Field Characteristic Status / Field Char Stat; Emf Rated Value / Emf Rated; Rated Speed / N_Rated - Siemens SINAMICS DCM List Manual

Note: The parameter is set automatically during the optimization run for pre-control and the current controller for the field
converter (p50051 = 24).

Field characteristic status / Field char stat

DC_CTRL Can be changed: T
Data type: Integer16
P-Group: -
Not for motor type: -
Min
0
Description: Status of the field characteristic.
Value: 0:
1:
Note: The parameter is set automatically during the optimization run for field weakening (p50051 = 27).
If p50117 = 1, the field characteristic is valid (p50118 to p50139).
p50118[0...n]

EMF rated value / EMF rated

DC_CTRL Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0 [%]
Description: Sets the EMF generated at full field (corresponding to p50102) and a speed according to p50119.
Dependency: Refer to: p50119
Note: This parameter is set automatically during the optimization run for field weakening (p50051 = 27).
Only the ratio of p50118 to p50119 is decisive for field weakening control.
If p50102 is modified subsequently or the maximum speed is altered downstream, the optimization run for field
weakening has to be repeated.
If p50100, p50101 or p50110 is modified subsequently, the optimization run for field weakening does not have to be
repeated.
p50119[0...n]

Rated speed / n_rated

DC_CTRL Can be changed: T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [%]
Description: Sets the speed generated at full field (corresponding to p50102) and an EMF actual value according to p50118.
Dependency: Refer to: p50118
Note: This parameter is set automatically during the optimization run for field weakening (p50051 = 27).
Only the ratio of p50118 to p50119 is decisive for field weakening control.
If p50102 is modified subsequently or the maximum speed is altered downstream, the optimization run for field
weakening has to be repeated.
If p50100, p50101 or p50110 is modified subsequently, the optimization run for field weakening does not have to be
repeated.
