Note:

Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
When A1-02= 6 [Control Method Selection = AOLV/PM] and you do High Frequency Injection Auto-Tuning, the drive automatically sets this parameter .
Set n8-41 > 0.0 for IPM motors.

Set this parameter as follows.

If there is oscillation or hunting, decrease the setting in units of 0.5.
When it is necessary to track load changes, increase the setting in units of 0.5.
