simultaneously.
1: IM V/F control + MI7 one-phase pulse input: you can use the MI7 one-phase pulse input for
closed-loop speed control.
2: IM/PM space vector control: gets the optimal control by auto-tuning the motor parameters.
5: IM FOC sensorless: IM field-oriented sensorless vector control.
 If you use MI7 single-phase pulse input as speed feedback, apply it for VFPG closed-loop
control.
 If you use 1: IMVFPG control mode along with MI7 as speed feedback, you also need to set
Pr.10-00 = 5 and Pr.10-02 = 5.
 When Pr.00-10 = 0 and you set Pr.00-11 to 0, the V/F control diagram is as follows:
