Speed Control Mode
Default: 0
Settings
0: IM V/F (IM V/F control)
2: IM / PM SVC (IM / PM space vector control)
 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.
2: IM sensorless vector control: get the optimal control by auto-tuning the motor parameters.
 When Pr.00-10 = 0 and you set Pr.00-11 to 0, the V/F control diagram is as follows:
