Deckel Maho 300c x04,y04

Hi! At the end of last year did i buy a maho 300c phillips 432. The battery was gone so i installed a new one and did type in the Parameters.

The pue light is on but the phases is checked and correct.

I can start the hydraulic but when I try to move the machine do i get x04, y04, z04 ( parity problem )

Could the machine lost something more than just the Parameters with the dead battery? Or what is the problem?

The machine seems to be in good condition , only 7000h

I'm grateful for all help i can get!

Regards Tobias
