Overload or reduced cooling capability during low-speed operation Current more than 150% of the rated output current flew and overcurrent shut-off did not occur. Temperature rise of the heat sink. Ground fault occurred on the inverter's output side. External thermal relay provided for protection from overheat was actuated (contact open). Stall prevention was activated to drop the running frequency to 0. (OL appears while stall prevention is activated.) Communication errors occurred consecutively more than the permissible number of retries when the RS-485 connector is used and communication parameter n5 = "- - -". RS-485 communication error occurred. Communication was broken for a period set in communication parameter n6. (Only for the type with RS-485 function.) Error occurred in the parameter stored. Control Panel Indication Function Name (PUE) PU disconnected (RET) Retry count (CPU) CPU error Definition PU was disconnected when communication parameter n17 = "1". This function is valid for only the type with RS-485 communication function. Operation could not be resumed properly within the preset number of retries. Arithmetic operation of the built-in CPU does not end within the predetermined time. *1. Resetting the inverter initializes the internal thermal integral data of the electronic overcurrent protection. *2. Activated only when "1" is set in Pr. 40 "start-time ground fault detection selection". *3. Activated only when any of Pr. 60 to Pr. 63 (input terminal function selection) is set to OH. (2) Minor failures Control Panel Indication (FN) Function Name Definition The cooling fan built in the inverter failed (stopped). Fan trouble Remarks In this product, the cooling fan does not start until the start signal ( RUN key, STF, STR signal) turns on. (Refer to Pr. 76 "cooling fan operation selection".) (3) Warnings Control Panel Indication Function Name Definition (OL) Stall prevention (overcurrent) (*4) (oL) Stall prevention (overvoltage) (PS) PU stop (Stopped with PU STOP key) (UV) Undervoltage (Err) During reset Current more than 150% of the rated inverter current flew in the motor and operation is being performed to prevent the inverter from resulting in overcurrent shutoff. Regenerative energy of the motor became excessive and operation is being performed to stop the frequency from decreasing to prevent overvoltage shut-off. Pr. 75 "PU stop selection" had been set STOP and a stop was made by pressing the RESET key of the operation panel or parameter unit (FR-PU04) during operation in the external operation mode. Power supply voltage of the inverter dropped. During inverter reset (RES signal is ON) * 4. The stall prevention operation current may be set to any value.

When undervoltage occurs, no alarm output is provided but the output is shut off. After power restoration, the inverter may be run as it is. Depending on the running status (e.g. load magnitude), however, overcurrent, regenerative overvoltage or other protection may be activated at power restoration. (In external operation mode.) *2. The magnitude of braking torque indicates the short-duration average torque (which changes with the motor loss) developed when the motor alone is decelerated from 60Hz in the shortest period, and is not continuous regenerative torque. Deceleration made from a high speed above the base frequency will reduce the value of average deceleration torque. *3. This function is valid for only the type with RS-485 communication function. *4. Compatible with only the product having the built-in cooling fan. *5. Activated only when "1" is set in Pr. 40 "start-time ground fault detection selection". *6. Activated only when external thermal relay input (OH) is selected in any of Pr. 60 to Pr. 63 (input terminal function selection). 43 9.

(1) EMC Directive 1) Our view of transistorized inverters for the EMC Directive A transistorized inverter is a component designed for installation in a control box and for use with the other equipment to control the equipment/device. Therefore, we understand that the EMC Directive does not apply directly to transistorized inverters. For this reason, we do not place the CE mark on the transistorized inverters. (The CE mark is placed on inverters in accordance with the Low Voltage Directive.) The European power drive manufacturers' organization (CEMEP) also holds this point of view. 2) Compliance We understand that the transistorized inverters are not covered directly by the EMC Directive. However, the EMC Directive applies to machines/equipment into which transistorized inverters have been incorporated, and these machines and equipment must carry the CE marks. Hence, we prepared the European Standard-compliant noise filters and the technical information "EMC Installation Guidelines" (information number BCN-A21041-202) so that machines and equipment incorporating transistorized inverters may conform to the EMC Directive more easily. 3) Outline of installation method Install an inverter using the following methods: * Use the inverter with an European Standard-compliant noise filter. * For wiring between the inverter and motor, use shielded cables or run them in a metal piping and ground the cables on the inverter and motor sides with the shortest possible distance. * Insert a line noise filter and ferrite core into the power and control lines as required. Full information including the European Standard-compliant noise filter specifications are written in the technical information "EMC Installation Guidelines" (BCN-A21041-202). Please contact your sales representative. 46 (2) Low Voltage Directive 1) Our view of transistorized inverters for the Low Voltage Directive Transistorized inverters are covered by the Low Voltage Directive. 2) Compliance We have self-confirmed our inverters as products compliant to the Low Voltage Directive and place the CE mark on the inverters. 3) Outline of instructions * Connect the equipment to the earth securely. Do not use an earth leakage circuit breaker as an electric shock protector without connecting the equipment to the earth. * Wire the earth terminal independently. (Do not connect two or more cables to one terminal.) * Use the cable sizes on pages 7, 9 and 11 under the following conditions. * Ambient Temperature: 40C (104F) maximum * Wire installation: On wall without ducts or conduits If conditions are different from above, select appropriate wire according to EN60204 ANNEX C TABLE 5. * Use the no-fuse breaker and magnetic contactor which conform to the EN or IEC Standard. Design notice: Where residual-current-operated protective device (RCD) is used for protection in case of direct or indirect contact, only RCD of Type B is allowed on the supply side of this Electronic Equipment (EE). Otherwise another protective measure shall be applied such as separetion of the EE from the environment by double or reinforced insulation or isolation of EE and supply system by a transformer. (Extract from EN51078) * Use the inverter under the conditions of overvoltage category II and contamination level 2 or higher specified in IEC664. * Use the breaker of type B (breaker which can detect both AC and DC). If not, provide double or enhanced insulation between the inverter and other equipment, or put a transformer between the main power supply and inverter. * On the input and output of the inverter, use cables of the type and size set forth in EN60204 Appendix C. * The operating capacity of the relay outputs (terminal symbols A, B, C) should be 30VDC, 0.3A. * The terminals indicated as the control circuit input and output terminals on page 5 are separated safely from the main circuit. * Environment Ambient Temperature Ambient Humidity Muximum Altitude During operation -10C to +50C (14F to 122F) 90% RH or less 1,000m (3280.80feet) In storage -20C to +65C (-4F to +149F) 90% RH or less 1,000m (3280.80feet) During transportation -20C to +65C (-4F to +149F) 90% RH or less 10,000m (32808.40feet) Details are given in the technical information "Low Voltage Directive Conformance Guide" (BCN-A21041-203). Please contact your sales representative. 47 Appendix 2 Instructions for compliance with U.S. and Canadian Electrical Codes 1. General Precaution The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for residual voltage between terminal P (+) and N (-) with a meter etc., to avoid hazard of electrical shock. 2. Environment Before installation, check that the environment meets following specifications. Ambient temperature Ambient humidity Storage temperature (Note 2) Ambience Altitude vibration -10C to +50C (14F to 122F) (non-freezing) 90%RH or less (non-condensing) -20C to +65C (-4F to 149F) Indoors (No Corrosive and flammable gases, oil mist, dust and dirt.) Below 1000m (3280.80feet), 5.9m/s2 or less 3. Installation The below types of inverter have been approved as products for use in enclosure and approval tests were conducted under the following conditions. Design the enclosure so that the ambient temperature, humidity and ambience of the inverter will satisfy the above specifications. Branch circuit protection For installation in United States, branch circuit protection must be provided, in accordance with the National Electrical Code and any applicable local codes. For installation in Canada, branch circuit protection must be provided in accordance with the Canada Electrical Code and any applicable provincial codes. 4. Short circuit ratings Suitable For Use in A Circuit Capable of Delivering Not More Than 5kA rms Symmetrical Amperes. 48 5. Motor overload protection These inverters provide solid state motor overload protection. Set parameter 9 using the following instructions, (Pr. 9 "electronic thermal O/L relay"). <Setting> * Set the rated current [A] of the motor. (Normally set the rated current at 50Hz.) * Setting "0" makes the electronic overcurrent protection (motor protective function) invalid. (The inverter's protective function is valid). * When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 to choose the 100% continuous torque characteristic in the low-speed range. Then, set the rated motor current in Pr. 9. CAUTION * When two or more motors are connected to the inverter, they cannot be protected by the electronic overcurrent protection. Install an external thermal relay to each motor. * When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics of the electronic overcurrent protection will be deteriorated. In this cause, use an external thermal relay. * A special motor cannot be protected by the electronic overcurrent protection. Use an external thermal relay. 49 REVISIONS *The manual number is given on the bottom left of the back cover. Print Date Mar., 2000 *Manual Number IB(NA)-0600026-A First edition Revision
