Description
x📌 FANUC A16B-3200-0391 — i B Stand-Alone Control RISC PCB
A16B-3200-0391 is a stand-alone control printed circuit board (PCB) used in industrial FANUC CNC systems as a core processing board. It belongs to the A16B-3200 series of FANUC control electronics, which are designed to manage the main control logic in i-series controllers.
🧠 What It Does
-
🧩 RISC Control Board: This is a control PCB built around a RISC (Reduced Instruction Set Computer) architecture, which provides efficient, reliable processing power for CNC operations.
-
🔌 Standalone Control: It can operate as a standalone controller board, meaning it performs the central processing and execution functions in the CNC cabinet without needing a separate CPU board.
-
🛠️ CNC Logic & Communication: The board handles core CNC system logic, timing, data exchange, and communication between other modules (like memory, I/O, servo, and display boards) within the controller.
-
📍 Robust Design: Built to operate under typical industrial conditions (e.g., up to ~55 °C working temperature, specific humidity constraints).
📋 Typical Use
This board is used in FANUC Series 16 and similar control systems where a standalone RISC processor module is required — for example, older series CNC controllers that don’t use the later “B” series A20B CPU modules.
📌 Notes
-
Core Exchange: Many suppliers require a core exchange when purchasing this board, meaning you return your old unit for credit.
-
Repair/Refurbishment: Some vendors offer refurbished units with testing and warranty — beneficial when original FANUC new stock isn’t available.
-
Industrial Part: It’s a legacy board used in industrial CNC systems — not a consumer product — so installation and parameter configuration should usually be done by someone experienced with FANUC controller hardware.
