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.

5.0

(-20.0 - +20.0)

Note:

Set n8-35 = 1 [Initial Pole Calculation Method = High Frequency Injection] to enable this parameter.
The drive automatically calculates this value when High Frequency Injection Auto-Tuning completes successfully.

Used when n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection]. Sets the responsiveness for initial motor magnetic pole calculation. Set this parameter to a positive value for an ordinary monitor. When you use High Frequency injection Tuning, it will automatically set this parameter.
