After power supply of motor is not from AC drive, the motor will coast to stop according to
loading characteristics. Users need to set 11-06 motor switch frequency and 11-04 delay
time of circulation control according to actual situation to make rotor speed equals to
commercial frequency.

This parameter determines frequency that motor runs by commercial power during fixed
amount circulation (11-01=02)/fixed amount control (11-01=03). This parameter should be
greater than commercial frequency. If output frequency of AC drive attains to motor switch
frequency, it means that even motor runs in full speed it can’t make detection value of PID
control attains to target value. Therefore, the power supply of the motor needs to be
changed from AC drive to commercial power. AC drive runs with the next motor and makes
the detection value close to target.
