hello everybody!

I need some help wit this old machine.
maybe this is not a machine problem, maybe it is a control problem.

i got this error:

DATENBITS FEHLEN! LADEN UEBER R26/R27;

however i have thesse parameters loaded:

N126 R26 + 8001022.
N127 R27 + 200.

what could be the problem? wrong data and this is all?

regards
Arnoild
