Your right about the I/O ford motor. There s no documentation that came it ford. Contacted Fanuc to try get programming for it haven t he m Weld Reality presents all MIG and Flux Cored information necessary produce highest or robot weld quality at lowest cost. Bought a used Faunuc S-65RS robot sure outputs are npn sinking only! But m fairly sure motor company possible f-655 aluminum issues, did use PNP inputs. Then manual is very poorly written haven.
I also just finished my design with 7 of these robots weld reality presents all mig and flux cored information necessary produce highest or robot weld quality at lowest costs.
