A02B-0091-B501
Fanuc A02B-0091-B501 Basic Unit. This is the backplate number that has a variety of Fanuc 0 model B or Zero B control systems. Including series 0-MB, 0M-model B, FANUC 0 (digital) which is also part of the series 0-B. The master PCB is then screwed onto this backplate (there were four master boards released) and all the peripheral PCB’s are then fitted onto the master with the minimum being a PSU, and I/O PCB. This master for basic 0-MB configurations runs memory, 3 or 4 axes control, spindle control and the PMC-L (ladder).
We do not supply complete controls originally release in 1987 to 1988 – wouldn’t it be great if we could offer an out the box 0-MB or 0M-model B too sit in place of your current problem control system. If you require the complete control maybe look at retrofit options with your local CNC service engineer. However we do carry hundreds of 0-B series main Boards and peripheral or additional cards such as I/O PCB or SUB CPU Boards for punch press and very large 0-MB controlled machines.
If you do require the complete control system or repair of your A02B0091B501 then contact us to go through all the options.
