does not permit auto-tuning, set P.301 to 2 (static measurement) if motoring is running.
3. Sensorless vector control: Auto-tuning function can be used to enhance the control function.
Before setting P.300 to 3 or 4, first set the motor parameters or the auto-tuning function to
improve the control accuracy.
4. When P.300=1 and the mode of Close-loop V/F control (VF + PG) is selected, please make sure
that the motor poles P.303 is correct.

• When the motor can be fully separated from the load, select P.301=1. When the motor is
running, the motor parameter will carry out auto-tuning. Then press

panel for the inverter to automatically calculate the following parameter: P.308~P.312.
• When the motor cannot be fully separated from the load, select P.301=2. When the motor is
