n3: Overexcitation Deceleration
Use n3 parameters to configure the Overexcitation Deceleration braking function.
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.
