Description
📌 Overview
The FANUC A02B‑0309‑B501 / B502 is a CNC control basic unit — essentially the core controller board for FANUC’s 0 i‑C / 0 i‑MC series CNC control systems. It’s used as the heart of the CNC controller on industrial machines such as milling machines, machining centers, and similar equipment driven by FANUC controls.
🧠 Description
-
Type: 0 i‑C CNC Control Basic Unit (controller main board).
-
Series: FANUC A02B‑0309 family — basic control unit for 0 i‑C and 0 i‑MC controllers.
-
Slots: 2 slots for optional PCBs or interface boards to expand CNC features.
-
Purpose: Acts as the central processing and control backbone that interprets CNC programs (G‑code), performs motion control, manages I/O, communicates with the operator panel, and coordinates servo/spindle drives.
⚙️ Key Features
-
Designed for 0 i‑C (compact) CNC applications where a basic control unit with expansion capability is needed.
-
Provides core CNC logic but requires additional PCBs and software to be fully operational (machine builder typically supplies the full set of boards and memory/software).
-
Often available as new, refurbished, or core exchange to support maintenance and repair.
🛠️ Applications
-
Found inside FANUC CNC controllers on machining centers, milling machines, drilling machines, and other CNC‑controlled equipment.
-
Serves as the base controller that other modules (axis control boards, I/O boards, operator interfaces) plug into.
