Hello All,

I have a machine that's using a D435 fw4.1 and SINAMICS Integrated fw2.5. I am receiving an issue where the infeed bus is unable to unable to start. I'd like some info on what I should check next.

Incoming voltage on each phase has already been checked. This system was working previous to a download that modified some logic as well as one the name of an axis/drive; no other parameters were changed, which is why it's strange to me that I am suddenly getting a voltage dip especially when no motor are commanded to run when I attempt to get the infeed module started.

I also noticed the infeed is missing OFF1, OFF2, Enable Operation, and OFF2 enable internal. p922 is configured to 370 (default PZD telegram) but due to my unfamiliarity with the D435 I don't know what object is transmitting that telegram (the CU, right?)

If this device is connected to a PLC via Profibus or Profinet and the device name was changed, the communications would have stopped right then.

The PLC project's Profinet name and IP address must match exactly what is configured in the drive.

Why would someone change the name on one device and not the other?
