Hello, I posted much earlier about getting an ERC welding again. The memory got corrupted |I had to reinitialize it. When I did, I lost the arcon signal to the welder. It has the PMI weld interface in it. I went through the C I/O and it is according to the manuals, but the wiring does not match up. There are no wires on some of the terminals mentioned in the manuals. |I am getting analog signals for the voltage and amperage to the welder, I just do not know which are the arcon signal terminals. If anyone would have a schematic for either the PMI interface, or the welder, I would greatly appreciate it. Yaskawa said there may have been revisions in the c I/o that were not in the memory backup and when I restored, they did not get loaded. Yes I know this an ancient robot, but it is mounted in a complex fixture with a great deal of interface wiring. It also welds like a champ. (on the manual it notes 12 and 19 g to K and L on the welder for arc on, but the connector from the welder does not have a wire on the L terminal.
Also I am looking for either a FC2 backup up module or preferably FDDWIN with dongle that you no longer need. Yaskawa has a monsterous backlog for the latter (and also a doubled price from last summer when I first enquired).
Thanks and stay safe
Jeff
