Parameters 177
Speed comp REV
If the direction of rotation is reverse, speed compensation
is used for constant distance braking. Speed difference
(between used speed and maximum speed) is
compensated by running the drive with current speed
before the motor is stopped along a ramp.
If the direction of rotation is forward, the drive is stopped
along a ramp.
2
Speed comp bipolar
Regardless of the direction of rotation, speed
compensation is used for constant distance braking.
Speed difference (between used speed and maximum
speed) is compensated by running the drive with current
speed before the motor is stopped along a ramp.
3
21.31
Speed compensated
stop delay
This delay adds distance to the total distance traveled
during a stop from maximum speed. It is used to adjust
the distance to match requirements so that the distance
traveled is not solely determined by the deceleration rate.
0.00 s
0.00…1000.00 s
Speed delay.
1 = 1 s
21.32
Speed comp stop
threshold
This parameter sets a speed threshold below which the
Speed compensated stop feature is disabled. In this
speed region, the speed compensated stop is not
attempted and the drive stops as it would, using the ramp
option.
10%
0…100%
Speed threshold as a percent of the motor nominal speed. 1 = 1%
21.34
Force auto restart
Forces automatic restart. The parameter is applicable only
if parameter

.
Disable
Disable
Force auto restart disabled. Parameter
21.18
Auto restart
time
is in effect if its value is more than 0.0 s.
0
Enable
Force auto restart enabled. Parameter
21.18
Auto restart
time
is ignored. The drive never trips on the undervoltage
fault and the start signal is on forever. When he DC
voltage is restored, the normal operation continues.
