Before installing and putting this equipment into operation, read these safety instructions and warnings carefully. Also read and obey all the warning signs attached to the equipment. Make sure that the warning labels are kept in a legible condition and replace any missing or damaged labels. WARNING This equipment contains dangerous voltages and controls dangerous rotating mechanical parts. Loss of life, severe personal injury or property damage can result if the instructions contained in this manual are not followed. Only suitably qualified personnel should work on this equipment, and only after becoming familiar with all safety notices, installation, operation and maintenance procedures contained in this manual. * Use only permanently wired input power connections. The equipment must be grounded (IEC 536 Class 1, NEC and other applicable standards) * Use only Residual Current-operated protective Device (RCD) type B if an RCD is required * Wait at least five minutes after the power has been turned off, before opening the equipment. The dc-link capacitor remains charged to dangerous voltages even when the power is removed. When working on open equipment, note that live parts are exposed and do not touch these parts * Do not connect machines with a threephase power supply, fitted with EMC filters, to a supply via an ELCB (Earth Leakage Circuit Breaker - see EN50178, section 6.5) * Note that certain parameter settings may cause the inverter to restart automatically after an input power failure * Do not use this equipment as an "emergency stop" mechanism (see EN 60204, 9.2.5.4) * Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment * Note that the following terminals can carry dangerous voltages even when the inverter is inoperative: Power supply terminals Motor terminals Additional terminals MICROMASTER Eco MIDIMASTER Eco L/L1, N/L2 and L3 U, V and W B+/DC+ and BDC+ and DC- * This equipment is capable of providing internal motor overload protection in accordance with UL508C section 42. Refer to P074. Motor overload protection can also be provided by using an external PTC. * This equipment is suitable for use in a circuit capable of delivering not more than 100,000 symmetrical amperes (rms), for a maximum voltage of 230 / 460 V * when protected by a time delay fuse *. * As detailed in the Eco Reference Manual. * Do not use the unit with a motor of a higher nominal power rating than the inverter, or a nominal power less than half that of the inverter. Only operate the inverter when the nominal current in P083 exactly matches the motor rating plate nominal current * Enter the motor data parameters (P080P085) and do an auto-calibration (P088) before the motor is started. Unstable/unpredictable motor operation (e.g. Reverse rotation) may result if this is not done. If this instability occurs, the mains supply to the inverter must be disconnected. * When using the analog input, the DIP switches must be correctly set and the analog input type selected (P023) before enabling the analog input with P006. If this is not done the motor may start inadvertently. * Lowering the fan tray on Frame size C MICROMASTER Eco exposes rotating parts. Power must be isolated prior to this operation.

EUROPEAN LOW VOLTAGE DIRECTIVE The MICROMASTER Eco and MIDIMASTER Eco product range complies with the requirements of the Low Voltage Directive 73/23/EEC as amended by Directive 93/68/EEC. The units are certified for compliance with the following standards: EN 60146-1-1 Semiconductor convertersGeneral requirements and line commutated converters EN 60204-1 Safety of machineryElectrical equipment of machines EUROPEAN MACHINERY DIRECTIVE The MICROMASTER Eco and MIDIMASTER Eco product range do not fall under the scope of the Machinery Directive. However, the products have been fully evaluated for compliance with the essential Health & Safety requirements of the directive when used in a typical machine application. A declaration of incorporation is available on request. EUROPEAN EMC DIRECTIVE When installed according to the recommendations described in this manual, the MICROMASTER Eco and MIDIMASTER Eco product range fulfil the requirements of the EMC Directive as defined by the EMC Product Standard for Power Drive Systems EN 61800-3 UL and CUL listed power conversion equipment type 5B33 for use in pollution degree 2 environment ISO 9001 Siemens plc operates a quality management system which complies with the requirements of ISO 9001. 3 of 23 G85139-H1751-U555-D1 Siemens INTRODUCTION ............................................................... GENERAL TYPES OF SYSTEM CONTROL These are the Operating Instructions for the MICROMASTER Eco and MIDIMASTER Eco and are to be used for quick and simple commissioning only. The MICROMASTER and MIDIMASTER Eco inverters are normally controlled using the keypad or input/output terminals. However, there is an option for remote operation using the RS485 Dtype connection on the front panel, see the Eco Reference Manual for further details. For more details and the complete parameter list for specific applications consult the Eco Reference Manual on our website (details available on back page). The Eco range of inverters comprises variable frequency inverters for controlling the speed of fans and pump motors. The Eco can also be programmed to manage many other motor functions and limits. These functions are set by parameters which are programmed using the keypad. The output frequency and hence the motor speed can be controlled by digital or analog inputs. The digital inputs can be programmed to control the motor speed by means of: * frequency set points, keys using the * fixed frequencies, via binary inputs * motorized potentiometer function The analog inputs can be programmed for voltage or current input in conjunction with DIP selector switches. Closed loop process control, using a standard Proportional, Integral, Derivative (PID) control loop function can be selected. This control is set-up using DIP selector switches and analog input 2. A 15V, 50 mA supply is provided to power the feedback transducer. Siemens G85139-H1751-U555-D1 4 of 23 MECHANICAL INSTALLATION ....................................... MOUNTING The IP20/21 range of Eco units can be mounted side-by-side without space in between. A clearance distance of at least 100mm top and 160 mm bottom must be left free for the movement of cooling air. IP56 Eco units must have a clearance distance of at least 150mm in all directions. A good bonding between the Eco and the metal back plate is necessary to ensure good grounding and low RF (radio frequency) impedance. If necessary remove some back plate paint and/or use toothed washers to ensure safety and EMC (electro-magnetic compatibility). Use an earth braid on 400V ratings 1.5KW and below. Ambient temperature MICROMASTER Eco 0oC to 50oC. MIDIMASTER Eco (IP20/21/56) 0oC to 40oC. Ensure that the Eco is not subject to shock, vibration or atmospheric pollutants. When units are selected which include integral filters they will meet the conducted and radiated RF emissions limits specified in EN 55011. CONTROL AND SERIAL COMMUNICATION CABLES To minimise the effects of radio frequency emissions and interference:* Screened control and data cables should be used with the Eco. MOTOR CABLES To minimise the effects of radio frequency emissions:* Screened cables should be used between the Eco and the motor. * Keep cables to motor as short as possible, generally under 25m. * Terminate cable screens correctly (use gland fittings which give 360 deg. conduction) on both the Eco gland plate and the motor terminal box. * Fit suppressors on all contactor coils. * If an external input EMC filter is to be fitted then ensure that it is positioned as close as possible to the Eco and is well grounded to the metal back plate. Use screened cable between the external input EMC filter and the Eco input terminals, and ground cable screen correctly. 5 of 23 All MICRO/MIDIMASTER Eco products comply with the requirements of the EMC Directive when installed in accordance with the wiring recommendations of this manual. The units comply with European Norm EN61800-3 "Adjustable speed electrical power drive systems". This standard specifies different limits for domestic and industrial applications, which defines whether an integral EMC filter is required. For further information refer to the Eco Reference Manual. * Terminate the control and data cable screens correctly on the Eco by using the gland plate and/or clamps provided. Consult the instructions for the Building Management System or controller at the opposite cable end. * IT IS MOST IMPORTANT THAT THE MOTOR AND CONTROL CABLES ARE KEPT APART. IF CONTROL AND POWER CABLES NEED TO CROSS, ARRANGE THE CABLES SO THAT THEY CROSS AT 90 IF POSSIBLE. CIRCULATING CURRENTS If there is a slight difference between the chassis potential of the Eco and the Building Management System (or controller) then circulating currents can occur in the control or data cable screens. These circulating currents should be avoided by separately connecting the chassis of both pieces of equipment securely to the same earthing point. G85139-H1751-U555-D1 Siemens ELECTRICAL INSTALLATION ......................................... CONNECTING TO MAINS DIP Switch's Terminals L/L1, N/L2 & L3 Control Terminals Ensure that the nameplate voltage of the Eco (and the motor) corresponds to the mains supply voltage to be used. PE L/L1 N/L2 Check that the supply circuit protection is correctly rated for the Eco nameplate input current. L3 Ensure that all power cables are adequately rated for the expected duty.

STOP Button RUN Button LED Display UP / INCREASE speed The Eco has three ranges of parameters; Display mode, Basic mode and Expert mode. One of the Basic mode parameters (P199) controls access to the Expert mode parameters. The Basic mode parameters are described in this section. A list of the Expert mode parameters is contained in the next section. For further information on using Expert mode, refer to the Reference Manual (G85139-H1750-U630). I O PARAMETER RANGES P ACCESSING PARAMETERS AND CHANGING VALUES DOWN / DECREASE speed RS485 Interface Parameterisation Button THE KEYPAD The keypad comprises membrane-type keys as well as an integral 4-digit 7-segment LED display. The keys are limited to [run], [stop], [up], [down] and [P]. All parameters can be accessed and changed using the keys. The and keys are used to change parameter values. The keys have two modes of operation. A single momentary press will change the value by a value of 1. Keeping the button pressed for longer initiates scrolling and allows values to be changed rapidly. To access a parameter and change its value, follow the simple sequence described below: Key P PARAMETER TYPES 1 True value parameters. For example, setting parameter P003 to 10 seconds tells the Eco to take 10 seconds to slow the motor from its normal operating speed to stopped (ramp-down time). 2 Limited range parameters. The values themselves are not relevant and only represent the function required. For example, parameter P199 can only be set to 0 to 1. Setting the value to 0 tells the Eco to give access to the basic parameters only. Setting the value to 1 gives access to the expert parameters. 9 of 23 Display Press P to enter parameter mode Use the [up] and [down] keys to select the required parameter number (e.g. ramp-up time) There are three types of parameter: 3 `Read only' parameters. The values of these parameters are factory set and provide the user with information. For instance, parameter P111 is a read only parameter and indicates the inverter's variable torque power rating in kW. Action P Press P to confirm that you wish to enter a value for that parameter. The current value is displayed Use the [up] and [down] keys to enter the required value P Press P to confirm that you have changed the value as required. The parameter number is re-displayed. Use the [up] and [down] keys to return the parameter number to the display default parameter. P Press P to return to default display The display will alternate between the setpoint frequency and actual output frequency, which will be 0 Hz. G85139-H1751-U555-D1 Siemens DISPLAY MODE PARAMETERS...................................... Parameter Function Range Default Units P000 Operating display - (output frequency) Hz Displays the output selected by P001 (an Expert mode parameter). Display selection via P001: 0 = Output frequency (Hz) 1 = Frequency setpoint (i.e. speed at which inverter is set to run) (Hz) 2 = Motor current (A) 3 = DC-link voltage (V) 4 = Motor torque (% nominal) 5 = Motor speed (rpm) 6 = USS serial bus status (Code) 7 = PID Feedback signal (%) 8 = Output voltage (V) The default setting (0) displays the inverter output frequency. If the inverter is in stand-by mode, the flashing display will alternate between the setpoint frequency and actual output frequency, which will be 0 Hz when not being run. In the event of a failure, the relevant fault code (Fnnn) is displayed. BASIC MODE PARAMETERS.................................... Parameter Function Range Default Units P002 Ramp-up time 0 - 650.0 20 Seconds This is the time taken for the motor to accelerate from standstill to the maximum frequency. The maximum frequency is set by parameter P013. Setting the ramp-up time too short can cause the inverter to trip (Fault code F002 = overcurrent). P003 Ramp-down time 0 - 650.0 20 Seconds This is the time taken for the motor to decelerate from maximum frequency to standstill. The maximum frequency is set by parameter P013. Setting the ramp-down time too short can cause the inverter to trip (Fault code F001 = DC link overvoltage). This is also the period for which injection braking is applied, if selected (refer to parameter P073 in Expert mode). P003 Frequency setpoint source selection 0-2 0 - The value of this parameter (0, 1 or 2) selects the mode of control of the inverter's frequency setpoint. 0 = digital motorised potentiometer. The inverter runs at the frequency set in P005 (refer to Expert mode) and can be controlled with the [up] and [down] keys. If P007 (see below) is set to 0, the frequency can be increased or decreased by setting any two of the digital inputs (P051 to P055 or P356 - refer to Expert mode) to the values of 11 and 12. 1 = Analog. The inverter output frequency is controlled by analog input signals (0-10V, 0/4-20mA or potentiometer). 2 = Fixed frequency. Fixed frequency is only selected by setting the value of at least one of the digital inputs (P051 to P055 or P536 - refer to Expert mode) to the value of 6 or 7. Siemens G85139-H1751-U555-D1 10 of 23 BASIC MODE PARAMETERS.......................................... Parameter Function Range Default Units P007 Keypad control 0 or 1 1 - The value of this parameter (0 or 1) configures keypad control. 0 = Control is by digital inputs (P051 to P055 or P356 - refer to Expert mode) 1 = Front panel (keypad) control enabled. However, the level of control enabled from the keypad is determined by the values of P121 to P124 (refer to Expert mode). P012 Minimum motor frequency 0.0- 150.0 0.00 Hz This value sets the minimum motor frequency and must logically be less then the value of P013 (see below P013 Maximum motor frequency 0.0- 150.0 50,00 (60.00 = North Hz America) This value sets the maximum motor frequency. To maintain stable operation, this value should not exceed 3x the motor rating plate nominal frequency (see below). P016 Start on the fly 0 or 2 0 Flying restart P016=0 Flying restart disabled P016=2 Flying restart enabled Allows the inverter to start onto a spinning motor. Always enter the correct motor nameplate details when enabling this feature.

You must use the data provided on the motor's rating plate. - Perform an automatic calibration (P088 = 1 - refer to Expert mode) if any of the parameters P081 to P085 are changed from their factory default settings. - When the inverter is set-up for North America operation (P101 = 1 - refer to Expert mode), P081 will default to 60 Hz and P085 will indicate in hp (range = 016 to 530). P199 Access to Expert mode 0 or 1 - - This value enables or disables access to Expert mode parameters. 0 = Normal mode parameter values only can be changed. 1 = Expert mode parameter values can be changed in addition to the Normal mode parameters. It is possible to reset all parameter values (including motor data, P081 to P085) to their factory default settings using Expert parameter P944=1. 11 of 23 G85139-H1751-U555-D1 Siemens EXPERT MODE - IMPORTANT PARAMETERS ..............

G85139-H1751-U555-D1 14 of 23 EXPERT MODE - IMPORTANT PARAMETERS.............. Parameter P071 P073 Function Range (Default) Description/Notes Slip compensation (%) 0-200 The inverter can estimate the amount of slip in an asynchronous motor at varying loads and increase its output frequency to compensate for this. This parameter `fine tunes' the compensation for different motors in the range 0 - 200% of the calculated slip. WARNING: This parameter must be set to zero when using synchronous motors or motors that are connected in parallel. This is because overcompensation can cause instability. DC injection braking (%) 0-200 [0] [90] This rapidly stops the motor by applying a DC braking current and holds the shaft stationary until the end of the braking period. Additional heat is generated within the motor. Range is Braking is effective for a period of time set by P003. variant The DC brake can be activated using DIN 1 to DIN 6 dependent (see P051 to P055 and P356). WARNING: Frequent use of long periods of DC injection braking can cause the motor to overheat. If DC injection braking is enabled via a digital input then DC current is applied for as long as the digital input is high. This causes heating of the motor. P076 Pulse frequency 0-7 [0] Sets the pulse frequency (from 2 to 16 kHz) and PWM mode. If silent operation is not absolutely necessary, the losses in the inverter as well as the RFI emissions can be reduced by selecting lower pulse frequencies. 0/1 = 16 kHz 2/3 = 8 kHz 4/5 = 4 kHz (400 V default) 6/7 = 2 kHz The default switching frequency FS8 and FS9 (110 kW to 315 kW) is set to 2 kHz. Even numbers = normal modulation technique. Odd numbers = lower loss modulation technique used when operating mainly at speeds above 5 Hz. P077 Control mode 0 to 6 [0] 15 of 23 Note: Selecting 8KHz or 16KHz may reduce the output current rating. 0 = Multi-motor mode 4 = Energy saving mode 5 = Linear V/f characteristic with variable torque 6 = Square V/f (Fan and Pump characteristic) G85139-H1751-U555-D1 Siemens EXPERT MODE - IMPORTANT PARAMETERS .............. Parameter Function P079 Starting boost P080* Nominal rating plate motor power factor P086 Motor current limit (%) Range (Default) 0 -250 [50] Description/Notes Sets additional current during ramping to ensure consistent starting and to overcome stiction effects 0,00 -1,00 If efficiency is shown on the motor rating plate, calculate the power factor as follows: pf = (cos.j) . hp x 746 . 1.732 x efficiency x nom. volts x nom. amps 0-200 [100] Defines the motor overload current as a % of the nominal motor current (P083) allowed for up to one minute. With this parameter, the motor current can be limited and overheating of the motor prevented. If this set value is exceeded for one minute; the output frequency is reduced until the current falls to that set in P083. The inverter can be made to trip by using the relay in conjunction with P074. P088 Automatic calibration 0-1 [1] Note: The maximum value that P086 can be set to is automatically limited by the rating of the inverter. When P088 is set to `1' and the RUN button is pressed, the inverter automatically measures the stator resistance; stores it in P089 and then resets P088 to `0'. This calibration has to be carried out each time the motor is changed.
