Fanuc circuit board schematics?

Check with "Al the Man" on CNCZone, in the Fanuc section. He was a Fanuc factory tech, and has a room full of old manuals. Some Fanuc stuff they were REAL cagey about, and nobody outside the factory were ever shown schematics, but other stuff was fairly available to the factory techs.

Thanks for the reply and the pointer Jon. I'll look for "Al the Man" tonight. Eric

Greetings Jon, I contacted Al and he says that he has few Fanuc schematics. But it was a good try so thanks anyway. Eric

Well, maybe NOBODY has Fanuc schematics, then. Al has sent me a bunch of scanned excerpts from manuals, but they were mostly cable connection diagrams and cross references of encoder models. Maybe I just got very lucky that some of what I needed, he happened to have. Back in the OOOLLLD days, all Fanuc controls came with a complete schematic set. But, that was maybe for 1982-vintage controls with

80186 CPUs. The newer the gear, the more secretive they became. I reverse-engineered the protocol on their serial encoders, with a little help from Al and a lot from lucky eBay buys of encoders. But, just about NO help from Fanuc. I hope you fare better.

Greetings Jon, I am thinking that nobody has the schematics too. Do you have Nobody's email adress? I am, with the help of a book, a TEK 465B 'scope, and advice from an electronics engineer friend, going to try to figure out what's wrong with the unit. Repair units are sold at a fixed price on an exchange basis, I send mine in with a check and they send me a repaired unit from off the shelf. So even if I damage the thing it more it won't cost me any more to get a replacement. Eric

Can you share me the Fanuc 0 schematic. My mail: snipped-for-privacy@gmail.com
