Hunting
Prevention Gain
Setting
Sets the gain for the Hunting
Prevention Function. If the motor
vibrates while lightly loaded and
n1-01 = 1, increase the gain by 0.1
until vibration ceases. If the motor
stalls while n1-01 = 1, decrease the
gain by 0.1 until the stalling ceases.

n3-13 Overexcitation
Deceleration Gain
Applies a gain to the V/f pattern
during deceleration (L3-04 = 4).
Returns to normal values after
ramp to stop or at re-acceleration.
To increase the braking power of
overexcitation, increase the gain by
1.25 to 1.30.
