A20B-2900-0350 Fanuc Graphic CPU Module

The A20B-2900-0350 is a Fanuc Graphic CPU Module used in F15B CAP-II CNC systems where reliable graphics processing and stable display-side control are important for normal machine operation. Identified as Module - F15B Graphic CPU, this board supports the graphics-related processing functions inside the CNC control system.

Because this model has been discontinued by the manufacturer, it is now mainly requested by customers maintaining older Fanuc-controlled equipment, replacing faulty graphic CPU hardware, or preparing spare stock for long-term support. In real maintenance work, the A20B 2900 0350 remains important because display and graphic processing problems can make the machine difficult to operate, even when other parts of the control system are still functional.

At REACO CNC, we supply dependable Fanuc parts for customers who need replacement graphic CPU modules, backup stock, or Fanuc repair support for installed CNC systems.

The A20B-2900-0350 Fanuc Graphic CPU PCB is especially relevant in F15B systems using CAP-II. Compared with a standard display board, a graphic CPU module is more closely tied to how the CNC processes and presents screen information. If this module becomes unstable, operators may experience abnormal screen behavior, graphic display issues, slow or irregular interface response, or other display-side faults that interrupt normal operation.

For many maintenance teams, replacing the correct A20B-2900-0350 is often the most practical way to restore the original graphics function without making broader changes to the control system.

This board is commonly associated with:

• Fanuc F15B CNC systems
• CAP-II applications
• Graphic CPU processing
• CNC display and operator interface support
• Maintenance and repair of older Fanuc controls
• Service work requiring original-compatible Fanuc control PCBs

It may also be sourced together with related graphic control boards, CRT modules, display boards, operator panel PCBs, main control boards, Fanuc controller parts, servo amplifier units, spindle drive units, and other CNC electronic assemblies during larger repair work.

Depending on stock availability, this board may be supplied in:

• New condition
• Refurbished condition
• Used condition

For discontinued graphics-related boards, refurbished stock is often a practical choice. It helps customers keep older CNC systems in service while controlling repair cost and lead time.

Customers usually look for the A20B-2900-0350 when they need:

• A direct replacement for a faulty graphic CPU module
• Support for discontinued F15B CAP-II hardware
• Reliable Fanuc stock for legacy CNC systems
• Access to dependable Fanuc parts for display-related repair
• Help deciding between replacement and Fanuc repair

In real production environments, graphic CPU issues can slow down both operation and troubleshooting. Operators need a stable interface to view alarms, programs, parameters, and machine status. Having the correct A20B-2900-0350 available can help restore usability faster and reduce unnecessary downtime.

REACO CNC supports both direct replacement supply and Fanuc repair inquiries. If your original A20B-2900-0350 is damaged, we can help review whether repair is practical or whether replacement is the better option based on stock, condition, and urgency.

We also support sourcing for related Fanuc parts, including graphic CPU modules, graphic control boards, display boards, CRT modules, operator panel boards, main PCBs, servo amplifier units, spindle drive units, and other CNC electronic assemblies used in installed Fanuc systems.

For many factories, older Fanuc systems are still valuable production assets. A correct A20B 2900 0350 replacement can help restore graphics processing stability, preserve the original CAP-II control structure, and avoid unnecessary system changes when the machine is still worth maintaining.
