When an external 24 V supply is connected to terminal X9, it must be
noted that the capacitors in the electronics power supply of the
connected Power Module must be charged when the external 24 V
supply is switched on. In other words, the 24 V supply must initially
supply a peak curren t which can amount to a multiple of the current
I
DC ext
calculated according to the table, in order to charge these
capacitors. Account must be taken of this peak current when protective
devices such as miniature circuit breakers are installed. The peak current
flows for a period t
e
lasting only a few 100 ms. The peak value is
determined by the impedance of the external 24 V supply or its
electronically limited maximum current.

external 24 V supply is switched on
4.5 Factory settings (defaults) of customer interface on SINAMICS G130
The following factory settings are provided to simplify configuring of the customer interface and commissioning. The
interfaces can also be assigned as required at any time.
1. The converter is controlled via the PROFIBUS interface (CU320-2 DP) or the PROFINET interface (CU320-2
PN) which are integrated as standard. The digital inputs and outputs on the Control Unit are used to incorporate
external alarm and/or error messages and control signals.
