Hi Can someone help please?

We have a Europa 2000 VS milling machine.

The PLC program got corrupted and the machine would not boot up, just came up with the error of the PLC program was corrupt.

We found some backup files on the control and after copying these over we managed to get the machine working again.

The problem we now have is that the X and Y axis are moving in the opposite direction + is moving - and vice versa but the reference sequence is correct?

I'm assuming it must be a parameter that has changed when we have used the backup files.

Prior to the PLC program becoming corrupt it was working fine.

any help would be much appreciated

Regards Andy
