n2: Speed Feedback Detection Control Function
Use n2 parameters to configure the Speed Feedback Detection Control function operation.
n2-01
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.

(AFR) Time Constant
Sets the AFR time constant 1.

Sets the AFR time constant 2. Increase the
setting if overvoltage occurs during sudden load
changes or the speed overshoots during fast
acceleration.

n3: High-Slip Braking / Overexcitation Deceleration
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.
1 to 20

588
n3-02
High-Slip Braking
Current Limit
Sets the current limit during HSB. Higher n3-02
settings will shorten motor stopping times but
increase the motor current, and therefore motor
heating.

n3-03
High-Slip Braking
Dwell Time at Stop
Sets the time the drive will run with minimum
frequency (E1-09) at the end of deceleration.
If this time is set too low, the machine inertia
can cause the motor to rotate slightly after HSB
completion.
0.0 to
10.0

58A
n3-04
High-Slip Braking
Overload Time
Sets the time required for an HSB overload
fault (OL7) to occur when the drive output
frequency does not change during an HSB stop.
This parameter does not typically require
adjustment.
30 to
1200
40 s A

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.
