Hello
I am currently working with the FANUC R-30ib Controller.
I'm using the I/O on CRMA15/CRMA16 --- CRMA58/CRMA59. I use external 24v to DOSRC1.
Everything worked fine, but one day when moving equipment the signals stopped working. After diagnostics it turned out that there was a short circuit between DOSRC1 and 0V on the robot side (!). The robot can move, there are no active errors. All fuses are fine.
What could be the problem?
