Fanuc R-J with motn-18 position not reachable.

  • Hello everyone, I have an old R-J controller with a 100 s6 arm. We rebuilt a teach pendant and tried it out on it. It is now giving a "MOTN-018 Position not Reachable" error whenever you try to move it in world, tool, etc. It does not give an error when you use joint or run a program. The old pendant was put back on and it is still giving the same error. Any help would be greatly appreciated.
