502 YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual
n3: High Slip Braking (HSB) and Overexcitation Braking
n5: Feed Forward Control
No. (Addr.) Name Description Setting Page
n3-01
(588H)
<50>
The default setting is determined by the values set to duty selection (C6-01) and the carrier frequency reduction selection (L8-38).
High Slip Braking Deceleration
Frequency Width
Sets the output frequency reduction step width for when the drive stops the motor using HSB.
Set as a percentage of the maximum output frequency. Increase this setting if overvoltage
occurs during HSB.
Default: 5%
Min: 1%
Max: 20%
303
n3-02
(589H)
High Slip Braking Current Limit
Sets the current limit during HSB as a percentage of the motor rated current.
Default:
<50>
Min: 100%
Max: 200%
304
n3-03
(58AH)
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.
Default: 1.0 s
Min: 0.0 s
Max: 10.0 s
304
n3-04
(58BH)
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.
Default: 40 s
Min: 30 s
Max: 1200 s
304
n3-13
(531H)
Overexcitation Deceleration Gain
Sets the gain applied to the V/f pattern during Overexcitation Deceleration (L3-04 = 4).
Default: 1.10
Min: 1.00
Max: 1.40
305
n3-14
(532H)
High Frequency Injection during
Overexcitation Deceleration
0: Disabled
1: Enabled
Default: 0
Min: 0
Max: 1
305
n3-21
(579H)
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.
Default: 100%
Min: 0%
Max: 150%
305
n3-23
(57BH)
Overexcitation Operation
Selection
0: Enabled in both directions
1: Enabled only when rotating forward
2: Enabled only when in reverse
Default: 0
Min: 0
Max: 2
305
No. (Addr.) Name Description Setting Page
n5-01
(5B0H)
<9> Default setting value is dependent on the drive model (o2-04) and the Drive Duty (C6-01).
<14> Default setting value is dependent on the motor code set to E5-01.
Feed Forward Control Selection
0: Disabled
1: Enabled
Default: 0
Min: 0
Max: 1
306
n5-02
(5B1H)
Motor Acceleration Time
Sets the time required to accelerate the motor at the rated torque from stop to rated speed.
Default:
<9> <14>
Min: 0.001 s
Max: 10.000 s
306
n5-03
(5B2H)
Feed Forward Control Gain
Sets the ratio between motor and load inertia. Lower this setting if overshoot occurs at the end
of acceleration.
Default: 1.00
Min: 0.00
Max: 100.00
