Fanuc CPU problems

Fanuc CPU problems

Fanuc CPU problems

(OP)
I have a problem with a RJ2 robot controller. The teach pendant is continually freezing however is ok if the robot power is cycled. The only fault indication i have is via the LED indication on the CPU. This points to bad parity on the RAM. I am reluctant to change the CPU though due to not having a very recent back-up. Can anyone offer any advice

RE: Fanuc CPU problems

I had the same problem with a RJ3 controller.  I finally had to send the CPU out to be repaired.
