SINAMICS G120 CU230P-2 Control Units
58 List Manual, 04/2018, A5E33838102
Description: Displays the power unit fan operating hours.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: p0252
Refer to: A30042
Note: For liquid-cooled chassis power units, the operating hours of the inner fan are displayed in p0251 and not in p0254.
Description: Sets the maximum operating time of the power unit fan.
The prealarm (warning) is output 500 hours before this set value.
The monitoring is deactivated with p0252 = 0.
Dependency: Refer to: p0251
Refer to: A30042
Note: For PM330 power units, the maximum operating time of the fan on the power unit is saved and displayed in p0252.
The "Restore factory setting" function or a project download does not influence p0252. Users can manually change
the maximum operating time of the fan. The modified value is also saved to the power unit.
Description: Displays the power unit fan operating hours of the internal fan in the power unit.
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has been replaced).
Dependency: Refer to: A30042
Note: For liquid-cooled chassis power units, the operating hours of the inner fan are displayed in p0251 and not in p0254.
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 precharging starts
[1] = Threshold at which precharging stops
Dependency: Refer to: p1901
Refer to: F30021
Note: This parameter is only relevant for chassis power units.
