OverExcBr Harmonics
Selection
Sets the function that injects harmonic signals during overexcitation deceleration.
0
(0, 1)
Enable this parameter to set a shorter deceleration time.
Note:
•
If you frequently use overexcitation deceleration on a motor, the motor loss will increase the risk of burn damage.
•
When you set this parameter to
1
, the motor can make a loud excitation sound during overexcitation deceleration. If the excitation
sound is unwanted, set this parameter to
0
to disable the function.
0 : Disabled
1 : Enabled
The drive injects harmonic signals at the time of overexcitation deceleration. You can decrease the deceleration
time because motor loss increases.

n3-21
(0579)
OverExcBr Current Level
Sets the upper limit of the current that is suppressed at the time of overexcitation deceleration as a
percentage of the drive rated current.
100%
(0 - 150%)
If flux saturation during Overexcitation Deceleration makes the motor current become more than the value set in
this parameter, the drive will automatically decrease the overexcitation gain. If
oC [Overcurrent]
,
oL1 [Motor
Overload]
, or
oL2 [Drive Overloaded]
occur during overexcitation deceleration, decrease the setting value.
If repetitive or long overexcitation deceleration cause the motor to overheat, decrease the setting value.

n3-23
(057B)
OverExcBr Operation
Sets the direction of motor rotation where the drive will enable overexcitation.
1
(1 - 3)
1 : Enabled@Both directions
2 : Enabled@FW direction
3 : Enabled@REV direction
Note:
When
n3-23 = 2, 3
, the drive enables overexcitation only in the direction of motor rotation in which a regenerative load is applied.
Increased motor loss can decrease
ov [Overvoltage]
faults.
◆
n5: FEED FORWARD CONTROL
Feed forward control increases the responsiveness of acceleration and deceleration as specified by the speed
reference.
Increase the values set in
C5-01 and C5-03 [ASR PGain 1 and ASR PGain 2]
to apply feed forward control to
machines that have low rigidity and are possible to have hunting and vibration or to machines that have a large
quantity of inertia. Refer to
for more information about parameters related to feed forward control.
Set
A1-02 = 6 [Control Method = PM AOLVector]
to enable feed forward control.
Note:
•
You cannot use feed forward control to increase responsiveness in applications where you apply loads externally during run at constant
speed.
•
You cannot use feed forward control with motor 2.
