Motor Saturation Characteristic I_Mag 2 / Mot Sat. I_Mag 2; Motor Saturation Characteristic I_Mag 3 / Mot Sat. I_Mag 3 - Siemens SINAMICS G150 Manual

Dependency: The following applies for the magnetizing currents:
p0366 < p0367 < p0368 < p0369
The following applies for the stator quadrature axis current values (PESM):
20 % < p0366 < p0367 < p0368 < p0369
Refer to: p0362
Notice: For permanent-magnet synchronous motors (PESM), the following applies:
If the parameters are not set as specified, i.e. not in ascending order and to more than 20 %, the unsaturated
quadrature inductance (p0356) is always used for quadrature axis flux calculation purposes.
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).

Motor saturation characteristic I_mag 2 / Mot sat. I_mag 2

VECTOR_G Can be changed: C2(3), U, T

5.0 [%]
Description: The saturation characteristic (flux as mapping of current) is defined using 4 points.
This parameter specifies the x coordinate for the 2nd value pair of the characteristic.
Induction motors (ASM) and separately-excited synchronous motors (SESM):
The saturation characteristic describes the mapping of the magnetizing current onto the motor flux.
The parameter sets the second magnetizing current as a [%] referred to the rated magnetizing current r0331 (ASM),
which in turn is referred to the no-load excitation current (SESM).
Permanent-magnet synchronous motors (PESM):
The saturation characteristic describes the mapping of the stator quadrature axis current onto the stator quadrature
axis flux.
The parameter sets the second stator quadrature axis current as a [%] referred to the rated motor current (p0305).
