Initial Pole Detection
Response Gain
Sets the responsiveness for initial motor magnetic pole calculation when A1-02 = 6 [Control Method
Selection = AOLV/PM]. Set b3-61 > 0.0 for an ordinary IPM motor.
It is automatically set if High Frequency Injection Tuning is used.
Note:
• Set n8-35 = 1 [Initial Pole Calculation Method = High Frequency Injection] to enable this
parameter.
• Set n8-41 [HFI P Gain] to adjust the responsiveness for initial motor magnetic pole calculation
when A1-02 = 5 [OLV/PM].
