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 (
- 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.
SPEED LIMITS AND ACCELERATION/DECELERATION TIMES
Set the minimum speed. This value will be used as the speed limit
in the reverse direction.
Set the maximum speed. This value will be used as the speed limit
in the forward direction.
Set the acceleration time 1.
Set the acceleration time 2.
