Hi all,

on a plant we have installed a Sinamics G120P that works fine but, from Yesterday it displays on the front panel the fault 0A300 16. It seems works without any problem but only the communication seems broken: we cannot find any info on the manuals regarding this fault.

We try to solve the problem with a standard power off and restart  and with the fault acknowledgment from the front panel but without a solution.

Do you have any info/idea to solve it?

Many thanks in advance
