FANUC A02B-0297-B803 – Description
The FANUC A02B-0297-B803 is a basic control chassis/backplane unit used in industrial FANUC CNC (Computer Numerical Control) systems. Like other parts in the A02B-0297 series, it’s a structural backbone that holds the CNC controller’s electronic modules but does not include the electronics required to operate on its own.
📌 Key Description
-
Part Number: A02B-0297-B803
-
Type: 3-slot standalone basic control unit / chassis
-
Manufacturer: FANUC
-

-
Compatibility: Typically used with FANUC Series 18i-MB / 180i / 180i-SB and similar CNC platforms where a modular control rack is required.
🧠 Function & Features
-
Chassis/Backplane: Acts as the main framework for installing control electronics.
-
3 Slots: Allows multiple boards to be inserted for CPU, axis control, I/O expansion, communications, etc.
-
No Electronics Included: Ships as a bare backplane housing; CPU cards, interface modules, and software must be installed to make a functional CNC system.
-
Industrial Design: Built to withstand typical factory and machining environments.
🛠️ Typical Usage
This chassis is commonly used for:
-
Machine tool OEMs – customizing control systems.
-
Retrofit projects – rebuilding older FANUC CNC controllers.
-
Service & Maintenance – as a spare to rapidly replace failed control chassis.
