Description: The saturation characteristics (flux as a function of the magnetizing current) is defined using 4 points.
This parameter specifies the x coordinate (magnetizing current) for the 3rd value pair of the characteristic.
Sets the third magnetization current of the saturation characteristic in [%] with reference to the rated magnetization
current (r0331).
Dependency: The following applies for the magnetizing currents:
p0366 < p0367 < p0368 < p0369
Refer to: p0364
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 characteristics (flux as a function of the magnetizing current) is defined using 4 points.
This parameter specifies the x coordinate (magnetizing current) for the 4th value pair of the characteristic.
Sets the fourth magnetization current of the saturation characteristic in [%] with reference to the rated magnetization
current (r0331).
Dependency: The following applies for the magnetizing currents:
p0366 < p0367 < p0368 < p0369
Refer to: p0365
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
Description: Displays the motor stator resistance at an ambient temperature (p0625).
The value does not include the cable resistance.
Dependency: Refer to: p0625
Description: Displays the total cable resistance between power unit and motor, as well as the internal converter resistance.
Dependency: Refer to: r0238, p0352
