2.2 List of parameters
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
Description: The saturation characteristic (flux as mapping of current) is defined using 4 points.
This parameter specifies the x coordinate for the 3rd 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 third 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 (PMSM):
The saturation characteristic describes the mapping of the stator quadrature axis current onto the stator quadrature
axis flux.
The parameter sets the third stator quadrature axis current as a [%] referred to the rated motor current (p0305).
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: p0364
Notice: For permanent magnet synchronous motors (PMSM), 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).
Description: The saturation characteristic (flux as mapping of current) is defined using 4 points.
This parameter specifies the x coordinate for the 4th 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 fourth magnetizing current as a [%] referred to the rated magnetizing current r0331 (ASM),
which in turn is referred to the no-load excitation current (SESM).
