I'd appreciate advice on this.
My customer's IRB 2400 M2004 threw this code a few days ago, on the extended axis. I checked connections, and today I replaced the SMB with the updated board and battery, not the same units that came out, but ABB assures me of their compatibility. I also replaced the network node on the SMB, and the cable to the controller. I fired it up, calibrated, updated the counter, and it threw the same error. So, I think I should have replaced the resolver too, but I want to test it first. I could swap it with a robot axis, and I could check the voltages if I had the pinout. Does anyone have any other suggestions?
Thank you
