Braking Features
395 DC Brake Time
DC Brake Time
Sets the amount of time DC brake current is “injected” into the motor.
When the active stop mode, P370/371 [Stop Mode n] = 2 “Ramp to Hold,” this
parameter is ignored and DC braking is applied continuously.
Functional in all motor control modes.

0.00 / 90.00
RW Real
396 DC Brake Ki
DC Brake Integral Gain
Sets the integral term used in the current regulator which controls the DC Brake
function.
Functional in all motor control modes.
Default:
Min/Max:
10.0
0.0 / 1000.0

397 DC Brake Kp
DC Brake Proportional Gain
Sets the proportional term used in the current regulator which controls the DC Brake
function.
Default:
Min/Max:
1000.0
0.0 / 10000.0
RW Real
398 DC Brk Vq Fltr
DC Brake Vq Filter
Sets the level of filtering used on the Vq signal when the active stop mode P370/371
[Stop Mode n] = 4 “DCBrkAutoOff.”
Default:
Min/Max:
250.0
50.0 / 2000.0
RW Real
399 DC Brk Vd Fltr
DC Brake Vd Filter
Sets the level of filtering used on the Vd signal when the active stop mode P370/371
[Stop Mode n] = 4 “DCBrkAutoOff.”
Default:
Min/Max:
250.0
50.0 / 2000.0

400 Fast Braking Ki
Fast Braking Integral Gain
Sets the integral term used in the speed regulator which controls the Fast Braking
function.
Functional in all motor control modes.
Default:
Min/Max:
0.10
0.00 / 10.00
RW Real
401 Fast Braking Kp
Fast Braking Proportional Gain
Sets the proportional term used in the speed regulator which controls the Fast Braking
function.
Functional in all motor control modes.
Default:
Min/Max:
0.0015
0.0000 / 10.0000
RW Real
402 Brake Off Adj 1
Brake Off Adjustment 1
When Fast Braking is the selected Stop Mode, this parameter sets the power sensitivity
to transition from Fast Braking to DC Brake. When DC Brake w/Auto ShutOff is selected,
this parameter sets the level sensitivity for shut off.
Default:
Min/Max:
1.00
0.01 / 5.00
RW Real
403 Brake Off Adj 2
Brake Off Adjustment 2
When Fast Braking is the selected Stop Mode, this parameter sets the frequency
sensitivity to transition from Fast Braking to DC Brake. When DC Brake w/Auto ShutOff is
selected, this parameter sets the time sensitivity for shut off.
Default:
Min/Max:
1.00
0.01 / 5.00
RW Real
409 Dec Inhibit Actn
Deceleration Inhibit Action
Configures the response to a Decel Inhibit condition, which occurs when the drive is not
decelerating. One possible cause could be bus voltage regulation.
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run.
Enable with P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
Default:
Options:
3 = “FltCoastStop”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor”
3 = “FltCoastStop”
