Description
Defines the reference used in speed controller output
balancing. The output of the speed controller is forced to this
value when balancing is enabled by parameter
ctrl balance enable.
In order to guarantee smooth operation during output
balancing, the D-part of the speed controller is disabled and
the acceleration compensation term is set to zero.
Speed control output balancing reference.
Defines the minimum speed controller output torque.
Minimum speed controller output torque.
Defines the maximum speed controller output torque.
Maximum speed controller output torque.
Defines the proportional gain for the speed controller when an
emergency stop is active. See parameter
gain.
Proportional gain upon an emergency stop.
Displays the output of the proportional (P) part of the speed
controller. See the control chain diagram on page 293.
This parameter is read-only.
P-part output of speed controller.
Displays the output of the integral (I) part of the speed
controller. See the control chain diagram on page 293.
This parameter is read-only.
I-part output of speed controller.
Displays the output of the derivative (D) part of the speed
controller. See the control chain diagram on page 293.
This parameter is read-only.
D-part output of speed controller.
Displays the output of the acceleration compensation
function. See the control chain diagram on page 293.
This parameter is read-only.
Output of acceleration compensation function.
Displays the acceleration-compensated output of the speed
controller. See the control chain diagram on page 293.
This parameter is read-only.
Acceleration-compensated output of speed controller.

Displays the torque reference given to the torque controller in
percent. See the control chain diagram on page 296.
This parameter is read-only.
