1998 Kitamura Mycenter1 with Fanuc O-M control

I recently got this machine into commission after it sat for a year (stuck ATC and RS-232 communication issues) after moving it into my shop.

Today I had it running for a few hours. It stalled suddenly in the middle of a program. The display showed 945 serial spindle alarm 1CH. I shut the machine down completely and restarted it. Now it displays five servo alarms on startup.
400 servo alarm (over load)
408 servo alarm (serial not ready)
414 servo alarm (x axis detect err.)
424 servo alarm (y axis detect err.)
434 servo alarm (z axis detect err.)

This looks pretty bad to me. I have been doing some research on each individual alarm, but I'm thinking that all five plus the original 945 alarm indicate a major failure.
