Hope anyone can help me out. We got a DMU50V in an auction and finally got it powered up the other day and I get a few errors. E01 whch is interface missing and i can clear it then when I hit the on button I get E15. Which in the book says input spindle/feed halt is low. Any ideas? the only thing the machine will do is engage the draw bar. I cannot get any of the Axis to energize and move and the spindle will not turn. I got all the manual except electrical and service.
