Hello - I have a Fanuc RJ3 controller that I haven't been able to get fully operational... I've discovered that the cable and connectors from CRP12 to CRP10 is missing! I've tried to understand the pinouts of these, but not 100% clear what is what. Can anyone help me with pinouts at these locations? Or supply the cable for connecting these two? I don't mind making a cable, but need to know the pinouts and what goes where. CRP12 on the servo amp seems to have 12 pins, while the CRP10 on the motherboard seems to have 20 pins; So perhaps some pins are not used, or some originate from another location?
Thanks for your help!
