p0369[0...n] Motor saturation characteristic I_mag 4 / Mot sat. I_mag 4
Access level: 4 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 6723, 6838
Min:
5.0 [%]
Max:
800.0 [%]
Factory setting:
210.0 [%]
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
See also: p0365
Note
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
