SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011

Description: Sets the absolute value by which the threshold to initiate the undervoltage fault (F30003) is reduced.

Dependency: Refer to: p0210, r0296

Refer to: F30003

Notice: When using a Control Supply Module (CSM) for 24 V supply from the DC link, the minimum continuous DC link volt-

age may not lie below 430 V. DC link voltages in the range 300 ... 430 V are permissible up to a duration of 1 min.

For chassis power units, this parameter has no significance.

Note: The resulting shutdown threshold can be read in r0296 and is dependent on the selected rated voltage (p0210) and

the power unit being used.

Description: Sets the shutdown thresholds for the ground fault monitoring.

The setting is made as a percentage of the maximum power unit current (r0209).

Index: [0] = Threshold at which pre-charging starts

[1] = Threshold at which pre-charging stops

Dependency: Refer to: F30021

Description: Displays the actual maximum output current of the power unit taking into account derating factors.
