Product Information

Product Application

The FANUC A20B-3300-0448 axis card is mainly used for compatible FANUC F30i / 30i series CNC control system repair and maintenance. As a Servo B12 / DSP 2 axis card, it may be required when the original servo control module is damaged, unstable, burnt, corroded, or causing axis control, servo communication, or motion-related faults.

Because this is a board-level CNC axis control component, replacement should be carried out after confirming the original board number, CNC system model, axis configuration, servo system configuration, connector layout, and alarm details.

Quality Control and Testing

For FANUC axis cards and servo control PCBs, careful checking is very important before shipment because PCB condition may directly affect servo axis control, CNC machine movement, positioning accuracy, alarm status, and repair success rate. REACO CNC checks qualified products carefully and can provide real product photos or a test video before delivery when required.

Our goal is to help customers receive reliable FANUC CNC spare parts with clear product information, careful inspection, responsive after-sales support, and practical technical assistance.

Compatibility Confirmation

Before ordering, please confirm that the full board number on your original PCB is A20B-3300-0448. Similar FANUC axis cards may have different hardware versions, channel configurations, axis capacities, connector layouts, CNC system compatibility, servo configuration requirements, or software requirements.

Please pay special attention to the Servo B12 / DSP 2 / 1 Channel description and 8-axis module for F30i application. If you are not sure whether this FANUC axis card is suitable for your CNC system, please send photos of the original board label, CNC system model, connector side photos, servo configuration, machine model, and alarm information. REACO CNC can help check the details before purchase.
