Init Magnet Pole Estimation
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.
When you use High Frequency Injection Auto-Tuning, the drive will automatically set this value.
Note:
• Set n8-35 = 1 [Initial Pole Calculation Method = High Frequency Injection] to enable this
parameter.
• When A1-02= 6 [AOLV/PM] and you do High Frequency Injection Auto-Tuning, the drive
automatically sets this parameter .
• Set n8-41 [HFI P Gain] to adjust the responsiveness for initial motor magnetic pole calculation
when A1-02 = 5, 7 [OLV/PM, CLV/PM].
