PLC: CPU 1515TF-2 PN Motor CU: Sinamics s120 CU320-2 PN Motors are configured in Sinamics Starter, configuration is ok. TechObject: TO_SpeedAxis In the same CU are 3 SpeedAxes problem ist just with one of them, with separated PowerModule: 6SL3120-1TE28-5AAx. Whats going on? After a few days of normal working I switched off Infeed. After that, I get a problem wit MC_Power block. When i start it, Infeed and PowerUnit are switched off after a ~5s (they are completly dead till supply restart). I started to test whole configuration, and the drive is running normally in commisioning mode and controled by Sinamics Starter. So I use a different call of MC_Power - it makes nothing, Builded new TO - it is giving the same result. Can someone help me? Have someone such a problem?

By switching on an on you may reset the fault, so it runs again. You can reset the fault of the infeed, either oder Profinet or with a wired signal, depending on the type of your infeed.
