Description
Maximum current supplied during torque boost.
Value in percent of the nominal motor current.
Defines the minimum and maximum torque boost time.
If torque boost time is less than 40% of frequency
acceleration time (see parameters
torque boost time is set at 40% of frequency acceleration
time.
Nominal motor time.
Selects the method used to stop the drive. See also section.
Speed compensated stop
Speed compensated stop is active only if
• the operation mode is not torque, and
• parameter 21.03 Stop mode
• parameter 20.11 Run enable stop mode
case Run enable is missing).
Stop according parameter
compensated stop.
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.
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.
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.
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.
Speed delay.
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.
Speed threshold as a percent of the motor nominal speed.
