Hello All,
Fanuc S-430iW with RJ3 controller.
We're having SRVO-057 FSSB Disconnect fault on all 6 axis. I've replaced the fiber optic cables, the main control card on the amplifier. At this point I want to swap the main controller, but I can't get a full backup. It get's all 12 FROM backups, but fails to get the last image,which is SRAM.
We can cycle power and keep going without having to do anything else.
Now all of a sudden, we have 2 other robots faulting for the same thing. Really weird. It was discovered on one robot while someone was doing a PM on the E-stops and just checking to make sure they function correctly.
Let me know your thoughts. Thanks.
