Having some issues with a 401 error and not sure how to solve this. Any help would be appreciated
OK so I've double checked the JX1B -> JX1A cable and I actually made a new cable 1 to 1 to guarantee that it worked following this pinout:
I put a jumper on JX1B of the SVM using this pinout
I know my IO link cable works as it is working on a servo amp that has a built in power supply. I know the parameters are good on the NC as I can run this servo amp and I get 0 on the screen.
I have now set everything up as per our conversation but still no luck. No faults apart from 401 and the PSM never tries to come out of "--" and the contactor never fires.
I have tried 3 SVMs and 2 PSMs all which were repairs but only had bad fans and capacitors. There's a chance that they dont all work but seems slim to me.
I have in the past made a jumper for JX1B which grounds IALM and MCCOFF, with this jumper in place I can get the contactor to fire and the PSM to go to 00. with the regular jumper of 5 and 6 jumpered nothing happens.
Here's my current setup:
Is there a chance that the NC needs to be parameterised differently? I say this as my second head servo amplifier never enables even though it is plugged in correctly, maybe its expecting to see more units?
I'm stuck - any further help would be most appreciated.
thanks!
