Hi All

I have a Fanuc wire edm with a 16-wa controller that has come up with a 920 alarm as per the picture attached. From what I can see in the manual it’s an issue with of the axis control cards (it has) but can anyone guide me as to which one I should change or is it just swap each one until the fault doesn’t happen again. Also can I remove the fs16/18 board without losing parameters? I don’t have a sram backup as it always comes up with a parity error when I try to do it. This has been an issue for years but the machine has worked fine. Appreciate any advice.

Thanks
