VFD-F Series

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.

In the following chart

T1: enter sleep process time (Pr.11-07)

T2: motor switch delay time during fixed amount circulation (Pr.11-05)

T3: motor switch delay time (Pr.11-04)
