SIEMENS MICROMASTER MICROMASTER Vector 6SE32 MIDIMASTER Vector 6SE32 Default Parameters: The MICROMASTER Vector (MMV) and the MIDIMASTER Vector (MDV) are a range of frequency inverters for controlling the speed of three phase AC induction motors. Step 1 Connecting up the MMV and MDV 230V Single Phase 400V Three Phase Press this green button (RUN button) to start the motor. Forward/ reverse While the motor is 'STOP' turning, press this UP button and watch as the motor turns faster and the value in the display increases. It will keep increasing until it reaches 50 Hz Hz. Jog P This Thisisisthe the 'STOP STOP' button button. When the inverter reaches 50Hz output, press this DOWN 'DOWN' button button and watch the motor speed and display value decrease. At any time, press the 'STOP' button and watch the motor stop. Step 3 Delta connection for 230V 3 phase Star connection for 400V 3 phase Note: Motors above 11kW are usually configured 400V Delta / 690V Star. In this case the motor should be connected in Delta. Caution: Before installing and putting this equipment into operation, please read the Operating Instructions Manual for Safety Precautions and Warnings MIDIMASTER Vector (MDV) The MDV electrical installation section of the Operator Instructions Manual shows the position of the terminals used to connect the power and the motor. 1 2 3 4 5 6 P051 = 1 P052 = 2 P053 = 6 P054 = 6 P055 = 6 P356 = 6 ON right ON left Fixed frequency 3 Fixed frequency 2 Fixed frequency 1 Fixed frequency 6 18/19/20 P061 = 6 P062 = 8 21/22 Fault identification Warning active 5 6 7 8 16 17 Output Relays 1 2 Changing the speed of the motor The default output frequency of the drive is 5Hz (see Hints and Tips to convert this to RPM). This speed will probably be too low for most applications and a speed change may be required. The following steps will allow you to change the preset value of the inverter output to the required speed. Getting Started Digital input Terminal Parameter Default Fault Codes: Step / Action Display F001 F002 F003 F004 F005 Press the 'P' button to access the parameter settings.

(This number can be any number between 0 and 50Hz - default.) 035.0 Press the 'P' button to store the new value. P005 For further Technical Support Information, and to submit your suggestions for improvements, see our Web Site: Press the P000 http://www.con.siemens.co.uk button until the display reads P000. Press the 'P' button to exit the parameterisation procedure. The display will alternate between the output frequency and the frequency set point. 000.0 035.0 The required speed has now been stored. This method is used to access all parameters. The drive can now be started by pressing the 'RUN' button. It will ramp up to the frequency held in parameter P005 and remain there. To stop the drive press the 'STOP' button, the drive will then ramp down to 0Hz output.

This is achieved by varying the voltage applied to the analogue input. Connect the potentiometer to the control terminals shown below. Starting and stopping of the motor may be achieved by connecting a switch to the digital input terminals shown. The following parameter settings are required P006 Set to 1 to allow analogue input P007 Set to 0 to enable control via digital input Hints and Tips Commissioning MICROMASTER Vector / MIDIMASTER Vector Display parameters Basic parameters Select display via P001 Ramp-up time P002 0-650 sec.

The following diagram indicates the location of the information and the parameters which should be entered.

Parameters P000 to P009 can always be read or set. Access to all other parameters is controlled by the contents of P009. The factory default value is '0' which only allows access to P000 to P009. Changing its value to ‘3' allows all parameters to be accessed permanently. See Operator Manual for the function of other values of P009. In case there are problems with the parameter settings and you wish to start again, change P944 to '1'. This will reset to the default settings. The value displayed in P000 is the output frequency of the inverter, this is the default setting but it can be changed by altering the value in P001. For example, changing P001 to a value of '5' will cause the inverter to display the RPM of the motor in P000. See the Operator Manual for other settings of P001. The default value (0) of parameter P006 ensures that the drive runs at the frequency set in P005. In order to control the output frequency by an analogue input signal, the value of P006 should be set to '1'. For other methods of control using P006, see the Operator Manual. DIP selection switches are used to select a range of 0-10V or 0-20mA for the analogue input. See the Operator Manual for more information. An F002 fault is often caused by either too short a ramp time or too much voltage boost. An increase in the values in P002 will increase the ramp time. Alternatively lower the values in P078 and P079 to reduce the voltage boost. Please note that if P078 falls below '100' (default value for MMV) then the motor may under-perform at low frequencies. An F001 fault is often caused by attempting to stop the motor too quickly - increasing the value in P003 (ramp-down time) will reduce this possibility. If the display flashes during operation, the drive is registering a warning. Check P931 for the cause.
