📌 FANUC A02B‑0299‑B802 — ZERO i-B Control Basic Unit
Description:
The FANUC A02B-0299-B802 is a basic CNC control unit / operator panel chassis from FANUC’s A02B-0299 product family. It serves as the core control base (Basic Unit) for machines equipped with FANUC 0i-B / 0i-TB Series CNC controls, but is not a complete controller by itself — additional cards and software must be installed for it to operate fully.
🧠 Function & Role
-
🛠 Basic Control Unit: Acts as the foundational control module for a FANUC 0i-B/0i-TB series CNC system. It houses or interfaces with the main CPU, RAM/ROM memory, I/O modules, display/MDI boards, and other required PCBs.
-
📋 Modular Chassis: Provides physical slots and electronic backplane connections for key control electronics — essentially forming the “skeleton” of the CNC controller.
-
🧩 Needs Complementary Boards: To become a working CNC controller, this basic unit must be equipped with:
• Main CPU board (e.g., A16B-3200 series)
• Memory boards (SRAM/Flash ROM)
• I/O interface cards
• Display/MDI cards
• Option/PMC boards
• Power supply boards
…and the proper software firmware loaded.
📍 Typical Use Cases
-
🛎 Machine Tool Retrofit & Repair: Used by service technicians and machine builders when replacing or refurbishing FANUC 0i-B/0i-TB CNC controls.
-
🤝 OEM Machine Builds: Employed in new machine controller racks where FANUC 0i-B logic is required.
-
🧪 System Rebuilds: Acts as the base for full controller assembly where individual cards are added based on specific machine requirements.
📌 Important Notes
-
⚠️ Not a Complete Controller: This is a “Basic Unit”, not a full CNC system. It must be populated with the correct PCBs and firmware to function.
-
🔄 Software Reload Required: After installation, controllers built from this unit typically need the appropriate FANUC software and machine program data reloaded to match the original system configuration.
-
📦 Discontinued by FANUC: Often listed as discontinued and supplied new, refurbished, or used through third-party industrial parts distributors.
