Position overrun sounds like one of the travel limit switches is too
sensitive
to electrical noise, or possibly even vibration. You might check if any
cable shielding has gone bad, and that necessary pullup resistors are
set up properly on the inputs for the limit switches.

I don't know what the alarm 460 is, it just may mean you need to rehome
after what it thinks is a crash.
