Description: Sets the delay time for automatic field current reduction.
Description: Sets the smoothing time constant for the setpoint for field current pre-control.
Dependency: Refer to: p50261
Note: This smoothing enables field-current pre-control to be decoupled from the field current controller.
Description: Sets the smoothing time constant for the setpoint for the field current controller.
Dependency: Refer to: p50260
Note: This smoothing enables field-current pre-control to be decoupled from the field current controller.
Description: Selection of the input variable for determining the motor flux.
Value: 0: Field current controller actual value (r52265)
1: EMF pre-control output (r52293 or r52268)
2: Field current controller setpoint (r52268)
Note: If value = 0:
This setting is recommended for a fully compensated DC motor.
If value = 1:
This setting is recommended for an uncompensated DC motor. The EMF controller must be active for this setting (the
EMF controller compensates the armature reaction).
If value = 2:
This setting is recommended for a fully compensated DC motor.
