p50254[0...n] Field current controller integral component activation / I_field_ctr I comp
DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Sets activation/de-activation of the integral component on the field current controller.
Value: 0:
1:
Dependency: Refer to: p50255, p50256
Note: If value = 0:
The integral component of the field current controller is kept constantly at zero (i.e. the field current controller
functions solely as a proportional controller).
p50255[0...n]

Field current controller P gain / I_field ctr Kp

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.01
Description: Sets the P gain of the field current controller.
Dependency: Refer to: p50256
Note: The parameter is set automatically during the optimization run for closed-loop field current control (p50051 = 24).
p50256[0...n]

Field current controller integral time / I_field ctr Tn

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.001 [s]
Description: Sets the integral time of the field current controller.
Dependency: Refer to: p50255
Note: The parameter is set automatically during the optimization run for closed-loop field current control (p50051 = 24).
p50257[0...n]

Closed-loop field current control standstill field / If_ctr stst_field

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [%]
Description: Sets the standstill field for closed-loop field current control.
Dependency: Refer to: p50692
Note: The field current is reduced to this value when the "Automatic field current reduction" function is parameterized
(p50082 = 2) or in the case of signal-driven selection of the ""Standstill excitation" function (p50692).
