I have this arm and control that I bought from eBay. I rewired it to run from 220v single phase and for the most part, everything powers up including the pendant with flashing lights. I am completely new to robotics and am teaching myself and learning for fun. Anyway, all the joint drives power up with a green light except for joint 4 servo driver. It has a red fault light on the front. The Baldor BPS 10 PSU is also not showing signs of life with no lights lit up on front of it. I'm assuming it's damaged or dead. The pendant says Lost Communication with controller also. Curious on what my next steps should be. I tried attaching pics but I can't figure that out. I'm guessing I don't have the privileges to do so being a new member and all. I have a computer monitor connected to the cs7 and I copied the text and pasted it below. Maybe that will help
