Thanks panic mode. Its always nice to hear your prespective. I did contact kuka but they have yet to respond.
As for self diagnosis, i did a full top to bottom check inside the KRC but there is nothing wrong inside. Following the Eplan, all cables are good, no error lights, and fuses are good.
I have also removed X11 and the smart pad to make sure they are not the causes...but still the same issue comes up.
Does this mean it is from outside the KRC and if so can it be a faulty RDC?
I dont want to mess around with the RDC since i have not read anything about it....
Regards
