Yes, I know this is an old machine. But it welds beautifully ( or did). This is an old standby machine that had the power supply die off over the last weekend. The battery failed and the memory got corrupted. I had to do a full initiation ( and have done is many times in past for various reasons on various robots, including this one). The robot was welding perfectly before the re initialization. But after, I can advance the wire manually (with the pendant), and change the voltage going to the wire, but the arcon command does not start feeding the wire. I read an older post about this problem, but that was for a machine that was not previously known to weld. This robot was welding. I contacted Yaskawa and they thought that perhaps the CIO did not load properly (or an incorrect version), So, I re initialized it again, and the same problem. Before I start digging deep into the machine, does anyone have a suggestion? I am fully confident in the hardware. It has the big PWI board inside the door. When I manually inch the wire, a relay goes on in the sub board on the door that feeds the PWI board (that is also on the board). Upon Arcon, no other relays go on, and the gas valve does not go on. It stops on the Arcon command and times out and gives a 2020 error.
Thanks in advance,
Jeff
P.S. I have a back up somewhere, but so far I have not located it.
