Hi all
I am working on a Fanuc R2000ib/150u robot, R30iA controller.
This robot has been working flawlessly for a while now, and recently I picked up the teach pendant and noticed it was frozen, so I manually cycled the power. Since then I have not been able to get it to boot up. I noticed when I turn on the power that the external fan on the door doesn't come on and there is indeed no voltage there, everything else seems to power up. Attached are pictures showing the teach pendant state where it gets stuck, and the CPU state. I can get into the maintenance mode on the pendant, I did a ram test, all seems good, and I took an image backup just in case. I have checked a bunch of random fuses and have not found any issue yet.
So does anyone have any idea what else I might check?
thanks in advance.
