Hi @PEMA ,
Welcome to the community!
We need SystemDump to get more information, if you are not familiar with that please read this post How to collect a System Dump from a B&R controller .
Regarding status indicators on the drive (ACOPOS User’s ver 2.10 page 31 ):
You can download ACOPOS User’s manual from our website.
You are very welcome to the community, but normally when you have an issue on your machine you should call your machine builder, Kosme in your case.
I worked with them in the past, they have a service team with deep B&R knowledge (HW and SW).
Thanks
Ciao
