Emf Controller P Gain / Emf Ctr Kp; Emf Controller Integral Time / Emf Ctr Tn; Emf Controller Droop / Emf Ctr Droop; Emf Controller Pre-Control Setpoint Smoothing Time Constant - Siemens SINAMICS DCM List Manual

Value: 0:
1:
Dependency: Refer to: p50284
Note: If value = 0:
The integral component of the EMF controller is kept constantly at zero (i.e. the EMF controller functions solely as a
proportional controller).
p50275[0...n]

EMF controller P gain / EMF 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 EMF controller.
Dependency: Refer to: p50276
Note: The parameter is set automatically during the optimization run for field weakening (p50051 = 27).
p50276[0...n]

EMF controller integral time / EMF ctr Tn

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.010 [s]
Description: Sets the integral time of the EMF controller.
Dependency: Refer to: p50275
Note: The parameter is set automatically during the optimization run for field weakening (p50051 = 27).
p50277[0...n]

EMF controller droop / EMF ctr droop

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [%]
Description: Sets the value for the EMF controller's droop feedback.
Note: If value = 0:
Droop feedback is de-activated.
p50280[0...n] EMF controller pre-control setpoint smoothing time constant / EMF 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 EMF controller pre-control.
Dependency: Refer to: p50283
Note: This smoothing enables the EMF controller pre-control to be decoupled from the EMF controller.
