I had the X axis driver fail on an Intertech QuickTurn 42-9LSS CNC Lathe. It's a weird Taiwanese machine that's an orphan, and I knew when buying it that the day may come when not having support would bite me; it was cheap and has done very well, certainly paying for itself, but that day of failure is upon us.
The drive in question is a Mitsubishi MR-J2S-100A. I bought a "used & tested" replacement off ebay, and set all the parameters to match the old one. The alarm that had been on is now gone, but as soon as I try to jog X there's a "X Axis Loss Pulse" alarm and it's not moving. The servo is locked up (holding it's position, whatever the correct term is), so something is happening, just not everything that should be going on.
Any suggestions?
