• Before you do Rotational Auto-Tuning to prevent drive malfunction, uncouple the motor from the load. If you do Rotational Auto-Tuning with the motor connected to a load that is more than 30% of the motor duty rating, the drive will not correctly calculate the motor parameters and the motor can operate incorrectly.

  • When the load is 30% or less of the motor duty rating, you can do Auto-Tuning with the motor connected to a load.

  • Make sure that the motor magnetic brake is released.

  • Make sure that external force from the machine will not cause the motor to rotate.
