I have several early 1990's Toyoda HMC's that have a MC-256 controller running a servo driven pallet changer. One is reacting strangely and I don't want to make a boatload more work for my ignorance. There is an LCD "pendent" snapped on each machine. Are the params stored in this pendent or are they deeper in the drive? The pendent is not responding, I can't tell if there is anything wrong with the drive. I am getting occasional overtravel errors after tearing the 4th out to repair a hydraulic leak. I think I need to adjust zeroing a few thousandths of a degree, but I can run until I know what I am doing. anybody have a manual/ knowledge of these things? How many cvariants are there?
