INSTALLATION WARNING THIS EQUIPMENT MUST BE EARTHED. To guarantee the safe operation of the equipment it must be installed and commissioned properly by qualified personnel in compliance with the warnings laid down in these operating instructions. Take particular note of the general and regional installation and safety regulations regarding work on high voltage installations (e.g. VDE), as well as the relevant regulations regarding the correct use of tools and personal protective gear. Make sure that the unobstructed clearance for each of the cooling inlets and outlets above and below the inverter is at least 100 mm (200 mm on all sides for IP54 variants). Ensure that the temperature does not exceed the specified level when the inverter is installed in a cubicle. Avoid excessive vibration and shaking of the equipment. Inverter models MM25 and MM25/2, MM37 and MM37/2, MM55 and MM55/2, and MM75 and MM75/2 must be fixed securely to a flat surface before use to prevent access to the capacitors contained within the heatsink. Note: Consider the possible use of options (e.g. RFI suppression filters) at the planning stage. 2.1 Wiring Guidelines to Minimise the Effects of EMI The inverters are designed to operate in an industrial environment where a high level of Electro–Magnetic Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble–free operation. However, if problems are encountered, the following guidelines may prove useful. In particular, grounding of the system 0V at the inverter, as described below, may prove effective. Figure 2 illustrates how an RFI suppression filter should be installed. (1) Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. metal brackets) are preferred as they have lower impedance at high frequencies. The return earth from motors controlled by the inverters should be connected directly to the earth connection (PE) on the associated inverter. (2) Use saw–tooth washers when mounting the inverter and ensure that a good electrical connection is made between the heatsink and the panel, removing paint if necessary. (3) Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that unscreened wires are not left visible. (4) Separate the control cables from the power connections as much as possible, using separate trunking, etc. If o control and power cables cross, arrange the cables so that they cross at 90 if possible. (5) Ensure that contactors in the cubicle are suppressed, either with R–C suppressors for AC contactors or ‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relays on the inverter. (6) Use screened or armoured cables for the power connections and ground the screen at both ends via the cable glands. (7) If the drive is to be operated in a noise–sensitive environment, the RFI filter kit should be used to reduce the conducted and radiated interference from the inverter. In this case, the filter should be mounted as close to the inverter as possible and well grounded (see (2) above) and the supplied metallised cover should be fitted to the inverter. (8) Select the lowest switching frequency possible. This will reduce the amount of EMI generated by the inverter. On no account must safety regulations be compromised when installing inverters! Siemens plc 1996  G85139–E1720–U325–B 13 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions When attempting to meet specific EMC limits by using a filter, the INVERTER following points must be observed: (1) All cables to and from the Terminate screen to metal inverter (including control panel by removing cable 100 mm cables) must be screened using sheath. to 300 mm suitable glands. (2) The control cable must be kept separate from the motor and SCREENED mains cables. CABLE SCREENED LN (3) It may be necessary to fit a CABLE screened lid to the inverter.

Asynchronous and synchronous motors can be connected to the MICRO MASTER inverter either individually or in parallel. Note that if a synchronous motor is connected to the inverter, the motor current may be two and a half to three times greater than that expected. WARNING Ensure that the motor is configured for the correct supply voltage. Single/three phase 230 V MICRO MASTERS must not be connected to a 400 V three phase supply. When synchronous machines are connected or when coupling several motors in parallel, the inverter must be operated with voltage/frequency control characteristic (P077= 0 or 2) and slip compensation must be disabled (P071 = 0).

The cover on the MIDI MASTER is attached to the heatsink by four or six M4 screws, depending on the variant. Remove each of the screws and then lift off the cover. The electrical terminals are now exposed (see Figure 8). Note: The cover on IP54 variants is held in place by four screws. THIS COVER IS HEAVY AND MUST BE SUPPORTED WHILE THE SCREWS ARE REMOVED. CAUTION On the printed circuit boards that are now exposed are highly sensitive CMOS components that are particularly sensitive to static electricity. For this reason, avoid touching the boards or components with your hands or metal objects. Only the terminal screws may be touched with insulated screwdrivers when connecting the leads. The power, control and motor cables enter the inverter from the bottom. When connecting them to the appropriate terminal blocks ensure that they are connected correctly and that the equipment is properly earthed. CAUTION The control, power supply and motor leads must be laid separately. They must not be fed through the same cable conduit/trunking. o Use screened cable for the control lead. Use Class 1 60/75 C copper wire only. Tightening torque for the field wiring terminals is either 1.1 Nm for variants up to 18.5 kW or 2.5 – 3.0 Nm for 22/30/37 kW variants.

Ensure that the appropriate circuit–breakers with the specified current rating are connected between the power supply and inverter (see section 1.4). Connect the power input to the power terminals L1, L2, L3 and earth using a 4–core cable. For cross–section of each core see section 1.4. Use a 4–core cable to connect the motor.

Figure 9: Mains Input / Motor Terminal Connections – MIDI MASTER The total length of the motor lead should not exceed 100 m. If a screened motor lead is used or if the cable channel is well grounded, the maximum length should be 50 m. Cable lengths up to 200 m are possible by using additional output chokes (see Catalogue DA64). Asynchronous and synchronous motors can be connected to the MIDI MASTER inverter either individually or in parallel. Note that if a synchronous motor is connected to the inverter, the motor current may be two and a half to three times greater than that expected. WARNING Ensure that the motor is configured for correct supply voltage. When synchronous machines are connected or when coupling several motors in parallel, the inverter must be operated with voltage/frequency control characteristic (P077= 0 or 2) and slip compensation must be disabled (P071 = 0).

FRONT PANEL CONTROLS WARNING The equipment must not be switched on until after its cover has been fitted. After the power has been turned off, you must always wait five minutes so that the dc–link capacitors can discharge. Do not remove the cover until this time has elapsed. As a precautionary measure, the digital frequency setpoint has been set at 0.0 Hz in the factory. This prevents inadvertent and uncontrolled running of the motor occurring at initial start–up. Before the motor will run it is necessary to enter a frequency setpoint via parameter P000 with the
button, or to set it with parameter P005. All settings must only be entered by qualified personnel, paying particular attention to the safety precautions and warnings. The parameter settings required can be entered using the three parameterisation buttons (P,
and ) on the front panel of the inverter (Figure 13 contains a flowchart for the procedure for setting parameter values). The parameter numbers and values are indicated on the four digit LED display. Note: On IP54 MIDI MASTERS the control panel is sealed behind a hinged access door (see Figure12). To access the panel, undo the four retaining screws and open the access door. WARNING IP54 protection is only valid while the access door is closed. If the unit is wet, disconnect the power and wipe the cover dry before opening the door otherwise water may seep inside.

OPERATING INFORMATION Refer to the parameter list in section 5 for a full description of each parameter. 4.1 General (1) The inverter does not have a main power switch and is therefore live when the mains supply is connected. It waits with the output disabled for the RUN button to be pressed or for an ON signal via terminal 8 (rotate right) or terminal 9 (rotate left) – see parameters P051 – P055. (2) If output frequency (P001 = 0) is selected as the display, the corresponding setpoint is displayed approximately every 1.5 seconds while the inverter is stopped. (3) The inverter is programmed at the factory for standard applications on Siemens four–pole standard motors. When using other motors it is necessary to enter the specifications from the motor’s rating plate into parameters P081 to P085 (see Figure 14). Note that access to these parameters is not possible unless P009 has been set to 002 or 003. If the inverter is to be used with an 8–pole motor, set P082 to twice the nominal speed of the motor. Be aware that this will cause the display to show twice the real RPM when P001 is set to 005. P081 P084 1LA5053–2AA20 3� Mot Nr. E D510 3053 12 022 IEC 56 MADE IN GERMANY IP54 Rot.

(4) When delivered, the inverter’s frequency setpoint is set to 0.00 Hz, which means that the motor will not rotate! To make it start up, a setpoint must be entered using the � button or entering a value in P005. (5) When a parameter value has been set, it is stored automatically in the internal memory. 4.2 Basic Operation The most basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only the minimum number of parameters to be changed from their default settings. (1) Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted (see Figure 13 for the procedure). (2) Set parameter P005 to the desired frequency setpoint. (3) Check parameters P081 to P085 and ensure that they match the requirements stated on the rating plate on the motor (see Figure 14). (4) Press the RUN button ( I ) on the inverter’s front panel. The inverter will now drive the motor at the frequency set by P005. If required, the motor’s speed (i.e. frequency) can be varied directly by using the �� buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory during periods when the inverter is not running.) Siemens plc 1996 G85139–E1720–U325–B  26 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions 4.3 Operation – Digital Control For a basic startup configuration using digital control, proceed as follows: (1) Connect control terminal 7 to terminal 8 via a simple on/off switch. This sets up the inverter for clockwise rotation (default). (2) Refit the cover and then apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted (see Figure 13 for the procedure). (3) Check that parameter P006 is set to 000 to specify digital setpoint. (4) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 8) in this case) and disable the front panel controls. (5) Set parameter P005 to the desired frequency setpoint. (6) Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 14). (7) Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005. 4.4 Operation – Analogue Control For a basic startup configuration using analogue voltage control, proceed as follows: (1) Connect control terminal 7 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise rotation (default). (2) Connect a 4.7 kΩ potentiometer to the control terminals as shown in Figure 7 (MICRO MASTER) or Figure 10 (MIDI MASTER) or connect a 0 – 10 V signal from pin 2 and pin 4 (0V) to pin 3. (3) Set the position of SW1 for voltage (V) input. (4) Refit the cover and then apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted (see Figure 13 for the procedure). (5) Set parameter P006 to 001 to specify analogue setpoint. (6) Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 8) in this case) and disable the front panel controls. (7) Set parameters P021 and P022 to specify the minimum and maximum output frequency settings. (8) Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 14). (9) Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue control voltage) until the desired frequency is displayed on the inverter. 4.5 Stopping the Motor Stopping can be achieved in several ways: • Cancelling the ON command or pressing the OFF button (O) on the front panel causes the inverter to ramp down at the selected ramp down rate (see P003). • OFF2 – operation causes the motor to coast to a standstill (see parameters P051 to P055). • OFF3 – operation causes rapid braking (see parameters P051 to P055). • DC injection braking up to 250% causes an abrupt stop after cancellation of the ON command (see P073). • Resistive braking (see parameter P075). Siemens plc 1996  G85139–E1720–U325–B 27 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions 4.6 If the Motor Does Not Start Up If the motor does not start up when the ON command has been given, check that the ON command is valid, check if a frequency setpoint has been entered in P005 and check that the motor specifications have been entered correctly under parameters P081 to P085. If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when the RUN button is pressed, check that P121 = 001 (RUN button enabled). If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory default parameter values by setting parameter P944 to 001 and then pressing P. 4.7 Local and Remote Control The inverter can be controlled either locally (default), or remotely via a USS data line connected to the internal interface terminals (13 and 14) or to the RS485 D–type connector on the front panel. When local control is used, the inverter can only be controlled via the front panel or the control terminals. Control commands, setpoints or parameter changes received via the RS485 interface have no effect. For remote control, the serial interface is designed as a 2–wire connection for bi–directional data transmission. Refer to parameter P910 in section 5 for the available remote control options. Note: Only one RS485 connection is allowed. You can use either the front panel D–type interface (e.g. to connect an Enhanced Operator Panel (OPm)) or terminals 13 and 14, but not both. When operating via remote control the inverter will not accept control commands from the terminals. Exception: OFF2 or OFF3 can be activated via parameters P051 to P055 (refer to parameters P051 to P055 in section 5). Several inverters can be connected to an external control unit at the same time. The inverters can be addressed individually. Note: If the inverter has been set up to operate via the serial link but does not run when an ON command is received, try reversing the connections to terminals 13 and 14 on X501 (MICRO MASTER) or X1 (MIDI MASTER). For further information, refer to the following documents: E20125–B0001–S302–A1 Application of the USS Protocol in SIMOVERT Units 6SE21 and MICRO MASTER (German) E20125–B0001–S302–A1–7600 Application of the USS Protocol in SIMOVERT Units 6SE21 and MICRO MASTER (English) 4.8 Closed Loop Control 4.8.1 General Description Both the MICRO MASTER and MIDI MASTER provide a PID control loop function for closed loop control (see Figure 15). The control loop is ideal for temperature or pressure control, or other situations where the controlled variable changes slowly or where transient errors are not critical. This control loop is not suitable for use in systems where fast response times are required. Note: The closed loop function is not designed for speed control, but can be used for this provided you do not require fast response times. When closed loop control is enabled (P201 = 001 or 002), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50.0 = 50%. This allows general purpose control of any process which is actuated by motor speed and for which a suitable transducer is available.

This input accepts either a 0 – 5 V or a 0 – 20 mA input (determined by the setting of SW2) and has 8–bit resolution. If an analogue setpoint is not required, the feedback signal can be connected to X501/X1 terminal 3 and terminal 4. This input accepts either a 0 – 10 V or a 0 – 20 mA input (determined by the setting of SW1), has 10–bit resolution and permits a differential (floating) input. If this option is to be used, the values of parameters P006, P023 and P024 should all be set to 000. 4.8.3 Parameter Settings Closed loop control cannot be used unless P201 is first set to 001 or 002, depending on the hardware connection point. Most of the parameters associated with closed loop control are shown in Figure 13. Other parameters which are also associated with closed loop control are as follows: P001 (value = 007) P010 (only if P001 = 007) P061 (value = 012 or 013) P062 (value = 012 or 013) P210 P220 Descriptions of all closed loop control parameters are provided in section 5.

SYSTEM PARAMETERS Parameters can be changed and set using the membrane–type buttons to adjust the desired properties of the inverter, such as ramp times, minimum and maximum frequencies, etc. The parameter numbers selected and the setting of the parameter values are indicated in the four digit LED display. Note: If you press the

[1.00] P011 Frequency setpoint memory 0 – 1 0 = Disabled [0] 1 = Enabled after switch–off. i.e. The setpoint alterations made with the
/  buttons are stored even when power has been removed from the inverter. P012 • Minimum motor frequency (Hz) 0 – 650.00 Sets the minimum motor frequency (must be less than the value of P013). [0.00] P013 • Maximum motor frequency (Hz) 0 – 650.00 Sets the maximum motor frequency. [50.00] P014 • Skip frequency (Hz) 0 – 650.00 A skip frequency can be set with this parameter to avoid the effects of [0.00] resonance of the inverter. Frequencies within +/–2 Hz of this setting are suppressed. Stationary operation is not possible within the suppressed frequency range – the range is just passed through. P015 • Automatic restart 0 – 1 Setting this parameter to ‘1’ enables the inverter to restart automatically [0] after a mains break or ‘brownout’, provided the run/stop switch is still closed. 0 = Disabled 1 = Automatic restart P016 • Start on the fly 0 – 4 Allows the inverter to start onto a spinning motor. [0] Under normal circumstances the inverter runs the motor up from 0 Hz. However, if the motor is still spinning or is being driven by the load, it will undergo braking before running back up to the setpoint – this can cause an overcurrent trip. By using a flying restart, the inverter ‘homes in’ on the motor’s speed and runs it up from that speed to the setpoint. (Note: If the motor has stopped or is rotating slowly, some ‘rocking’ may occur as the inverter senses the direction of rotation prior to restarting.) 0 = Normal restart 1 = Flying restart after power up, fault or OFF2 ( if P018 = 1). 2 = Flying restart every time (useful in circumstances where the motor can be driven by the load). 3 = As P016 = 1 except that the inverter will only attempt to restart the motor in the direction of the requested setpoint. The motor is prevented from ‘rocking’ backwards and forwards during the initial frequency scan. 4 = As P016 = 2 except that the inverter will only attempt to restart the motor in the direction of the requested setpoint. The motor is prevented from ‘rocking’ backwards and forwards during the initial frequency scan. Note: For MIDI MASTER units, it is recommended that P018 is set to ‘1’ if P016 is set to any value other than zero. This will ensure correct restarting on occasions when the inverter fails to re–synchronise on the initial attempt.

[1] 2 = Discontinuous smoothing. This provides a fast unsmoothed response to STOP commands. Note: P004 must be set to a value > 0.0 for this parameter to have any effect. P018 • Automatic restart after fault 0 – 1 Automatic restart after fault: [0] 0 = Disabled 1 = The inverter will attempt to restart up to 5 times after a fault. If the fault is not cleared after the 5th attempt, the inverter will remain in the fault state. P021 • Minimum analogue frequency 0 – 650.00 Frequency corresponding to the lowest analogue input value, i.e. (Hz) [0.00] 0 V/0 mA or 2 V/4 mA, determined by P023. This can be set to a higher value than P022 to give an inverse relationship between analogue input and frequency output (see diagram in P022). P022 • Maximum analogue frequency 0 – 650.00 Frequency corresponding to the highest analogue input value, i.e. 10 V or (Hz) [50.00] 20 mA, determined by P023. This can be set to a lower value than P021 to give an inverse relationship between analogue input and frequency output. i.e. f P021 P022 P022 P021 V / � P023 • Analogue input type 0 – 2 Sets analogue input type, depending on the position of switch SW1: [0] 0 V – 10 V P023 = 0 WARNING V 0 mA – 20 mA Setting P023 = 2 with no 2 V – 10 V P023 = 1 connections between X1.3 SW1 4 mA – 20 mA and X1.4 (MIDI MASTER) 2 V * – 10 V or X501.3 and X501.4 P023 = 2 � 4 mA * – 20 mA (MICRO MASTER) will cause the inverter to run * The inverter will come to a controlled stop if V < 1 V or �� < 2 mA. immediately. Notes: (1) Setting P023 = 2 will not work unless the inverter is under full local control (i.e. P910 = 0 or 4). (2) For failsafe operation (e.g. to protect against a break in the control wire), select current input. P024 • Analogue setpoint addition 0 – 2 If the inverter is not in analogue mode (P006 = 0 or 2), setting this [0] parameter to ‘1’ causes the analogue input value to be added. 0 = No addition 1 = Addition of the analogue setpoint to the fixed frequency or the motor potentiometer frequency. 2 = Scaling of digital/fixed setpoint by analogue input in the range 0 – 100%. Note: By selecting a combination of reversed negative fixed frequency settings and analogue setpoint addition, it is possible to configure the inverter for ‘centre zero’ operation with a +/–5 V supply or a 0 – 10 V potentiometer so that the output frequency can be 0 Hz at any position, including the centre position.

It is controlled [5.00] via the JOG button or with a non–latching switch on one of the digital inputs (P051 to P055). If jog right is enabled (DINn = 7), this parameter controls the frequency at which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency. P032 • Jog frequency left (Hz) 0 – 650.00 If jog left is enabled (DINn = 8), this parameter controls the frequency at [5.00] which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency. P033 • Jog ramp up time (seconds) 0 – 650.0 This is the time taken to accelerate from 0 Hz to maximum frequency [10.0] (P013) for jog functions. It is not the time taken to accelerate from 0 Hz to the jog frequency. If DINn = 16 (see P051 – P055) then this parameter can be used to override the normal ramp up time set by P002. P034 • Jog ramp down time (seconds) 0 – 650.0 This is the time taken to decelerate from maximum frequency (P013) to [10.0] 0 Hz for jog functions. It is not the time taken to decelerate from the jog frequency to 0 Hz. If DINn = 16 (see P051 – P055) then this parameter can be used to override the normal ramp down time set by P003.

Siemens plc 1996 G85139–E1720–U325–B  36 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions Parameter Function Range Description / Notes [Default] P061 Selection relay output RL1 0 – 13 [6] 3 Value Relay function Active 0 No function assigned (relay not active) Low 1 Inverter is running High 2 Inverter frequency 0.0 Hz Low 3 Motor running direction right High 4 External brake on (see parameters P063/P064) Low 5 Inverter frequency less than or equal to minimum Low frequency 1 6 Fault indication Low 7 Inverter frequency greater than or equal to setpoint High 2 8 Warning active Low 9 Output current greater than or equal to P065 High 2 10 Motor current limit (warning) Low 2 11 Motor over temperature (warning) Low 12 Closed loop motor LOW speed limit High 13 Closed loop motor HIGH speed limit High 1 Inverter switches off (see parameter P930 and section 6). 2 Inverter does not switch off (see parameter P931). 3 ‘Active low’ = relay OFF. ‘Active high’ = relay ON. Note: If the external brake function is used (P061 or P062 = 4) and additional slip compensation is used (P071 > 0), minimum frequency must be less than 5 Hz (P012 < 5.00), otherwise the inverter may not switch off reliably. P062 Selection relay output RL2 0 – 13 Sets the relay function, output RL2 (terminals 19/20) (refer to the table in [8] P061). P063 External brake release delay 0 – 20.0 Only effective if the relay output is set to control an external brake (seconds) [1.0] (P061 = 4). In this case when the inverter is switched on, it will run at the minimum frequency for the time set by this parameter before releasing the brake control relay and ramping up (see illustration in P064). P064 External brake stopping time 0 – 20.0 As P063, only effective if the relay output is set to control an external (seconds) [1.0] brake. This defines the period for which the inverter continues to run at the minimum frequency after ramping down and while the external brake is applied. f ON OFF f min t t t A = Brake Applied P063 P064 B = Brake removed B A A Notes: (1) Settings for P063 and P064 should be slightly longer than the actual time taken for the external brake to apply and release respectively. (2) Setting P063 or P064 to too high a value, especially with P012 set to a high value, can cause an overcurrent warning or trip as the inverter attempts to move a locked motor shaft. P065 Current threshold for relay (A) 0 – 99.9 This parameter is used when P061 = 9. The relay switches on when the [1.0] motor current is greater than the value of P065 and switches off when the current falls to 90% of the value of P065 (hysteresis). Siemens plc 1996  G85139–E1720–U325–B 37 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions Parameter Function Range Description / Notes [Default] P070 Braking Resistor Duty Cycle 0 – 4 0 = 5% (as for previous MICRO MASTERS) (MICRO MASTER only) [0] 1 = 10% 3 = 50% 2 = 20% 4 = 100% (i.e. continuous) WARNING: Standard braking resistors for the MICRO MASTER are designed for the 5% duty cycle only. Do not select higher duty cycles unless suitably rated resistors are being used to handle the increased power dissipation. P071 • Slip compensation (%) 0 – 200 The inverter can estimate the amount of slip in an asynchronous motor at [0] varying loads and increase its output frequency to compensate. 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. Over–compensation can cause instability. P072 • Slip limit (%) 0 – 500 This limits the slip of the motor to prevent ‘pull–out’ (stalling), which can [250] occur if slip is allowed to increase indefinitely. When the slip limit is reached, the inverter reduces the frequency until the level of slip is below the limit. P073 • DC injection braking (%) 0 – 250 This stops the motor by applying a DC current. This causes heat to be [0] generated in the motor rather than the inverter and holds the shaft stationary until the end of the braking period. Braking is effective for the period of time set by P003. The DC brake can be activated using DIN1 – DIN5 (see P051 – P055). 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 heat in the motor. P074 • Motor derating curve as 0 – 3 Self–cooling fan ventilated motors tend to overheat at low speeds. This is temperature protection [0] because the current (and therefore the heat) generated in the motor is the same, but the rate of heat dissipation from the motor is only about 25% of normal when the fan is not running. It may be necessary, therefore, to derate a self–cooled motor at low speeds using this parameter. The 2 internal I t calculation allows a brief overload period (max. 1 minute at 150% of reduced value). The following derating curves are available: P074 = 0 P074 = 1 P074 = 3 P074 = 2 100% I N 50% I N 50% F 100% F 150% F N N N I = Nominal motor current (P083) N F = Nominal motor frequency (P081) N 0 = No derating. Suitable for motors with separately powered cooling or no fan cooling which dissipate the same amount of heat regardless of speed. 1 = Normally suitable for 2–pole motors which generally have better cooling due to their higher speeds. The inverter assumes that the motor can dissipate full power at = > 50% nominal frequency. 2 = Try this setting if the motor still runs too hot with P074 set to ‘3’. 3 = Suits most motors, full nominal power delivered at = > 100% nominal frequency. Siemens plc 1996 G85139–E1720–U325–B  38 07.96 English MICRO MASTER and MIDI MASTER Operating Instructions Parameter Function Range Description / Notes [Default] P075 • Braking resistance (Ω) 0/50 – 250 An external braking resistor can be used to ‘dump’ the power generated (MICRO MASTER only) [0] by the motor, thus giving greatly improved braking capabilities. It MUST NOT be less than 50Ω (85Ω for 3 AC 400 V inverters) or the inverter will be damaged. Several purpose made resistors are available to cater for all MICRO and MIDI MASTER variants. WARNING: Take care if an alternative resistor is to be used as the pulsed voltage applied by the inverter can destroy ordinary resistors. Set P075 = 0 if an external braking resistor is not required. P076 • Pulse frequency 0 – 10 Sets the pulse frequency (from 2.44 to 16 kHz) and the PWM mode. If [0 or 4] 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. Previously used modulation modes 1 and 2 are now combined and selected automatically by the inverter. Mode 3 randomises the pulse frequency to avoid resonance and can be used to reduce noise in the motor. 0/1 = 16 kHz 2/3 = 8 kHz 4/5 = 4 kHz 6/7 = 2.44 kHz 8 = 8 – 16 kHz modulation mode 3 9 = 4 – 8 kHz modulation mode 3 10 = 2.44 – 4 kHz modulation mode 3 Note: When P076 = 0/1, the display of the current at frequencies below 10 Hz is less accurate. Certain inverters may have their maximum continuous current (100%) derated if the value of P076 is changed from the default value to another value: Model P076 = 0 or 1 2 or 3 8 9 MM400/3 60% 80% 80% 90% MM550/3 60% 80% 80% 90% All MIDI 50% 90% 50% 90% MASTERS Notes: (1) If P076 = 4, 5, 6, 7 or 10 then derating does not occur on these inverters. (2) Changing the value of P076 may cause the values of P083 and/or P086 to be reduced automatically if these exceed the maximum derated value.

One of three modes can be selected: 0 = Linear voltage/frequency Use this curve for synchronous motors or motors connected in parallel. 1 = Flux Current Control (FCC) In this mode the inverter makes real–time calculations of the required voltage by modelling the behaviour of the motor. This allows it to adjust the motor for full flux in all conditions. 2 = Quadratic voltage/frequency relationship This is suitable for pumps and fans.

[100] For many applications it is necessary to increase low frequency torque. This parameter sets the start–up current at 0 Hz to adjust the available torque for low frequency operation. Range 0 – 250% of the motor current rating. WARNING: If P078 is set too high, overheating of the motor and/or an overcurrent trip (F002) can occur. P079 • Starting boost (%) 0 – 250 For drives which require a high initial starting torque, it is possible to set [0] an extra voltage increase by boosting the starting current by 0 – 250% of the nominal motor current. This increase is only effective during initial start up and until the frequency setpoint is reached. Note: This increase is in addition to P078. P081 Nominal frequency for motor (Hz) 0 – 650.00 [50.00] P082 Nominal speed for motor (RPM) 0 – 9999 [III] These parameters must be set for the motor used.

P085 Nominal power for motor (kW) 0 – 50.0 [III] P086 • Motor current limit (%) 0 – 250 With this parameter the motor current can be limited and overheating of [150] the motor prevented. If the set value is exceeded, the output frequency is reduced until the current falls below this limit. During this process the display flashes as a warning indication. The inverter does not trip, but you can make it trip by using the relay in conjunction with P074 to provide motor protection. MIDI MASTER inverters only: The maximum value of P086 is reduced when a quadratic voltage/frequency is selected (P077 = 2). In this case the value of P086 will be limited automatically and its value may change from that entered. If P077 is reset to 0 or 1 then the value of P083 may also change.

The relay will not operate unless it is set to a general fault (P061 = 6). If P061 = 11 then the relay operates as a warning if either the internal PTC gets hot (indicating high heatsink temperature) or if P074 is activated. Warning code 005 is written to P931 and the display flashes. Note that if the internal PTC gets too hot, the inverter will trip and F005 will be displayed. P088 Automatic calibration 0 – 1 The stator resistance is used in the inverter’s current monitoring calculations. [0] This function allows the inverter to perform an automatic measurement of stator resistance, stores it in P089 and then resets P088 to ‘0’. If the measured resistance is too high for the size of inverter (e.g. motor not connected or unusually small motor connected), the inverter will trip (fault code F188) and will leave P088 set to ‘1’. If this happens, set P089 manually and then set P088 to ‘0’. P089 • Stator resistance (Ω) 0.01 – Can be used instead of P088 to set the stator resistance manually. The 100.00 value entered should be the resistance between any two phases. [III] Note: If the value of P089 is too high then an overcurrent trip (F002) may occur.

P093 • Timeout (seconds) 0 – 240 This is the maximum permissible period between two incoming data [0] telegrams. This feature is used to turn off the inverter in the event of a communications failure. Timing starts after a valid data telegram has been received and if a further data telegram is not received within the specified time period, the inverter will trip and display fault code F008. Setting the value to zero switches off the control.

The last error that occurred is stored in parameter P930. e.g. ‘0004’ indicates that the last error was F004. Fault Code Cause Corrective Action F001 Overvoltage Check whether supply voltage is within the limits indicated on the rating plate. Increase the ramp down time (P003) or apply braking resistor (option). Check whether the required braking power is within the specified limits. F002 Overcurrent Check whether the motor power corresponds to the inverter power. Check that the cable length limits have not been exceeded. Check motor lead and motor for short–circuits and earth faults. Check whether the motor parameters (P081 – P086) correspond with the motor being used. Check the stator resistance (P089). Increase the ramp–up time (P002). Reduce the boost set in P078 and P079. Check whether the motor is obstructed or overloaded. F003 Overload Check whether the motor is overloaded. Increase the maximum motor frequency if a motor with high slip is used. F004 Overheating of motor Check whether the motor is overloaded. (monitoring with PTC) Check the connections to the PTC.

There are three routes by which the manufacturer/assembler can demonstrate compliance: 1. Self–Certification This is a manufacturer’s declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards which have been officially published in the Official Journal of the European Community can be cited in the manufacturer’s declaration. 2. Technical Construction File A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organisation. This approach allows the use of standards which are still in preparation. 3. EC Type–Examination Certificate This approach is only applicable to radio communication transmitting apparatus. The MICRO and MIDI MASTER units do not have an intrinsic function until connected with other components (e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive. However, full details are provided below of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in section 2.1. Three classes of EMC performance are available as detailed below. Note that these levels of performance are only achieved when using the default switching frequency (or less) and a maximum motor cable length of 25 m. Class 1: General Industrial Compliance with the EMC Product Standard for Power Drive Systems IEC 22G–WG4 (Cv) 21 for use in Second Environment (Industrial) and Restricted Distribution. Note Manufacturers/assemblers of electrical apparatus incorporating power drive systems who need to certify compliance with the EMC directive to their customers will need to produce a Technical Construction File (TCF) underwritten by a ‘Competent Body’ until the above power drive systems standard (IEC 22G–WG4 (Cv) 21) has been officially published in the Official Journal of the European Community. Once this has occurred, the self–certification route to compliance will be possible.
