Field-Generating Current Setpoint Smoothing Time Constant; Field-Generating Current Setpoint (Steady-State) / Id_Set Stationary; Field-Generating Current Setpoint Total / Id_Setp Total; Excitation Current Setpoint Calibration / I_Exc_Setp Cal - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
If the value that is entered exceeds the rated speed, then a change is made to the inner cos phi = 1 over the complete
speed range.
p1622[0...n] Field-generating current setpoint smoothing time constant / Id_setp T_smth
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
0.1 [ms]
Description: Sets the smoothing time constant for the setpoint of the field-generating current components.
The current filtered in this way is included in the calculation of the cos phi.
r1623[0...1]

Field-generating current setpoint (steady-state) / Id_set stationary

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Displays, signals
Not for motor type: PEM, REL
Min
- [Arms]
Description: Displays the steady-state field generating current setpoint (Id_set).
Note: Re index 1:
Displays the stationary field-generating current on the stator side in the case of separately excited synchronous
motors without the excitation current monitoring component (r1644).
r1624

Field-generating current setpoint total / Id_setp total

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Displays, signals
Not for motor type: REL
Min
- [Arms]
Description: Displays the limited field-generating current setpoint (Id_set).
This value comprises the steady-state field-generating current setpoint r1623 and a dynamic component that is only
set when changes are made to the flux setpoint.
p1625[0...n]

Excitation current setpoint calibration / I_exc_setp cal

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: ASM, PEM, REL
Min
10.0 [%]
Description: Sets the gain factor to weight the excitation current setpoint.
