2.2 List of parameters
Description: Sets activation/de-activation of the integral component on the field current controller.
Value: 0: Deactivated
1: Activated
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).
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).
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).
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).
