I have a similar problem, I'm using a Sinamics S120 with CU320-2DP, a got this faults 1600 (9999), 1611 (2001), 30600 (9999) and 30611 (2001). I was reading a similar problem but one recommendation is "check the wiring of the safety-revelant inputs (SGE)" where are this contacts?? I'm looking for a manual please.

Hello,

this fault F30611(1951) is a known issue, the firmware of the CU320-2 must be upgraded to the version V4.4 HF11 (4.40.23.22)or HF12 (4.40.23.25), then this fault will disappear.
