Hi all, working on a 4NE-600 lathe with fanuc 6T control, the turret won't function properly, it seems like the rough index pin/slowdown solenoid stays on constantly regardless of the limit switch states. Does anyone have a wiring diagram for this machine?

Update on this /need help!

After spending more time on this machine I have discovered that when you first turn it on in the morning it will work fine for the first half hour or so. It shifts spindle gears, indexes the turret, everything works as it should. After its been running for a little while it seems like something hangs the plc up, and this is when the turret will no longer index, the spindle gears will no longer shift, and the coolant pump stays on no matter what. I've replaced bad cooling fans in the electrical cabinet and its not getting hot in there. Anybody have any ideas? Or a wiring /ladder diagram?
