n1: Hunting Prevention
Use n1 parameters to configure hunting prevention operation.

If the motor vibrates while lightly loaded, Hunting Prevention
may reduce the vibration.

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.

n2: Speed Feedback Detection Control Function
Use n2 parameters to configure the Speed Feedback Detection Control function operation.

Speed Feedback Detection
Control (AFR) Gain
Sets the internal speed feedback detection control gain in the
automatic frequency regulator (AFR).
This parameter does not typically require adjustment. Adjust
this parameter as follows:
If hunting occurs, increase the set value.
If response is low, decrease the set value.

n3: High-Slip Braking
Use n3 parameters to configure the high-slip braking function.
n3-01
High-Slip Braking
Deceleration Frequency
Width
Sets the output frequency reduction step width when the drive
stops the motor using high-slip braking (HSB).
If Overvoltage (ov) faults occur during HSB, this parameter
may need to be increased.
