160 Parameters
21.30 Speed compensated
stop mode
Selects the method used to stop the drive. See also
section Speed compensated stop on page 75.
Speed compensated stop is active only if
• the operation mode is not torque, and
• parameter 21.03 Stop mode is Ramp, or
• parameter 20.11 Run enable stop mode is Ramp (in
case Run enable is missing).
Off
Off Stop according parameter 21.03 Stop mode, no speed
compensated stop.
0
Speed comp FWD If the direction of rotation is forward, 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 reverse, the drive is stopped
along a ramp.
1
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%
22
22 Speed reference
selection
Speed reference selection; motor potentiometer settings.
See the control chain diagrams on pages 448…452.
22.01 Speed ref unlimited Displays the output of the speed reference selection
block. See the control chain diagram on page 448.
This parameter is read-only.

-30000.00… 30000.00
