Carrier Frequency
Reduction Off Delay
Time
Sets the time that the drive continues
running with reduced carrier frequency
after the carrier reduction condition is gone.
Setting 0.00 s disables the carrier frequency
reduction time.
L8-41
High Current Alarm
Selection
0: Disabled
1: Enabled. An alarm is triggered at output
currents above 150% of drive rated current.

Hunting Prevention
Selection
0: Disabled
1: Enabled
n1-02
Hunting Prevention
Gain Setting
If the motor vibrates while lightly loaded,
increase the gain by 0.1 until vibration
ceases. If the motor stalls, decrease the gain
by 0.1 until the stalling ceases.
n1-03
Hunting Prevention
Time Constant
Sets the time constant used for Hunting
Prevention.
n1-05
Hunting Prevention
Gain while in Reverse
Sets the gain used for Hunting Prevention.
If set to 0, the gain set to n1-02 is used for
operation in reverse.
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.
n3-21
High-Slip Suppression
Current Level
Sets output current level at which the drive
will start reducing the overexcitation gain
in order to prevent a too high motor slip
during Overexcitation Deceleration. Set as
a percentage of the drive rated current.
n3-23
Overexcitation
Operation Selection
0: Enabled in both directions
1: Enabled only when rotating forward
2: Enabled only when in reverse
