 Determines the control mode of the AC motor drive:
0: IM V/F control: you can set the proportion of V/F as required and control multiple motors
simultaneously.
1: IM V/F control + Encoder pulse input: you can use the encoder for closed-loop speed control.
2: IM sensorless vector control: get the optimal control by auto-tuning the motor parameters.
3: IM FOC vector control+ Encoder: not only can increase torque, but also can increase the
accuracy of the speed control (1:1000).
4: PM FOC vector control + Encoder: not only can increase torque, but also can increase the
accuracy of the speed control (1:1000).
5: IM FOC Sensorless: IM field oriented sensorless vector control
7: IPM Sensorless: interior PM field oriented sensorless vector control
