12.10 n: Special Adjustment
YASKAWA SIEPC71061737D GA800 Drive Technical Reference 1025
Sets the length of time that the pull-in current flows when the drive detects the motor magnetic pole of the rotors.
Note:
If the motor oscillates at the time of the polar attraction, increase the value in 0.5 s increments. If you set the value too high, the drive will
detect oL2 [Drive Overload].
■ n8-11: Observer Calculation Gain 2

Observer Calculation Gain 2
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
Determined by n8-72
(0.0 - 1000.0)
Note:
When n8-72 = 0 [Speed Estimation Method Select = Method 1], the default value is 50.0. When n8-72 = 1 [Method 2], the default value is
150.0.
