Rev. Counter Not Updated Axis 4,5,6

Robot Controller
1

Hi all,
I’m having issues with an Irb 2600.
The SMB was replaced with a new one because the previous one stopped working and, every now and then the my IRB gives me a REV Counter Error involving Axis 4,5,6.
They get unsynchronized 2-3 times a week.

The SMB has been replaced.
The Cable has been Checked for loose connections.
The feedback connection have been checked and so far nothing.

Ideas?
Thank you

Did you also check the SMB cable for pins maybe pushed in on both ends? How about the SMB battery? Has it been replaced if necessary?

We have changed the SMB once again and have not had any issues. Maybe the second SMB was faulty as well?
Thanks for your response.
