Homing process not completed

Hi. I have a 8msa4l.e3-31 motor connected to an acopos 1045 drive. Recently the machie does not complete the homing process and I get error codes regarding the encoder (5034, 7039, 7040, 7041). Because the machine has two same acopos drivers, I used the encoder cable of the motor that worked to check the functionality of the cable but the problem insists. I also exchanged the ac120 card with the working one, but the problem insists again. Finally, I dismantled the motor, a servo motor specialist checked it and found no problem of the motor and the encoder. I put the motor on the machine again, set the abs encoder but I have again the same problem. Do you have any thoughts?

Hi @Soumis ,

welcome to our community !

the error messages seem to me to be unambiguous …?
There is a problem with the encoder signals.

So if you have a second axis of the same type, you can swap everything to determine whether the electronics, cables or motor are faulty.

Is it a B&R cable or was it manufactured externally?

Secondly there are some Parameters you can trace to check the analogue signals:
