2 Parameters
2.2 List of parameters
p50258[0...n] Cl-loop field current control field current reduction delay time / If_ctr I_red t_del
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [s]
Description: Sets the delay time for automatic field current reduction.
p50260[0...n] Field current pre-control setpoint smoothing time constant / Field_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 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.
p50261[0...n] Field current controller setpoint smoothing time constant / I_field_ctr set T
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [ms]
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.
p50263[0...n]

Selection of motor flux input variable / Mot fl input sel

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Selection of the input variable for determining the motor flux.
Value: 0:
1:
2:
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.
