What Can Cause an Altivar Drive to Fail During Auto Tune?

1. Motor Not Connected

   • Verify that the motor is properly connected to the drive.
   • Check for any open circuits or disconnected motor leads.

2. Motor Disconnect Switch Open

   • If a motor disconnect switch or contactor is installed between the drive and the motor, ensure it is closed during the Auto Tune process.
   • The drive must be able to communicate electrically with the motor to complete Auto Tune successfully.

3. Incorrect Motor Parameters

   • Confirm that all motor nameplate data entered in the drive matches the motor's actual specifications.
   • Verify parameters such as:
     • Rated voltage
     • Rated current
     • Rated frequency
     • Rated speed (RPM)
     • Rated power

4. Motor Temperature Too High

   • Auto Tune should be performed with the motor at or near ambient temperature.
   • If the motor is hot from recent operation, allow it to cool before running Auto Tune again.
