SINAMICS G120 CU230P-2 Control Units
56 List Manual (LH9), 04/2014, A5E33838102B AA
Description: Displays the internal resistance of the power unit (IGBT and line resistance).
Description: Sets the configuration for the output voltage measurement of the power unit.
Note: Only special power units support this function (e.g. PM330).
Re bit 01:
The controller can be set using p0245 and p0246.
Description: Sets the shutdown thresholds for the ground fault monitoring.
The setting is made as a percentage of the maximum current of the power unit (r0209).
Index: [0] = Threshold at which pre-charging starts
[1] = Threshold at which pre-charging stops
Dependency: Refer to: p1901
Note: This parameter is only relevant for chassis power units.
Description: Displays the actual maximum output current of the power unit taking into account derating factors.
