(A1-02 = 0 or 1).
1. Select the Auto-Tuning Menu. Then, select “Term Resistance” in the “Tuning Mode Sel” parameter (T1-01 = 2).
2. Set the motor output power (T1-02) and motor rated current (T1-04) obtained from the motor nameplate information.
After entering all of the motor parameters press the UP key to display “0Hz/ 0.00A Tuning Ready?”.
3. Press the RUN key to start Auto-Tuning. The Drive will set the required motor parameter automatically while
energizing the motor (without rotation) for approximately 30 seconds. If the Auto-Tuning is successful, the Digital
Operator keypad will display “Tune Successful”.
