Torque limiting changeover speed / T lim n_chng

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.00 [%]
Description: Sets the changeover speed for torque limit selection.
Dependency: Refer to: r52166
Note: If torque limit changeover is selected (p50694 = 1) and the speed (p52166) is higher than the changeover speed set
in p50184, then torque limit 2 (p50182, p50183) is activated in place of torque limit 1 (p50180, p50181).
p50190[0...n] Cl-loop arm current ctr prectr setpoint smoothing time constant / Ia prec set T
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [ms]
Description: Sets the time constant for smoothing the armature current setpoints at the armature current pre-control input for
closed-loop armature current control.
Note: The smoothing time constant is used to decouple armature current pre-control from the armature current controller.

Description: Sets the time constant for smoothing the armature setpoint for closed-loop armature current control.
Note: The smoothing time constant is used to decouple armature current pre-control from the armature current controller.
