I am having random e-stop detected mid program. Sometimes it will happen every few second over and over. Sometimes it will say a limit switch, but that is less frequent.
I started by replacing the wiring with shielded wire. Before anyone asks, yes the shielding is properly grounded. I also replaced the breakout board twice. Watching the diagnostic page I never see the e-stop or limit switch light up even as the program stops running. The only piece in the chain I haven’t replaced is the UC100 itself. I am starting to suspect that is defective.
Has anyone else had this issue? Any suggestions on troubleshooting to confirm whether this UC100 is bad?
