SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013

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 magnetiza-

tion 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

Description: Displays the rated motor stator resistance at rated temperature (total of p0625 and p0627).

Dependency: Refer to: p0627

Note: The parameter is not used for synchronous motors (p0300 = 2xx).
