Startup with MWA21A option

WARNING

Electric shock from capacitors that have not been fully discharged.
Severe or fatal injuries.
  • Disconnect the inverter from the power. Observe the minimum switch-off time after disconnection from the supply system:
    • 1 minute
  1. Remove the MOVIMOT® inverter from the connection box.
  2. Check whether the MOVIMOT® drive is installed correctly both mechanically and electrically.
    • Refer to chapters "Mechanical Installation" and "Electrical Installation".
  3. Set DIP switch S1/1 of the MOVIMOT® inverter to "ON" (= address 1).
  4. Set the minimum frequency fmin using the switch f2.

Meaning

Activated

Activated

  • Both directions of rotation are enabled.

Activated

Not activated

  • Only CW rotation is enabled.
  • Setpoint input for CCW rotation will stop the drive.

Not activated

Activated

  • Only CCW rotation is enabled.
  • Setpoint input for CW rotation will stop the drive.

Not activated

Not activated

  • The device is inhibited or the drive is stopped.

  1. Place the MOVIMOT® inverter onto the connection box and screw it in place.
  2. Set the required maximum speed using setpoint potentiometer f1 of the MOVIMOT® inverter.

  3. NOTICE! Loss of the specified degree of protection if the screw plugs on the f1 setpoint potentiometer and the X50 diagnostic interface are not installed or not installed correctly. Damage to the MOVIMOT® inverter. Make sure the screw plug of the setpoint potentiometer has a seal and screw it in.
  4. Select the signal type for the analog input (terminals 7 and 8) of the MWA21A option using switches S1 and S2.

  1. Switch on the DC 24 V control voltage and the line voltage.
  2. Enable the MOVIMOT® drive. This means applying 24 V to terminal 4 (CW rotation) or terminal 5 of the MWA21A option.
