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.

Hunting Prevention Time
Constant
Sets the time constant used for hunting prevention. 0 to 500

n1-05
Hunting Prevention Gain
while in Reverse
Sets the gain used for Hunting Prevention.
When set to 0, the gain n1-02 is used for operation in reverse
direction.

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.
0.00 to
10.00
<8> − A − 584 240
Adjust the setting by 0.05 units at a time, while
checking the response.

Speed Feedback Detection
Control (AFR) Time Constant Sets the AFR time constant 1. 0 to 2000 50 ms − A − 585 241
n2-03
Speed Feedback Detection
Control (AFR) Time Constant
2
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
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 5% A − − 588 241
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.
100 to 200 150% A − − 589 242
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 1.0 s A − − 58A 242
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 − − 58B 242
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.

High-Slip Suppression
Current Level
If overcurrent or overload occur during high-slip deceleration,
reduce the high-slip suppression current level. Set as a
percentage of the drive rated current.

n6: Online Tuning of Motor Line-to-Line Resistance
Use n6 parameters to adjust the motor line-to-line resistance while the drive is online.
n6-01
Line-to-Line Motor
Resistance Online Tuning
Tunes the line-to-line motor resistance continuously during
operation.
