DIRECTION OF ROTATION OF THE MOTOR
Check the direction of rotation of the motor.
Note :
In the crane application,
- the forward direction (positive) must be the UP direction.
- the reverse direction (negative) must be the DOWN direction.
This is important because the torque memory uses the positive
direction in starts.
- Press ACT to get the status row visible.
- Increase the speed reference from zero to a small value by
pressing
REF and then the arrow keys ( , , or ).
- Press to start the motor.
- Check that the motor is running in the desired direction.
- Stop the motor by pressing
.

To change the direction of rotation of the motor:
- Disconnect mains power from the drive, and wait 5 minutes for the
intermediate circuit capacitors to discharge. Measure the voltage
between each input terminal (U1, V1 and W1) and earth with a
multimeter to ensure that the frequency converter is discharged.
- Exchange the position of two motor cable phase conductors at the
motor terminals or at the motor connection box.
- Verify your work by applying mains power and repeating the check
as described above.
