Re: SCM TECH 95
First let me say that I have never worked on one of these, I did see one working once. But may be able to offer some general troubleshooting ideas, having been working on machines for many years. If possible have a chat with the operator to ask about what happened to the machine just prior to the problems occurring.
First I would manually back the axes off of the limits, and restart the the system. If that clears some of the errors then life is better.
If on power up the axes limit out again, then I might check the power supplies for proper voltage.
Power down, remove and reinstall any plugs, connectors, and computer cards. Maybe some cleaning would be in order. Retighten wiring terminals, especially any terminal to terminal jumpers. Power up and try again.
If all that fails, then I see two options: 1) Boat anchor, or 2) a controls upgrade if the machine is mechanically OK. I have a very low tolerance for antique controls.
