Delta C2000 Series User Manual page 258

This parameter determines the control method of the AC motor drive:
0: (IM V/f control): user can design proportion of V/f as required and can control multiple motors
simultaneously.
1: (IM V/f control + Encoder): user can use optional PG card with encoder for the closed-loop
speed control.
2: (IM Sensorless vector control): get the optimal control by the auto-tuning of motor
parameters.
3: (IM FOC vector control+ encoder): besides torque increases, the speed control will be more
accurate (1:1000).
4: (PM FOC vector control + Encoder): besides torque increases, the speed control will be more
accurate (1:1000).
5: FOC Sensorless: IM field oriented sensorless vector control
6: PM Sensorless (PM field oriented sensorless vector control)
7: IPM Sensorless (Interior PM field oriented sensorless vector control)
When 00-10=0, and set Pr.00-11 to 0, the V/F control diagram is shown as follows.
