Saturation Characteristic Speed To Determine / Sat_Char N Determ; Saturation Characteristic Magnetizing Current / Sat_Char I_Mag; Saturation Characteristic Magnetizing Inductance / Sat_Char L_Main - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
Note: When the rotating measurement is activated, it is not possible to save the parameters (p0971, p0977).
Parameter changes are automatically made for the rotating measurement (e.g. p1120); this is the reason that up to
the end of the measurement, and if no faults are present, no manual changes should be made.
The ramp-up and ramp-down times (p1120, p1121) are limited, for the rotating measurement, to 900 s.
For speed controller optimization with encoder (p1960 = 2, 4), the speed controller for encoderless operation is also
pre-assigned (p1470, p1472).
Depending on whether the speed controller optimization is carried out with or without encoder, different Kp/Tn
adaptations of the speed controller are set (p1464, p1465). If the drive should be controlled with as well as without
speed encoder, then we recommend the use of two drive data sets (p0180). These can then be executed with
different speed controller adaptations.
p1961

Saturation characteristic speed to determine / Sat_char n determ

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: REL
Min
26 [%]
Description: Sets the speed to determine the saturation characteristic and the encoder test.
The percentage value is referred to p0310 (rated motor frequency).
Dependency: Refer to: p0310, p1959
Note: The saturation characteristics should be determined at an operating point with the lowest possible load.
