FANUC A02B‑0306‑B522 – 31i‑A5 CNC Control Basic Unit

The A02B‑0306‑B522 is a core control module for FANUC Series 30i/31i/32i Model A/B CNC systems, renowned for its performance and modular design. This “basic unit” includes the main control chassis and core electronics, but requires additional PCBs, memory modules, and software inserts to become a full-featured CNC controller.

Key Features of A02B‑0306‑B522

Supports up to 4 paths and 26 total control axes (20 feed axes + 6 spindles); 31i‑A5 can simultaneously handle up to 5 axes
Modular architecture allows installation of display modules, memory, I/O boards, and other PCBs
Fan-cooled chassis ensures reliability in industrial environments
Core exchange available, with options for new or refurbished units; customers reload software and add required modules

Typical Applications of A02B‑0306‑B522

OEM integration into machining centers, milling machines, lathes, and automation systems
Retrofit and repair projects where a robust control chassis is needed
Expansion of multi-axis CNC systems in high-performance manufacturing

Main Advantages of A02B‑0306‑B522

Highly expandable – ideal as a foundational platform for building complex, tailored CNC control systems
Cost-efficient core solution – concentrate investment on electronics and software modules rather than full CNC systems
Field-proven durability – supports heavy-duty lifecycle and sustained production loads

The A02B‑0306‑B522 is a rugged, flexibly designed basis for a full-featured FANUC 31i control system. Its modularity supports easy upgrades and serviceability—perfect for OEMs, retrofitters, and maintenance professionals building or rebuilding advanced CNC infrastructures.
