Fanuc A16B-2200-0391 Axis board. This PCB is a 1 or 2 channel axes Zero model C serial axes board for the 0-C controller. The 0391 comes standard as a 2 axis control board normally running in smaller CNC lathes and turning machines. The board was also sold through GE Fanuc in Europe and the America’s and is a surface mount PCB. Fitted on the later more powerful 32 bit Fanuc 0-C control systems to use Type-A interface allowing control over Fanuc ALPHA Servo amplifier series drive units 6079, 6089, 6090, 6093. Normally this card was found on late generation 0-TD, 0-TF systems post 1994 when Fanuc Japan started production of the ALPHA Modules.
DNC offer a full service for the A16B22000391 Fanuc serial axis board. Including exchange for quickest delivery or fault diagnosis, testing and repair of the axis board itself. Alternatively the complete Fanuc 0-C, 0-D, 0-F controller if at first it seems a axis card fault, but turns out to be another PCB on the system.
