3.
Start the drive by energising
the Start Input (T33)
4.
The contactor closes and an autotune is performed (it takes 10 – 60 seconds). When
complete, the drive's contactor opens.
Turn off the Start Input (T33).
5.
Save the parameters. See section 3.1.2.
4.7 Motor rotational checks
Disconnect the motor from the gear box and machine before starting these running checks.
1.
Reduce the current limit.
As an added precaution, restrict the available current to the drive by reducing the
Current Limit to just enough current to turn the motor (usually 5 to 10%).
2.
Check the speed potentiometer operation. Monitor the Ramp Input to check the operation of
the speed potentiometer. Leave the reference at zero after checking for correct operation.
3.
Start the drive.
Energise the Start Input (T33) to start the drive. Check the field voltage at the F+ and F-
terminals. When the motor is cold, you will measure less than the rated field voltage
4.
Confirm the field current matches the nameplate data.
5.
Increase the potentiometer setting until the motor turns slowly.
Check motor rotation. If it is turning backwards, stop, turn off ALL power to the drive and
swap the field leads (F+ and F-). Recheck after changes.
6.
Slowly bring the motor to full speed.
Check the voltage on the A+ and A- terminals as you slowly bring the motor up to full speed.
