Rated Slip Error

The motor nameplate data entered during Auto-Tuning is incorrect.

  • Make sure that the input motor nameplate data is correct.

  • Do Auto-Tuning again and correctly set the motor nameplate data.

Auto-Tuning did not complete in a pre-set length of time.

  • Examine and repair the motor wiring.

  • If the motor and machine are connected during Rotational Auto-Tuning, decouple the motor from the machinery.

The Auto-Tuning results were not in the applicable parameter setting range.

Rotational Auto-Tuning was done with a load that was more than 30% of the rating connected to the motor.

  • Disconnect the machine from the motor and do Rotational Auto-Tuning again.

  • If you cannot uncouple the motor and load, make sure that the load is less than 30% of the motor rating. If a mechanical brake is installed in the motor, release the brake during Rotational Auto-Tuning.
