We are facing an issue of frequent alarm 1345 in one of our paint robot With NX100 controller.
This is a single robot without external axis.
Alarm is coming 1345 Safe circuit signal not same (SV) with subcode 104.
We have interchanged NTU unit, Axa board, CPS power supply unit with similar robot also have tightened all connectors on NTU unit and Hot line connector from both ends.
Still problem has not been resolved or shifted to other robot with which we have interchanged these items.
Please suggest solution to fix this problem.
