Hi

I have problem with one of our sinamics 120 drives. Namely F31118 appears often.

We replaced encoder, encoder cable, changed cable path as well as ground the cable shield at both ends but no result.

We checked all connectors on SMC30, replaced drivecliq cable and checked power supply. Problem still appears.

Can the problem be in SMC30 module?

Does anyone has experience with faulty SMCs?

I attached the image from the trace when fault triggered

 Dear Yurius, 

We are also facing a similar issue. Could you find a solution ? A quick reply would be highly appreciated.
