3. Enter the type of Auto-Tuning to parameter T1-01.
4. Enter the motor nameplate data.
5. Start the Auto-Tuning process when prompted by the drive.
6. If Auto-Tuning was successfully performed, do a test run without the load and make any necessary parameter
adjustments.
7. If the test run was successful, do a test run with the load connected and make parameter adjustments if necessary.
