 Determines the AC motor drive control method.
0: You can set the V/F ratio as required and control multiple motors simultaneously.
1: You can use a PG card with an encoder for closed-loop speed control.
2: Use auto-tuning for optimal settings of the control parameters.
3: To increase torque and the accuracy of the speed control (1:1000).
8: To increase torque and the accuracy of the speed control (1:1000). This setting is for use only with
permanent magnet motors. The other settings are for use with induction motors.
