My lathe was just hooked up to power and comes up with a ram parity error, as well, the board in the back has an E on it in LED lighting. Fanuc suggested that have a rep fly out, but that is a $2-3k expense due to my geographic location. Any economic solutions would be greatly appreciated.:drowning:

It been a long time since I worked on the system 10, but I think you have lost the battery and corrupted the memory.

You need to replace the NC batteries then clear the memory, then you will need to reload the parameters, programs etc;

you have procedures for this in the yellow Fanuc 10 maintenance manual.

If this doesn't work, maybe then the board is defective.
