Design and Performance
Bus-Plane Master Architecture for Modular System Expansion
Unlike other Series 0 main boards, the A20B-2002-0651 acts as a bus plane rather than directly housing memory, axis, and I/O functions, with peripheral boards plugging directly into it — a basic configuration typically carries three boards (memory, axis, and I/O with a PMC cassette).
Final Generation of the Pre-i Series 0 Platform
As the last generation of Series 0 boards before today’s 0i-C and 0i Mate controls, the A20B-2002-0651 represents the mature endpoint of the classic FANUC 0-Model D platform, supporting continued operation of legacy 0MD/0TD/0MF/0TF-equipped machine tools.
Scalable for Larger, More Complex CNC Configurations
Larger systems built around this master board can include a graphics processor/subsystem, additional 5th/6th axis boards, and a PMC-M board, allowing the same master board platform to scale from simple 3-axis lathes to more complex multi-axis machining centers.
Genuine Intel 486DX2 Processing for Reliable Legacy Operation
Built around the Intel 486DX2 processor standard for this generation of FANUC control, this master board provides the processing foundation for stable, predictable operation of legacy Series 0-D CNC systems.
Fully Tested Before Shipment for Reliable Replacement
Master boards of this type are fully tested on complete FANUC 0-D test rigs before shipping, supporting confidence in reliable long-term operation when installed as a replacement in your Series 0-D control system.
