where can i download the R-30iB_basic_operator_manual_[B-83284EN_05] ?

All of these things (manuals, CAD models...) are on the official Fanuc support website, where you must be logged in.

Only if you work for a Fanuc integrator. If not, you have to buy the manuals, at about $500 a piece.

Does the R-30ia documents work for you? If you think it's helping me, Send me a message.
