Hello everyone,
On our Fanuc robot 120ibe with RJ3 controller we suddenly started getting a SRVO-248 Deadman switch status abnormal.
Whenever we press the deadman switch halfway the error shows up. When we release the switch the SRVO-236 Chain failure is repaired appears. We press RESET and try again but the same error sequence occurs. We reset the alarm "RES_1CH" but still no luck.
We have checked so far:
1. cable between pendant and controller (all pins from pendant are properly connecting to controller
2. fuses on estop panel (fuse1 , Fuse2)
3. pendant switches (checked by dismantling pendant and check the switch operation)
Any advice would be greatly appreciated.
Thanks
