO/RE selection.

Autotuning is possible only for motor 1. Autotuning mode cannot be entered when motor 2 is selected NOTE using a Motor Switching Command allocated to a multi-function input (i.e., Autotuning Selection (n139) setting is not possible). Constant No. n139 Name Autotuning Selection Unit Setting Range Factory Setting - 0 to 2 0 n139 Settings Setting Function 0 Disabled 1 Rotational autotuning (motor 1) 2 Stationary autotuning for motor line-to-neutral resistance only (motor 1) Note: Setting is not possible when motor 2 is selected using a Motor Switching Command allocated to a multi-function input. ("Err" will be displayed on the Digital Operator, and the setting will return to the value before the change.) Use the following procedure to perform autotuning to automatically set motor constants when using the V/f control method, when the cable length is long, etc. Setting the Autotuning Mode One of the following two autotuning modes can be set. * Rotational autotuning * Stationary autotuning for motor line-to-neutral resistance only Always confirm the precautions before autotuning. 66 6 Programming Features * Rotational Autotuning (n139 = 1) Rotational autotuning is used only for open-vector control. Set n139 to 1, input the data from the nameplate, and then press the RUN key on the Digital Operator. The Inverter will stop the motor for approximately 1 minute and then set the required motor constants automatically while operating the motor for approximately 1 minute. NOTE 1. When performing rotational autotuning, be sure to separate the motor from the machine and first confirm that it is safe for the motor to rotate. 2. For a machine in which the motor itself cannot be rotated, set the values from the motor test report. 3. If automatic rotation poses no problem, perform rotational autotuning to ensure performance. * Stationary Autotuning for Motor Line-to-neutral Resistance Only (n139 = 2) Autotuning can be used to prevent control errors when the motor cable is long or the cable length has changed since installation or when the motor and Inverter have different capacities. Set n139 to 2 for open-loop vector control, and then press the RUN key on the Digital Operator. The Inverter will supply power to the stationary motor for approximately 20 seconds and the Motor Line-to-neutral Resistance (n107) and cable resistance will be automatically measured. NOTE 1. Power will be supplied to the motor when stationary autotuning for motor line-to-neutral resistance only is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed. 2. When performing stationary autotuning for motor line-toneutral resistance only connected to a conveyor or other machine, ensure that the holding brake is not activated during autotuning. Precautions before Using Autotuning Read the following precautions before using autotuning. * Autotuning the Inverter is fundamentally different from autotuning the servo system. Inverter autotuning automatically adjusts parameters according to detected motor constants, whereas servo system autotuning adjusts parameters according to the detected size of the load. 67 * When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), use a motor with a rated voltage that is 20 V less than the input power supply voltage of the Inverter for 200Vclass Inverters and 40 V less for 400V-class Inverters. If the rated voltage of the motor is the same as the input power supply voltage, the voltage output from the Inverter will be unstable at high speeds and sufficient performance will not be possible. * Use stationary autotuning for motor line-to-neutral resistance only whenever performing autotuning for a motor that is connected to a load. (To ensure performance, set the value from the motor test report.) * Use rotational autotuning if performing autotuning is possible while not connected to a load. * If rotational autotuning is performed for a motor connected to a load, the motor constants will not be found accurately and the motor may exhibit abnormal operation. Never perform rotational autotuning for a motor connected to a load. * The status of the multi-function inputs and multi-function outputs will be as shown in the following table during autotuning. When performing autotuning with the motor connected to a load, be sure that the holding brake is not applied during autotuning, especially for conveyor systems or similar equipment. Tuning Mode Multi-function Inputs Multi-function Outputs Rotational autotuning Do not function. Same as during normal operation Stationary autotuning for motor line-to-neutral resistance only Do not function. Maintain same status as when autotuning is started. DSPL PRGM * To cancel autotuning, always use the STOP key on the Digital Operator. Precautions for Using Autotuning(when motor voltage > supply voltage) Use the following procedure to perform autotuning if using a motor with a rated voltage higher than the Inverter input power supply. 1. Input the rated voltage from the motor nameplate for the Maximum Voltage (n012). 2. Set the Maximum Voltage Output Frequency (n013) to the base frequency on the motor nameplate. 3. Perform autotuning. 4. Record the Motor No-load Current (n110). 68 6 Programming Features 5. Calculate the rated secondary current of the motor using the following equation: Rated Secondary Current = 2 ( Rated Current ) - ( No-Load Current ) 2 6. Input the power supply voltage for the Maximum Voltage (n012). 7. Input the following calculated value for the Maximum Voltage Output Frequency (n013): Maximum Voltage Output Frequency = Base Frequency on the Motor Nameplate x Power Supply Voltage-------------------------------------------------------------------------------------------------------------------------------------------------------------Rated Voltage on the Motor Namplate 8. Perform autotuning again. 9. Record the Motor No-load Current (n110) again. 10. Calculate the rated secondary current of the motor using the following equation: Rated Secondary Current = Rated Secondary Current calculated in Step 5 x Rated Voltage on Motor Nameplate --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Power Supply Voltage 11. Input the following calculated value for the Motor Rated Slip (n106): Motor Rated Slip = of Poles- Base Freq. from Motor Nameplate - Rated Speed from Motor Nameplate x Number -------------------------------------- 120 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------No-Load Current in Step 4 No-Load Current in Step 9 x ----------------------------------------------------------------------------------Rated Secondary Current in Step 5 NOTE 1. When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set n012 (Max. Voltage) to the input power supply voltage x 0.9. 2. When operating at high speeds (i.e., 90% of the rated speed or higher), the output current will increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current. Operating Procedure 1. Confirm the following: * * * * The motor is separated from the machine system. The motor shaft lock key is removed. If there is a brake, it is released. The wiring is correct. 2. The Inverter power supply is ON. 3. There is no error. 4. Select Program Mode by pressing until is lit. 5. Set the following constants for the selected motor to the nameplate 69 values. Constant No. Name Setting Range Remarks n012 Maximum Voltage 0.1 to 255.0 Set to the rated voltage from the nameplate. n013 Maximum Voltage Output Frequency 0.2 to 400.0 Set to the base frequency from the nameplate. n036 Motor Rated Current 0.0 to 999.9 Set to the rated current from the nameplate. n106 Motor Rated Slip 0.0 to 20.0 Hz Set to the value of the following equation using data from the nameplate: Base frequency - Rated speed x Number of poles / 120 When performing precision setting (i.e., when performing autotuning using a motor test report or design data), the input data to set when autotuning will differ. Refer to the table below. Name Simple Setting Precision Setting Maximum Voltage Motor rated voltage Voltage under no-load conditions at motor rated speed Maximum Voltage Output Frequency Motor base frequency Frequency under no-load conditions at rated speed Motor Rated Slip Base frequency - Rated speed x Number of poles / 120 Slip at rated torque 6. Set the Autotuning Selection (n139). 7. Press the DSPL key to select the autotuning mode. * The Digital Operator will display "TUn." The shows the autotuning method selected for n139. * All function indicators will turn OFF. * The status indicators will return to operation ready status. * Only the , DSPL , and STOP keys will be accepted in autotuning mode. * Autotuning will start when the key is input. * Autotuning will be cancelled when the STOP key is input 70 6 Programming Features * When the DSPL key is input, status will return again to Program Mode, and constants can be changed. 8. Press the key to perform autotuning. Power will be supplied to the motor with the selected autotuning method. * "TUn" will flash during autotuning. * All function indicators will turn OFF. * The status indicators will change to normal operation status. 9. Tuning Completed * When autotuning has been completed properly, "End" will be displayed and constants will be changed according to the tuning results. * When rotational autotuning is completed, the Middle Output Frequency Voltage and Minimum Output Frequency Voltage will be calculated and set according to the selected Maximum Voltage as shown in the following table. Constant No. Name Setting Range Remarks n015 Middle Output Frequency Voltage 0.1 to 255.0 (Factory-set Middle Output Frequency Voltage) x (Maximum Voltage set value) / (Factoryset Maximum Voltage) n017 Minimum Output Frequency Voltage 0.1 to 50.0 (Factory-set Minimum Output Frequency Voltage) x (Maximum Voltage set value) / (Factory-set Maximum Voltage) 10.Press the DSPL key to select the Drive Mode. This completes autotuning. Error Processing during Autotuning * Errors and alarms that occur during normal operation are also detected during autotuning. * If an error or alarm occurs, the motor will coast to a stop (baseblock) and autotuning will be cancelled. 71 * If an error in measurement occurs or the STOP key has been pressed during autotuning, an EXX error will be displayed, the motor will coast to a stop, and autotuning will be cancelled. This error message, however, does not remain in the error log. Refer to page 211 for information on errors. * If autotuning is cancelled, constants changed by autotuning will automatically return to their values before the start of autotuning. * If an error occurs while decelerating to a stop at the end of autotuning, an error will be displayed on the Digital Operator, but autotuning processing will not be cancelled. The results of autotuning will be valid. Precautions after Using Autotuning For a fixed output region, the V/f pattern for the maximum point in the output region must be set after completing autotuning. To increase the motor's rated speed by 1 to 1.2 times or when using a fixed output motor, make the following changes after autotuning. Do not change n012 (Max. Voltage) or n013 (Max. Voltage Output Frequency). * Increasing the Motor's Rated Speed by 1 to 1.2 Times To increase the motor's rated speed by 1 to 1.2 times, use the following formula to change the setting of Max. Output Frequency (n011): Max. output frequency = (motor rated speed) x (no. of motor poles)/120 (Hz) x 1 to 1.2) If the motor's speed is increased beyond the rated speed, fixed output characteristics will be used at high speeds and motor torque will be reduced. * Applications to Constant Output Motors Such as Motors for Machine Tools Use the following formula to change the settings of n011 (Max. Output Frequency) when using a motor with a fixed output, e.g., a motor for a machine tool: n011 = Frequency (Hz) at maximum speed under no-load conditions (load rate = 0) Do not change the motor constants after performing autotuning. 72 6 Programming Features Digital Operator Displays during Autotuning Function indicators on the Digital Operator change during autotuning as in the following diagram.

Set the Carrier Frequency Selection (n080) to 1, 2, 3, or 4 when using vector control mode. Do not set it to 7, 8, or 9. 4. If the Inverter repeatedly stops and starts with a load exceeding 120% of the Inverter rated current within a cycle time of 10 minutes or less, reduce carrier frequency at a low speed. (Set constant n175 to 1.) 5.

When a carrier frequency of 14 kHz (n080) is selected, automatic carrier frequency reduction during low-speed overcurrent is automatically enabled, even if the Reducing Carrier Frequency Selection at Low Speed (n175) is set to 0 (disabled). 7. When the carrier frequency is set to 14 kHz, the following functions will be disabled: * Fast digital input (START/STOP) * UP 2/DOWN 2 * Motor overheat protection using PTC thermistor input * Bi-directional PID output * Frequency offsets Important Operator Stop Key Selection (n007) WARNING The Digital Operator stop button can be disabled by a setting in the Inverter.

Check the status of the Motor Selection Monitor and contactors M1 and M2 with an external sequence or sequencer, and start Inverter operation only after confirming that the motor has been switched. The motor switching process for the Inverter takes 50 ms max. If an attempt is made to switch the motor during operation or when the motor is decelerating to a stop, the switching process will not be performed, a SEr (sequence error) alarm will be displayed, a multi-function output alarm will be output to the Digital Operator, and operation will continue. No error will be output. When the motor comes to a complete stop (i.e., when the Inverter output is OFF), the switching process will be performed. * Electronic Thermal Motor Protection (OL1) Electronic thermal motor protection is performed based on n036 (Motor Rated Current) when motor 1 is selected and based on n161 (Motor 2 Rated Current) when motor 2 is selected. When a Motor Switching Command is allocated for a multi-function input terminal, OL1 calculations for motor 1 and motor 2 are always performed regardless of the status of the Motor Switching Command input terminal. Output current detection data for OL1 calculations is provided separately for motor 1 and motor 2. (If motor 1 is selected, output current detection data is calculated for motor 1 with the actual output current, and output current detection data is calculated for motor 2 with an output current of 0.0 A. If motor 2 is selected, output current detection data will be calculated for motor 2 with the actual output current, and output current detection data will be calculated for motor 1 with an output current of 0.0 A. If motor 2 is selected, output current detection data will be calculated for motor 2 with the actual output current, and output current detection data will be calculated for motor 1 with an output current of 0.0 A.) 103 If constant n037 is set to 3 (standard motor, motor 1 only) or 4 (special motor, motor 1 only), however, OL1 calculations for motor 1 will always be performed, regardless of the status of the Motor Switching Command. (Regardless of whether motor 1 or motor 2 is selected, output current detection data for motor 1 is calculated with the actual output current, and output current detection data for motor 2 is calculated with an output current of 0.0 A.) Constant No. Name Description Factory Setting n037 Electronic Thermal Motor Protection Selection 0: Electronic thermal characteristics for standard motor 1: Electronic thermal characteristics for special motor 2: No electronic thermal motor protection 3:Electronic thermal characteristics for standard motor (motor 1 only) 4: Electronic thermal motor characteristics for special motor (motor 1 only) 0 * Maximum Frequency, Frequency Reference, Acceleration Time, and Deceleration Time When motor 1 is selected, operation is performed using n011 (Maximum Output Frequency) as the maximum frequency. Therefore, when the set value of the Maximum Output Frequency (n011) and the set value of the Motor 2 Maximum Output Frequency (n140) are different, operation is as follows: 1. Even when using an analog frequency reference with the same reference voltage (current), the frequency reference will differ by the ratio between n011 and n140. Example: If n011 = 60 Hz and n140 = 50 Hz, when the reference voltage is 5 V (50%), motor 1 would rotate at 30 Hz and motor 2 would rotate at 25 Hz. 104 6 Programming Features 2. For a multi-step speed reference, the setting unit is Hz (absolute value), and so the motor rotates at the commanded value regardless of the motor selection status. If a multi-step speed reference exceeding the selected maximum output frequency multiplied by the Frequency Reference Upper Limit (n033) is mistakenly input, upper limit operation will be performed at the selected maximum output frequency multiplied by the Frequency Reference Upper Limit (n033). Example: If n011 = 60 Hz, n140 = 50 Hz, and n033 = 100%, operation will be at 50 Hz when a multi-step speed reference of 60 Hz is mistakenly input when motor 2 is selected. 3. Multi-step Speed Reference (n024 to n032) Upper Limit (Setting Range Upper Limit) The upper limit is Maximum Output Frequency (n011) for motor 1 or the Motor 2 Maximum Output Frequency (n140), whichever is greater, multiplied by the Frequency Reference Upper Limit (n033). 4. The setting values of the Acceleration and Deceleration Times (n019 to n022) are the times required to reach the selected maximum output frequency. Example: If n011 = 60 Hz, n140 = 50 Hz, and acceleration (deceleration) time = 10 s, motor 1 will accelerate (decelerate) for 5 s and motor 2 will accelerate (decelerate) for 6 s to reach 30 Hz starting at 0 Hz (or to reach 0 Hz starting at 30 Hz).

Output Frequency (Frequency at DC Injection Braking Startup) n016 (Factory Setting: 1.5 Hz) Time DC Injection Braking Time at Stop (n090) (Factory Setting: 0.5 s) * Changing the frequency reference while running Upon termination of a FWD (REV) Run Command, the motor decelerates at the deceleration rate determined by the time set in Deceleration Time 1 (n020) and DC injection braking is applied immediately before stopping. DC injection braking is also applied when the motor decelerates because the frequency reference is set lower than the Min. Output Frequency (n016) when the FWD (REV) Run Command is ON. If the deceleration time is short or the load inertia is large, an overvoltage (OV) fault may occur at deceleration. In this case, increase the deceleration time or install an optional Braking Resistor. Braking torque: Without braking resistor: Approx. 20% of motor rating With braking resistor: Approx. 150% of motor rating 106 6 Programming Features Coast to a Stop Example when Acceleration/Deceleration Time 1 is selected Acceleration Time 1 Deceleration (n019) Time 1 Output Coast to a (n020) Frequency stop Time FWD (REV) Run Command * Changing the frequency reference while running Upon termination of the FWD (REV) Run Command, the motor starts coasting. Applying DC Injection Braking DC Injection Braking Current (n089) Sets the DC injection braking current in units of 1%. (Inverter rated current=100%) DC Injection Braking Time at Stop (n090) Sets the DC injection braking time at stopping in units of 0.1 s. When the setting of n090 is 0, DC injection braking is not performed, but the Inverter output is turned OFF when DC injection braking is started. n016 Min. Output Frequency n090 DC Injection Braking Time at Stop When coasting to a stop is specified in the Stopping Method Selection (n005), DC injection braking is not applied when stopping. Simple Positioning Control when Stopping * If a sequence input terminal is used for a RUN/STOP sequence, simple positioning control when stopping can be used to reduce deviation in the position where the motor stops after the Run Command is started from the sequence input terminal. 107 * Controlling the Stop Position Regardless of Output Frequency Control is performed so that S, the travel distance from maximum output frequency until decelerating to a stop, and S1, the travel distance from any frequency (less than maximum output frequency) until decelerating to a stop, are the same. (Control is performed to stop at the same position when the Run Command is input from a sequence input terminal regardless of the output frequency.)

Closed: Run according to the potentiometer frequency reference and Run Command from the Digital Operator. Up/Down Commands (Setting: n056 = 34) When the FWD (REV) Run Command is ON, acceleration/deceleration is enabled by inputting the UP or DOWN signal from multi-function input terminals S6 and S7 without changing the frequency reference. Operation can thus be performed at the desired speed. When Up/Down Commands are specified in n056, any function set in n055 is disabled, terminal S6 is the input terminal for the Up Command, and terminal S7 is the input terminal for the Down Command.

Whenever this FWD/REV Run 2 Command is programmed to one of the Multi-function Digital Inputs, it switches between forward (ON) and reverse (OFF) operation, while the standard FWD Run Command (set value 1 for n050 to n056) works as a RUN/STOP command (i.e. it starts and stops the inverter operation). An "ERR" alarm will be displayed when it is tried to set the REV Run Command (set value: 2) and the FWD/REV Run 2 Command (set value: 37) simultaneously. If this is attempted via communications, constant setting error message "oP8" will be displayed, and operation will not be possible.

Stall Prevention (Current Limit) Level during Acceleration (n093) Sets the stall prevention (current limit) level during acceleration in units of 1%. (Inverter rated current = 100%) Factory setting: 170% A setting of 200% disables the stall prevention (current limit) during acceleration. If the output current exceeds the value set for n093 during acceleration, acceleration stops and the frequency is maintained. When the output current goes to the value set for n093, acceleration starts. Motor Current n093 *2 Time Output Frequency *1: Stops the acceleration to prevent the motor from stalling. *2: Release width (hysteresis) of stall prevention during acceleration is approx. 5% of inverter rated current. Time *1 In the constant output area (output frequency > Max. Voltage Output Frequency (n013)), the stall prevention (current limit) level during acceleration is automatically decreased using the following equation. Stall prevention during accel. in constant output area = Max.

(Inverter rated current = 100%) Factory setting: 160% A setting of 200% disables stall prevention (current limit) while running. If the stall prevention action current at speed agreement exceeds the value set for n094 for longer than 100 ms, deceleration starts. If the output current exceeds the value set for n094, deceleration continues. If the output current goes to the value set for n094, acceleration to the set frequency starts. Stall prevention acceleration/deceleration settings during operation are set either for the currently selected Acceleration Time, i.e., for Acceleration Time 1 (n019) and Deceleration Time 1 (n020), or for Acceleration Time 2 (n021) and Deceleration Time 2 (n022). Motor Current n094 *2 Time Output Frequency 100 ms Time *1 132 *1: Decreases the frequency to prevent the mo from stalling. *2: At the start of acceleration, the output curre hysterisis is approx. 5% of Inverter rated current. 6 Programming Features Stall Prevention during Operation Stall Prevention above Base Speed during Run (n115) The stall prevention level can be decreased automatically in the constant output range.

Set Decel Time Time Note: If Stall Prevention during Deceleration is used with simple positioning control, positioning will not be performed properly, so use a set value of 1. 134 6 Programming Features Decreasing Motor Speed Fluctuation Slip Compensation (n002 = 0) As the load becomes larger, the motor speed is reduced and the motor slip value is increased. The slip compensating function controls the motor speed at a constant value even if the load varies. When the Inverter output current is equal to the Motor Rated Current (n036), the compensation frequency is added to the output frequency. Compensation Frequency = Motor Rated Slip (n106) Motor Rated Slip (n106) - Motor No-load Current (n110) x --------------------------------------------------------------------------------------------------------------------------------------------------Motor Rated Current (n036) - Motor No-load Current (n110) x SlipCompensationGain ( n110 ) Related Constants Constant No. Name n036 Motor Rated Current Unit 0.1 A Setting Range 0% to 150% of Inverter rated current n111 Slip Compensation Gain 0.1 0.0 to 2.5 n110 Motor No-load Current 1% 0% to 99% (100%=Motor Rated Current n036) n112 Slip Compensation Time Constant n106 Motor Rated Slip 0.1 s 0.0 to 25.5 s When 0.0 s is set, delay time is 2.0 s. 0.1 Hz 0.0 to 20 Hz Factory Setting * 0.0 * 2.0 s * * Depends on Inverter capacity. (Refer to pages 245 and 246.) Note: 1. Slip compensation is not performed under the following condition: Output frequency < Minimum Output Frequency (n016) 2. Slip compensation is not performed during regeneration. 3. Slip compensation is not performed when the Motor Rated Current (n036) is set to 0.0 A. 135 Motor Protection Motor Overload Detection The V7AZ protects against motor overload with a built-in electronic thermal overload relay. Motor Rated Current (Electronic Thermal Reference Current, n036) Set the rated current value shown on the motor nameplate. Note: Setting n036 to 0.0 A disables the motor overload protective function.

Constant No. n038 Name Electronic Thermal Motor Protection Time Constant Setting Unit 1 min Setting Range 1 to 60 min Factory Setting 8 min The electronic thermal overload function monitors the motor temperature based on Inverter output current and time to protect the motor from overheating. When the electronic thermal overload relay is enabled, an error occurs, and the Inverter output is turned OFF to prevent excessive overheating in the motor. When operating with one Inverter connected to one motor, an external thermal relay is not needed. When operating more than one motor with one Inverter, install a thermal relay on each motor. General-purpose Motors and Inverter Motors Induction motors are classified as general-purpose motors or Inverter motors based on their cooling capabilities. The motor overload function operates differently for these two motor types. 136 6 Programming Features Example for 200 V Class Motors General-purpose Cooling Effect Effective when operated at 50/60 Hz from commercial power supply Torque Characteristics 60 s Short-term Continuous rating Torque (%) Electronic Thermal Overload An error (motor overload protection) occurs when continuously operated at 50/ 60 Hz or less at 100% load. 50 Operation Frequency (Hz) Base Frequency 60 Hz (V/f for 50 Hz, 220 V Input Voltage) For low-speed operation, torque must be limited in order to stop motor temperature rise.

The following graph shows the characteristics of the PTC temperatureresistance value. Resistance () Class F Class H Tr: Temperature Threshold Varies depending on the PTC type, but the resistance value is nearly the same. For example Tr = Class F, 150C Tr' = Class H, 180C 1330 550 Tr - 5 Tr Tr + 5 Tr' Temperature The voltage across the ends of three PTC thermistors connected in series is input to an analog input terminal (FR), and motor OH alarms and motor OH errors are detected according to the voltage in respect to the temperature-resistance characteristics of the PTC thermistor. After a motor OH alarm is detected (FR input > 0.94 V), operation continues according to the n141 Motor Overheat Operation Selection (and the OH8 indicator on the Digital Operator will flash). After a motor error is detected (FR input > 1.87 V), the motor stops according to the n141 Motor Overheat Operation Selection (and the OH9 indicator on the Digital Operator will flash). 138 6 Programming Features Constant No. Name n141 PTC Thermistor Input Motor Overheat Protection Selection Description 0: No overheat protection with PTC thermistor input (FR) Factory Setting 0 1 or higher: Overheat protection with PTC thermistor input (FR) Note: oH8 / oH9 alarm: User can select the inverter decelerate to a stop or not. 1: Only oH8 alarm, not to a stop. 2: oH8 alarm, and decelerate to a stop (oH9 fault output). 3: oH8 alarm, and decelerate to a stop (oH9 fault output) using n022 (Deceleration Time 2) deceleration time 4: oH8 alarm, and coasting to a stop (oH9 fault output) . 5: not oH8 alarm, and decelerate to a stop (oH9 fault output). 6: not oH8 alarm, and decelerate to a stop (oH9 fault output) using n022 (Deceleration Time 2) deceleration time. 7: not oH8 alarm, and coasting to a stop (oH9 fault output). n142 Motor Temperature Input Filter Time Constant Setting Unit: 0.1 s Setting Range: 0.0 to 10.0 s 0.2 sec Note: When the analog signal (0 to 10 V) input into terminal FR is used as the motor overheat signal for the PTC thermistor input (FR) (when n141 is set to 1 or higher), the signal cannot be used as a frequency reference or for PID feedback. (There are restrictions when setting constants.) The following settings cannot be set from the Digital Operator. (After the error is displayed on the Digital Operator, the value returns to the value before the change.) If the following settings are set from the MEMOBUS, a constant setting error will occur. (oP7 will flash on the Digital Operator.) 139 * When n141 is set to 1 or higher: n004 (Frequency Reference Selection) cannot be set to 2, 3, or 4 (frequency reference of 0 to 10 V, 4 to 20 mA, or 0 to 20 mA, respectively). When n128 (PID Control Selection) is set to a value other than 0 (with PID control), n164 (PID Feedback Value Selection) cannot be set to 0, 1, or 2 (feedback values of 0 to 10 V, 4 to 20 mA, or 0 to 20 mA, respectively). * Constant n141 cannot be set to 1 when n004 is set to 2, 3, or 4, and n128 is set to 1 and n164 is set to 0,1, or 2.

Using MEMOBUS (MODBUS) Communications Serial communication is available with V7AZ using a programmable controller (MEMOCON series) and MEMOBUS (MODBUS). Refer to the MEMOBUS Instruction Manual (Manual No.: TOEZ-C736-70.1) for details of communications. MEMOBUS (MODBUS) Communications The MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31 V7AZ units). Communication between master and slave (serial communication) is controlled according to the master program with the master initiating communication and the slave responding. The master sends a signal to one slave at a time. Each slave has a preregistered address number, and the master specifies the number and conducts signal communications. The slave receives the communications to carry out designated functions and reply to the master.

Separate the wiring for communication from the main circuit wiring or other power lines. 2. Use shielded cables for communication wiring; R+ RP2 connect the shielded sheath to the ground terminal and terminate the other end to prevent it from PC SS+ being connected (to prevent noise malfunction). 3. When communication is performed through RS485, connect S+ and R+, S- and R- terminals outside the Inverter as shown at the right. 142 6 Programming Features Procedure for Communications with PLC The following shows the procedure for communications with a PLC. 1. Connect the communication cable between the PLC and the V7AZ with the power supply turned OFF. 2. Turn the power ON. 3. Set the constants (n151 to n157) required for communication by using the Digital Operator. 4. Turn the power OFF once to verify that the Digital Operator displays have been completely erased. 5. Turn the power ON again. 6. Communications with the PLC starts. Setting Constants Necessary for Communication Communication related constants must be set for PLC communication. Constants n151 to n157 cannot be set by communication. Always set them before performing communication.

Monitoring run status from the PLC, setting/referencing of constants, Fault Reset and multi-function input reference can be done regardless of Run Command or frequency reference selection. Multi-function input reference from the PLC becomes OR with input commands from S1 to S7 multi-function input terminals. Message Format For communications, the master (PLC) sends a command to the slave (V7AZ) and the slave responds to it. The configuration for sending and receiving is as shown to the right. The length of the data varies according to the contents of commands (functions). The interval between messages must be maintained at the following amount. Slave address Function code Data Error check PLC - V7AZ V7AZ - PLC Reference Message Response Message 24 bits n156 setting 24 bits PLC - V7AZ Reference Message t (s) 10 ms or more * Slave address: Inverter address (0 to 32) Setting to 0 indicates simultaneous broadcasting. The Inverter does not respond to the command from the master. 144 6 Programming Features * Function code: Command codes (See below.)

Data length depends on the contents of the command. * Error check: CRC-16 (Calculate the value by the following method.) 1. The default value at calculation of CRC-16 is normally 0. In the MEMOBUS system, change the default to 1 (all to 16-bit). 2. Calculate CRC-16 assuming that the loop address LSB is MSB and the last data MSB is LSB. 3. Also calculate CRC-16 for a response message from the slave and refer it to CRC-16 in the response message. * Read Out Holding Register Contents (03H) Reads out the contents of the specified number of continuous holding registers. The contents of each holding register is divided into the upper 8 bits and the lower 8 bits. They become the data items in the response message in numerical order. 145 Example: Reads out the status signal, fault contents, data link status, and frequency reference from the V7AZ (slave 2).

(Reset is enabled during run.) Storing Constants [Enter Command] (can be written only.) Register No. 0900H Name Contents Enter Write in constant data to nonCommand volatile memory (EEPROM) Setting Range Factory Setting 0000H to FFFFH - When a constant is written from the PLC by communications, the constant is written to the constant data area on the RAM in the V7AZ. The Enter Command is a command to write the constant data on the RAM to the non-volatile memory in the V7AZ. This Enter Command is executed when data, regardlesss of the value, is written to register number 0900H. With the factory setting, an Enter Command is accepted only while the Inverter is stopped. By changing constant n170, an Enter Command can be accepted even while the Inverter is running. CAUTION While the constant is being stored after an Enter Com- mand was issued, response to the commands or data input with the keys on the Digital Operator (JVOP-140) becomes poor. Be sure to take some measures for an emergency stop by using the external terminals (setting the external terminal to Run Command priority, or setting the multi-function input terminal to external fault, External Baseblock or emergency stop). NOTE Maximum number of writing times of the non-volatile memory used for V7AZ is 100,000; do not execute the Enter Command excessively. When a constant is changed from the Digital Operator, the constant data on the RAM is written to the non-volatile memory without the Enter Command. Constant No. Name Unit n170 Enter Command operation selection (MEMOBUS communications) - Setting Factory Range Setting 0, 1 0 155 n170 Setting Description 0 Accepts the Enter Command (constant saving) while the Inverter is stopped. 1 Always accepts the Enter Command (constant storing). The new constant becomes valid even if the Enter Command is not input. If the Enter Command is not used, however, the value returns to the stored value when the power supply is turned ON again. Register number 0900H is used only for write-in. If this register is readout, a register number error (error code: 02H) occurs. 156 6 Programming Features Error code Error Code 01H Contents Function code error * Function code from PLC is other than 03H, 08H, or 10H. Improper register number 02H * No register numbers to be accessed have been registered. * Enter Command "0900H" (an exclusive-use register for write-in) was read out. Improper quantity 03H * The number of data items to be read or written-in is not in the range between 1 and 16. * The number of data items in a message is not the value obtained by multiplying the quantity by two in the write-in mode. Data setting error 21H * A simple upper/lower limit error occurred with control data or constant write-in. * A constant setting error occurred when a constant was written. Write-in mode error 22H * Attempt to write in a constant from PLC was made during running.* * Attempt to write in an Enter Command from PLC was made during running (n170=0). * Attempt to write in a constant from PLC was made during UV occurrence. * Attempt to write in an Enter Command from PLC was made during UV occurrence. * Attempt to write in a constant other than n001=12, 13 (constant initialization) from PLC was made during "F04" occurrence. * Attempt to write in a constant from PLC was made while data were being stored. * Attempt to write in data exclusive for read-out from PLC was made. * Refer to the constants list for constants that can be changed during operation. 157 Performing Self-test V7AZ is provided with a function to perform self-diagnosis for operation check of the serial communication I/F circuit. This function is called self-test. In the self-test, connect the sending terminal with the receiving terminal in the communication section. It checks if the data received by V7AZ is not being changed. It also checks if the data can be received normally. Carry out the self-test in the following procedure. 1. Turn ON the V7AZ power supply. Set constant n056 to 35 (selftest). 2. Turn OFF the V7AZ power supply. 3. Make the following wiring with the power supply turned OFF. 4. Turn the power ON. S7 P1 S4 R+ P2 SC PC R- S+ S- (Note: Select NPN side for SW1.) Normal operation: Operator displays frequency reference value. Faulty operation: Operator displays , fault signal is turned ON and Inverter ready signal is turned OFF. 158 6 Programming Features Using PID Control Mode For details on the PID control settings, refer to the block diagram of the Inverter's internal PID control or the block diagram of the Operator analog speed reference. PID Control Selection (n128) Constant No. Name Unit Setting Range Factory Setting n128 PID Control Selection - 0 to 8 0 Setting Function 0 Disabled. 1 Enabled: Deviation is subject to derivative control. 2 Enabled: Feedback signal is subject to derivative control. 3 Enabled: Frequency reference + PID output, and deviation are subject to derivative control. 4 Enabled: Frequency reference + PID output, and feedback signal are subject to derivative control. 5 Enabled: Deviation is subject to derivative control. 6 Enabled: Feedback signal is subject to derivative control. 7 Enabled: Frequency reference + PID output, and deviation are subject to derivative control. 8 Enabled: Frequency reference + PID output, and feedback signal are subject to derivative control. PID Output Characteristics Forward Reverse (Reverse the PID output.) 159 Set one of the above values when using PID control. The following table shows how to determine the target value and the feedback value to be input when PID control is enabled. Input Target Value The currently selected frequency reference Feedback Value The frequency reference that is set in the PID Feedback Value Selection (n164) n164 Setting Condition Determined by the Frequency Reference Selection (n004). When LOCAL mode is selected, the target value is determined by the Frequency Reference Selection in Local Mode (n008). When multi-step speed references are selected, the currently selected frequency reference will be the target value. - Description 0 Control circuit terminal FR, Voltage: 0 to 10 V 1 Control circuit terminal FR, Current: 4 to 20 mA 2 Control circuit terminal FR, Current: 0 to 20 mA 3 Operator terminal, Voltage: 0 to 10 V 4 Operator terminal, Current: 4 to 20 mA 5 Pulse train Note: 1. When selecting a frequency reference from the control circuit terminal FR as the target or feedback value, the V-I switch of SW2 on the control circuit board must be selected depending on the input method (current or voltage input). 2. Never use the frequency reference from the control circuit terminal FR for both the target and feedback values. The frequency reference for both the target value and the feedback value becomes the same. Example: When the frequency reference from the control circuit terminal FR, with a voltage of 0 to 10 V, is selected as the target value and n004=2, and when at the same time the frequency reference from the control circuit terminal FR, with a current of 4 to 20 mA, is selected as the feedback value and n164=1, the feedback value will be set as the frequency reference from the control circuit terminal FR with a voltage of 0 to 10 V. 160 6 Programming Features 3. When using an analog signal (0 to 10 V/4 to 20 mA) input to the CN2 terminal of the JVOP-140 Digital Operator as the target or feedback value of PID control, do not use it as a multi-function analog input. Constant n077 (Multi-function Analog Input Function) must be set to 0 (disabled in this case). Proportional Gain (P), Integral Time (I), Derivative Time (D) (n130, n131, n132) Adjust the response of the PID control with the proportional gain (P), integral time (I), and derivative time (D). Constant No. Name Unit Setting Range Factory Setting n130 Proportional Gain (P) 0.1 0.0 to 25.0 1.0 n131 Integral Time (I) 0.1 s 0.0 to 360.0 1.0 n132 Derivative Time (D) 0.01 s 0.00 to 2.50 0.00 Optimize the responsiveness by adjusting the constants while operating an actual load (mechanical system). Any control (P, I, or D) that is set to zero will not operate. Upper Limit of Integral (I) Values (n134) Constant No. Name Unit Setting Range Factory Setting n134 Upper Limit of Integral Values 1% 0 to 100 100 Constant n134 prevents the calculated value of integral control from exceeding a specific amount. There is normally no need to change the setting. Reduce the setting if there is a risk of load damage, or of the motor going out of step by the Inverter's response when the load suddenly changes. If the setting is reduced too much, the target value and the feedback value will not match. Set this constant as a percentage of the maximum output frequency with the maximum frequency as 100%. 161 PID Offset Adjustment (n133) Constant No. Name Unit Setting Range Factory Setting n133 PID Offset Adjustment 1% -100 to 100 0 Constant n133 adjusts the PID control offset. If both the target value and the feedback values are zero, adjust n133 so that the Inverter output frequency is zero. Primary Delay Time Constant for PID Output (n135) Constant No. Name Unit Setting Range Factory Setting n135 Primary Delay Time Constant for PID Output 0.1 s 0.0 to 10.0 0.0 Constant n135 is the low-pass filter setting for PID control outputs. There is normally no need to change the setting. If the viscous friction of the mechanical system is high or if the rigidity is low, causing the mechanical system to resonate, increase the setting so that it is higher than the resonance frequency period. PID Output Gain (n163) Constant No. Name Unit Setting Range Factory Setting n163 PID Output Gain 0.1 0.0 to 25.0 1.0 Constant n163 adjusts the PID control output gain. PID Feedback Gain (n129) Constant No. Name Unit Setting Range Factory Setting n129 PID Feedback Gain 0.01 0.00 to 10.00 1.00 Constant n129 is the gain that adjusts the feedback value. 162 6 Programming Features PID Feedback Loss Detection (n136, n137, n138) Constant No. Name Unit Setting Range Factory Setting - 0: No detection of PID feedback loss 1: Detection of PID feedback loss, operation continued: FbL alarm 2: Detection of PID feedback loss, output turned OFF: Fault 0 0 n136 Selection for PID Feedback Loss Detection n137 PID Feedback Loss Detection Level 1% 0 to 100 100%/Max. output frequency n138 PID Feedback Loss Detection Time 0.1 s 0.0 to 25.5 1.0 PID Upper Limit Sets the upper limit after PID control as a percentage of the maximum output frequency. Prohibition of PID Output Zero limit occurs when the PID output is negative. Analog Position Control with Bi-directional PID Output(n145) If the Bi-directional Function Selection (n145) is set to 1 (enabled), the following functions will be enabled as bi-directional functions: * PID Control Selection (n128) 0 (Enabled) and Bi-directional PID Prohibit Input from Multi-function Input = OFF (Bi-directional PID Function Enabled): If the frequency reference is negative after PID control, the input rotation direction command will be reversed, and the frequency reference will be converted to an absolute value. (If Reverse Run Prohibit (n006) is set to 1, however, reverse operation will not be performed and the frequency reference will be limited to 0 Hz.) 163 Bidirectional Reference Control PID Control Selection (n128) 0 (Enabled) and Bi-directional PID Prohibit Input from a Multi-function Input = ON (Bi-directional Range Function Enabled): If the frequency reference is from 0% to 50% after PID control, the input rotation direction command will be reversed. If the reference is from 50% to 100%, operation will be performed without reversing the input rotation direction command. The frequency reference at this time is shown in the following diagram.

A backup power supply is not necessary because EEPROM is used. The constant copy function is possible only for the Inverters with the same product series, power supply specifications, and control mode (V/ f control or vector control). However, some constants may not be copied. It is also impossible to copy constants between V7AZ and VS mini J7 Inverters. Prohibiting reading constants from the Inverter can be set in n177. The constant data cannot be changed when this constant is set. If an alarm occurs when copying constants, PRGM will flash and copying will continue. To remove the Digital Operator from the Inverter, turn OFF NOTE the input power supply of the Inverter and confirm that the display on the Digital Operator has turned OFF. If the Digital Operator is removed while the power is ON, the Inverter may be damaged. Constant Copy Function Selection (n176) Depending on the setting of n176 (Constant Copy Function Selection), the following functions can be used. 1. Reading all the constants from the Inverter (READ) and storing them in EEPROM in the Digital Operator 2. Copying the constants stored in the Digital Operator to the Inverter (COPY) 3. Verifying that the constants in the Digital Operator and the constants in the Inverter are the same (VERIFY) 4. Displaying the maximum applicable motor capacity and the voltage class of the Inverter for which constants are stored in the Digital Operator 5. Displaying the software number of the Inverter for which constants are stored in the Digital Operator 168 6 Programming Features Constant No. Name Unit Setting Range Factory Setting n176 Constant Copy Function Selection - rdy: Ready rEd: Read CPy: Copy vFy: Verify vA: Inverter capacity display Sno: Software No. display rdy Prohibiting Constant Read Selection (n177) Select this function to prevent accidentally overwriting the constants stored in EEPROM in the Digital Operator. Reading is not possible when this constant is set to 0. The constant data stored in the Digital Operator are safe from accidental overwriting.

Write-in is possible only for Inverters with the same product series, power supply specifications, and control mode (V/ f control or vector control). Therefore, writing from 200 V Class to 400 V Class Inverters (or vice versa), from V/f control mode to vector control mode Inverters (or vice versa), or from V7AZ to VS mini J7 Inverters is not possible. The Constant Copy Function Selection (n176), Constant Read Selection Prohibit (n177), Fault History (n178), Software Version No. (n179), and hold output frequency are not written. vAE will appear (flashing) if the capacities of the Inverters differ. Press ENTER to continue writing (the COPY function). Press STOP/RESET to stop the COPY function. The following constants are not written if the Inverter capacities differ. Constant No. Constant No. Name V/f Settings n108 Motor Leakage Inductance n036 Motor Rated Current n109 Torque Compensation Voltage Limiter n080 Carrier Frequency Selection n110 Motor No-load Current n105 Torque Compensation Iron Loss n140 Energy-saving Coefficient K2 n106 Motor Rated Slip n158 Motor Code n107 Motor Line-to-neutral Resistance n011 to n017 Name Constants added with software version upgrades will not be written between V7AZ Inverters without the additional constants and V7AZ Inverters with the additional constants. For this reason, the settings for the additional constants will not be changed by the copy operation. 172 6 Programming Features Example: Writing Constants from EEPROM in Operator to Inverter Explanation * Enable the settings for constants n001 to n179. * Press DSPL Operator Display and PRGM will light. * Press ENTER to display the set value. * Change the set value to 4 by pressing the or key. * Press ENTER .

A setting range check and matching check for the written constants are executed after the constants are written from the Digital Operator to the Inverter. If a constant error is found, the written constants are discarded and the constants stored before writing are restored. When a setting range error is found, the constant number where an error occurs is indicated by flashing. When an inconsistency in the settings is found, (: a number) is indicated by flashing. 173 VERIFY Function This function compares the constants stored in the Digital Operator with the constant in the Inverter. Verification is possible only for the Inverters with same product series, power supply specifications, and control mode (V/f control or vector control). When the constants stored in the Digital Operator are the same as those in the Inverter, vFy will flash, and then End will be displayed. When the constants are not the same, the unmatched constant number will be displayed. Constants added with software version upgrades will be displayed when VERIFY is performed for V7AZ Inverters without the additional constants and V7AZ Inverters with the additional constants. 174 6 Programming Features Example: Comparing Constants Stored in EEPROM in Operator with Constants in Inverter Explanation * Enable the settings for constants n001 to n179.

When V/f control mode is selected, the n097 setting becomes invalid, and overtorque/undertorque is detected by output current. Setting 186 Description 0 Overtorque/undertorque detected by output torque. 1 Overtorque/undertorque detected by output current. 6 Programming Features Using Inverter for Elevating Machines CAUTION If using an Inverter with an elevator, take safety mea- sures on the elevator to prevent the elevator from dropping. Failure to observe this caution may result in injury. When using the V7AZ for elevating machines such as elevators and cranes, make sure that the brake holds and observe the following precautions for safe operation. Brake ON/OFF Sequence * For the holding brake's ON/OFF sequence, use the following Inverter output signals according to the set control mode. NOTE Do not use "Running (Set value: 1)" for the holding brake's ON/OFF interlock signal. Brake ON/OFF Signals Control Mode V/f Control*1 (n002=0) Signal Name Frequency detection 1 Constant*2 n058=4 Brake ON/OFF Level Adjustment Signal Name Frequency detection level Constant n095=2.50 Hz to 4.00 Hz*3 * 1. For Vector control (n002=1), use the same brake ON/OFF sequence with the same signals as for V/f control. * 2. Shows the setting when a multi-function photocoupler output terminal (P1-PC) is used. * 3. Usually, make the following settings for the frequency detection (n095): For V/f control: Motor rated slip frequency +1 Hz For Vector control: 2.5 Hz to 3.0 Hz If the set value is too low, the motor torque is insufficient and the load may shift when the brake is applied. Be sure to set n095 to a value larger than that of the Minimum Output Frequency (n016) and larger than that of the braker releasing width shown in the following figure. If the set value is too large, the motor may not run smoothly when it starts running. 187 Releasing Width -2 Hz Output Frequency n095 Time ON Frequency Detection Level 1 Up Down High/Low OFF * Sequence Circuit Configuration and Timing Chart Examples For the AC sequence cirHolding Brake cuit, connect the signal Inverter V7AZ Auxiliary Relay Coil between P1 and PC to the +24V Fault Contacts MA sequence circuit with a MB Sequence S1 BR Circuit relay.

Stall Prevention during Deceleration If connecting a braking resistor to discharge regenerative energy, be sure to set the stall prevention during deceleration (n092) to 1. If the stall prevention during deceleration (n092) is set to the NOTE factory setting 0 (Enabled), the motor may not stop within the specified decelerating time. The Stall Prevention during Acceleration (n093) and the Stall Prevention Level during Running (n094) should be set to their factory settings to enable these functions. Settings for V/f Pattern and Motor Constants To set the control mode and the V/f pattern, refer to the instruction manual. If the Vector control method is used, also set the motor constants. Momentary Power Loss Restart and Fault Restart Do not use the momentary power loss restart and fault restart functions in applications for elevating machines. Make sure that n081=0 and n082=0. If these functions are used, the motor coasts to a stop with the brake contact open when a momentary power loss or fault occurs during operation, possibly resulting in serious accidents. I/O Open-phase Protection and Overtorque Detection The I/O open-phase protection is only available for 5.5 kW and 7.5 kW models. To prevent the machine from falling when the motor is open-phase or in a similar situation, enable the I/O open-phase protection (n166 to n169) and the overtorque detection (n096 to n099). At the factory, these constants are set so that these functions are disabled. Also, take safety measures such as protection against falls on the machine. Carrier Frequency Set the carrier frequency selection (n080) to 5 kHz or more (n080: 2 to 4 or 12) to secure the motor torque even if an overcurrent occurs (the current is limited). 189 External Baseblock Signal If the External Baseblock Command (settings 12 and 13 of n050 to n056) is input while the motor is running, the motor will immediately coast to a stop. Do not input the External Baseblock Command while the motor is running unless necessary. If using the External Baseblock Command for an emergency stop or to start run of an interlock, make sure that the holding brake operates. If the External Baseblock Command is input and immediately reset, the Inverter does not output voltage during the minimum baseblock time, which is 0.5 to 0.7 seconds depending on the Inverter capacity. Do not use the External Baseblock Command in an application where the motor is frequently stopped and started. Acceleration/Deceleration Time If the delay time for the holding brake's mechanical operation is not taken into consideration and the acceleration/deceleration time on the Inverter side is set to a time that is too short, an overcurrent or wear on the brakes may occur at starting or the load will shift at stopping because the holding brake does not operate on time. If so, use the Scurve characteristic function or lengthen the acceleration/deceleration time to tune the timing for the holding brake. Contactor on the Inverter's Output-side Do not install a contactor between the Inverter and the motor. If a contactor must be installed because of local electrical codes or regulations or to operate motors with an Inverter, excluding emergencies, open or close the contactor only where the holding brake is fully closed and the Inverter is in baseblock status with the baseblock signal ON. If the contactor is opened or closed while the Inverter is controlling the motor or DC injection braking, surge voltage or a current from the motor by full-voltage starting may cause an Inverter fault. When a contactor is installed between the Inverter and the motor, enable the I/O open-phase protection (n166 to n169). For more information on using Inverters exclusively for elevators or cranes, contact your OMRON representatives or the nearest OMRON sales office. 190 6 Programming Features Using MECHATROLINK-II Communications MECHATROLINK-II can be used with the SI-T/V7 option unit.

Failure to observe this warning may result in an electrical shock. * Disconnect all power before performing maintenance or inspection, and then wait at least one minute after the power supply is disconnected. Confirm that all indicators are OFF before proceeding. If the indicators are not OFF, the capacitors are still charged and can be dangerous. * Do not perform a withstand voltage test on any part of the V7AZ. The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to high voltage. * Only authorized personnel should be permitted to perform maintenance, inspection, or parts replacement. (Remove all metal objects (watches, bracelets, etc.) before starting work.) (Use tools which are insulated against electrical shock.) Failure to observe these warnings may result in an electric shock. CAUTION 192 * The control PCB employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. * Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit.

Inverter alarms are classified into alarm display and fault display. Alarm display:When a minor fault occurs in the Inverter, the Digital Operator flashes the display. In this case, the operation is continued, and restored automatically as soon as the cause is removed. Multi-function output can output the minor fault status to external devices. Fault display: When a major fault occurs in the Inverter, the protective function operates, and the Digital Operator lights the display and shuts off the output to stop the Inverter. The fault can be output as a fault output to the external devices by multi-function output. To reset the fault, turn ON the reset signal with the Run Command OFF or cycle the power after taking the corrective action. * Selecting "always ON" mode at fan operation selection, the power must be cycled to release the alarm display. Corrective Actions of Models with Blank Cover 1. Input fault reset or cycle the power supply OFF and ON. 2. When a fault cannot be corrected: (1) Turn the power supply OFF and check the wiring and external circuit (sequence). (2) Turn the power supply OFF and replace the blank cover with the Digital Operator to display faults. The faults are displayed after turning the power ON. 197 Corrective Actions of Models with Digital Operator : ON : Flashing : OFF Alarm Display Alarm Displays and Meaning Alarm Display Digital Operator Inverter Status Detected as an alarm only.

Tuning results were outside the setting range for constants. - * * * * The motor did not accelerate in the specified time. * * * E12 Current detection error * * * Current flow exceeded motor rated current. The sign of the detected current was reversed. At least one of phases U, V, and W is open. Check input data. Check wiring and the machine environment. Check the load. Check input data. Check motor wiring. Disconnect the motor from the machine system if connected during rotational autotuning. Change the Maximum Voltage if the Maximum Voltage is higher than the Inverter input power supply voltage. Increase Acceleration Time 1 (n019). If Stall Prevention Level during Acceleration (n093) has been lowered, return it to the initial value. Disconnect the motor from the machine system, if connected. Check the current detection circuit, motor wiring, and current detector installation. 211 Troubleshooting Trouble The motor does not operate when an external operation signal is input. Cause Set the RUN command (n003) to Control Circuit Terminal. A 3-wire sequence is in effect. The Multi-function Input Selection (n052) is set to 3-wire sequence, and the S2 control terminal is not closed. To use a 3-wire sequence, make the wiring so that the S2 control terminal is closed. To use a 2-wire sequence, set the Multi-function Input (n052) to a value other than 3-wire sequence. The frequency reference is too low. Input a frequency reference greater than the Min. Output Frequency (n016). The RUN command (n003) is not set to Control Circuit Terminal. The input frequency reference is lower than the setting for the Min.Output Frequency (n016). Local mode is in effect. Set the LO/RE selection of the Digital Operator to RE. The V-I SW (SW2) setting is wrong. For analog input, make sure that the Frequency Reference (n004) and SW2 settings are correct. The setting of NPN/PNP switch (SW1) is not correct. Set SW1 correctly. Program mode is enabled. Press DSPL to make FREF flash and change to Drive mode. The stall prevention level during acceleration is too low. Check if the Stall Prevention Level during Acceleration (n093) is set to an appropriate value. The stall prevention level during running is too low. Check if the Stall Prevention Level during Running (n094) is set to an appropriate value. The load is too heavy. * Example: The reference 4 to 20 mA is input, but SW2 is set to "V." The motor stops. The torque is not output. Because the Stall Prevention Level during Acceleration (n093) is set too low, the output current reaches the set level, the output frequency is stopped, and the acceleration time is lengthened. Because the Stall Prevention Level during Running (n094) is set too low, the output current reaches the set level, and the speed drops. If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened. 212 Corrective Actions The operation method selection is wrong. * Lengthen the set acceleration time (n019). Reduce the load. When the maximum frequency (n011) was changed, the maximum voltage frequency (n013) was also changed. To increase the speed of a generalpurpose motor, only change the maximum frequency (n011). The V/f set value is too low. Set the V/f (n011 to n017) according to the load characteristics. 8 Fault Diagnosis Trouble Cause The motor speed is unstable. The motor speed fluctuates when operating with a light load. The stall prevention level during running is too low. Check if the Stall Prevention Level during Running (n094) is set to an appropriate value. The load is too heavy. Reduce the load. The carrier frequency is too high. Decrease the carrier frequency (n080). The V/f set value is too high for a low-speed operation. Set the V/f (n011 to n017) according to the load characteristics. The maximum frequency (n011) and maximum voltage frequency (n013) were incorrectly adjusted. Set the maximum frequency (n011) and the maximum voltage frequency (n013) according to the motor specifications. The Inverter is used for an operation at 1.5 Hz or less. Do not use the V7 Inverter for an operation that runs at 1.5 Hz or less. For an operation at 1.5 Hz or less, use a different Inverter model. The analog reference input is unstable and has noise interference. Increase the set value for the filter time constant (n062). The power is not being supplied. Check if the power is being supplied. Because the Digital Operator is not correctly mounted, the display does not appear. Mount the Digital Operator correctly. Short-circuit bar for terminals +1 and +2 is not connected. Confirm that the short-circuit bar is connected properly. POWER charge indicator lamp lights but the Digital Operator does not give any display after the power supply is turned ON. Since the main circuit fuse is blown, replace the Inverter. Because the Stall Prevention Level during Running (n094) is too low, the output current reaches the set level and the speed drops. Corrective Actions If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened. If operating the motor with a light load, a high carrier frequency may cause the motor speed to fluctuate. Because the set value for the V/f is too high, over-excitation occurs at low speeds. Example: To operate a 60-Hz motor at 40 Hz or less, the maximum frequency and base frequency are set to 40 Hz. The LED of the Digital Operator is unlit. The breaker or other component on the power input side is not turned ON, and the power is not being supplied. 213 9 Specifications Standard Specifications (200 V Class) Voltage Class 200 V single-/3-phase 3-phase 20P1 20P2 20P4 20P7 21P5 22P2 24P0 25P5 Single-phase B0P1 B0P2 B0P4 B0P7 B1P5 B2P2 B4P0 - - Max.

CE Markings CE markings indicate conformance to safety and environmental standards that apply to business transactions (including production, imports, and sales) in Europe. There are unified European standards for mechanical products (Machine Directive), electrical products (Low Voltage Directive), and electrical noise (EMC Directive). CE markings are required for business transactions in Europe (including production, imports, and sales). The V7AZ Series Inverters bear CE markings indicating conformance to the Low Voltage Directive and the EMC Directive. * Low Voltage Directive: 73/23/EEC 93/68/EEC * EMC Directive: 89/336/EEC 92/31/EEC 93/68/EEC Machinery and installations that incorporate the Inverter are also subject to CE markings. It is ultimately the responsibility of customers making products incorporating the Inverter to attach CE markings to the finished products. The customer must confirm that the finished products (machines or installations) conform to the European Standards. Requirements for Conformance to CE Markings Low Voltage Directive V7AZ Series Inverters satisfy testing for conformance to the Low Voltage Directive under the conditions described in European Standard EN50178. Requirements for Conformance to the Low Voltage Directive V7AZ Series Inverters must satisfy the following conditions in order to conform to the Low Voltage Directive. * Only basic insulation to meet the requirements of protection class 1 and overvoltage category II is provided with control circuit terminals. Additional insulation may be necessary in the end product to conform to CE requirements. 247 * For 400 V Class Inverters, always ground the supply neutral to conform to CE requirements. EMC Directive V7AZ Series Inverters satisfy testing for conformance to the EMC Directive under the conditions described in European Standard EN61800-3. Installation Method In order to ensure that the machinery or installation incorporating the Inverter conforms to the EMC Directive, perform installation according to the method below. * Install a noise filter that conforms to European Standards on the input side. (Refer to EMC Noise Filter on page 251.) * Use a shielded line or metal piping for wiring between the Inverter and Motor. Make the wiring as short as possible. * For details of installation method, refer to Installation Manual (document No. EZZ006543.) 248 10 Conformance to CE Markings Installation and Wiring of Inverter and Noise Filter (Model: CIMR-V720P1 to 27P5), (Model: CIMR-V740P1 to 45P5) L1 L2 L3 PE Control Panel Metal Mounting Plate 3-phase Noise Filter L1 L2 L3 Grounding Face E Inverter RST UVW E Shielded Cable Grounding Face Motor cable: 20 m max.
