Error 9, Absolute Position Malfunction and spontaneous rebooting.

[AeroDefense]

Hello All,
I have a Nexus 510C-II with Error 9, Absolute Position Malfunction. The only operator who knew it had to move and, aside from a couple pages of notes, everything was in his head. For the record I'm not a supporter of tribal knowledge, he was here before my time, lol.

I think the machine was powered down with a dead backup battery. Is resetting the absolute position user settable or do we need to call a mazak tech to do it?

Also, the control spontaneously reboots and I have zero idea what's causing it. Perhaps related to the Abs pos malfunction?

Any suggestions are greatly appreciated!

Check the batteries on the absolute encoders, bet they are low or dead
