D445 Alarm Error 20005 reason: 0x4h

Nghiemnv

Can you explain in more delail? please...

 Exactly like Chris said :

In Siemens if you have a 20005, the guilty is NOT the Simotion.

The guilty is the "sinamics".

This means that your physical motor/drive has a problem. So you must go online with Sinamics Integrated (or the related CUs) and check THERE the real nature of the problem.

Basically speaking : 20005 means "nothing" if you want to troubleshoot. It does not help.

This is one of the earliest traumas that a young Simotion programmer has, since he thinks that 20005 means something of specific. But it's wrong.

this faults are the reason for the alarms

 Could you explain how to determine that these three alarm messages are related to the 20005 he mentioned?

I encountered the same 20005 ALARM, CU320 was online and there was no other alarm in the alarm TAB.

Attached is the diagnostic buffer file.
