2.2 List of parameters
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).
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.
Description: Sets the control word for the Alpha W limit on the armature.
Value: 0: Alpha W limit = 165 ° with pulsating armature current
1: Alpha W limit = p50151
Note: If value = 0:
Continuous current: Alpha W limit = parameter p50151
Pulsating current: Alpha W limit = 165 °
If value = 1:
Alpha W limit = parameter p50151
