Closed-Loop Armature Current Control P Gain / Ia Ctr Kp; Closed-Loop Armature Current Control Integral Time / Ia Ctr Tn; Current Limitation Setpoint Integrator Selection / I_Set Integ Sel - Siemens SINAMICS DCM List Manual

Note: If value = 0:
The integral component of the armature current controller is kept constantly at zero (i.e. the armature current
controller functions solely as a proportional controller).

Closed-loop armature current control P gain / Ia 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 armature current controller.
Dependency: Refer to: p50175
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).
The P gain (Kp) for the armature current controller is calculated as follows:
Kp = p50155 x |p50175|

Closed-loop armature current control integral time / Ia ctr Tn

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32

0.001 [s]
Description: Sets the integral time of the armature current controller.
Dependency: Refer to: p50176
Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the
armature converter (p50051 = 25).
The integral time (Tn) for the armature current controller is calculated as follows:
Tn = p50156 x |p50176|

Description: Selection of the current setpoint integrator.
Value: 0:
1:
Note: If value = 0:
The integrator is only effective after a change in torque direction (only functions as a ramp-function generator for the
current setpoint until the first time the output reaches the setpoint at the integrator input after a change in torque
direction).
If value = 1:
The integrator is always effective (functions as a ramp-function generator for the current setpoint).
