I was just getting my current machine back up and running after being away and I though I would just run it through a air cut to make sure all was ok. I have something very big to cut so was pushing it to it limits and all of a sudden the power went out and the the machine stopped. On restarting I the vfd showed a (DL) error and the spindle did not start. I cant find anything in the manual and not to much on the net but believe it maybe a short.. I have a feeling the earth wire or something as it appears it may have rubbed on the bracket that holds the wire and stops it moving however not 100% sure. not being a electrical type person im not to sure how to go about testing for what's wrong?
