216 Parameters
21.26 Torque boost
current Maximum current supplied during torque boost. 100.0
15.0…300.0% Value in percent of the nominal motor current. 1 = 1
21.27 Torque boost time Defines the minimum and maximum torque boost time.
If torque boost time is less than 40% of frequency
acceleration time (see parameters
28.72 and 28.74 ), then
torque boost time is set at 40% of frequency acceleration
time.
20.0 s
0.0...60.0 s Nominal motor time. 1 = 1%
21.30 Speed
compensated stop
mode Selects the method used to stop the drive. See also section.
Speed compensated stop (page 76 ).
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.

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.

21.31 Speed comp 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
0.00…1000.00 s Speed delay. 1 = 1
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
95.04 Supply voltage is set to External 24V .
Disable
Disable Force auto restart disabled. Parameter 21.18 Auto restart
time is in effect if its value is more than 0.0 s.
