A20B-3300-0774 FANUC Servo Card A11 6-Axis PCB

The A20B-3300-0774 is a FANUC PC board / servo card, commonly described as a Servo A11 PCB or Servo Module A11. It is used in compatible FANUC robot or CNC control systems for servo-related control and 6-axis operation support.

This model is a FANUC servo card / servo module board, not a complete servo amplifier, complete robot controller, or complete CNC control system. Correct board number confirmation, controller compatibility checking, axis configuration checking, connector layout verification, and professional testing are important before replacement.

Product Information

Product Application

The FANUC A20B-3300-0774 servo card is mainly used for compatible FANUC robot or CNC servo control system repair and maintenance. As a Servo A11 / Servo Module A11 board, it may be required when the original servo card is damaged, unstable, burnt, corroded, or causing servo control, axis communication, motion control, or alarm-related faults.

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

Quality Control and Testing

For FANUC servo cards and servo module PCBs, careful checking is very important before shipment because PCB condition may directly affect servo control, axis movement, robot motion stability, CNC machine 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 robot and 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-3300-0774. Similar FANUC servo cards may have different hardware versions, connector layouts, controller compatibility, servo module matching requirements, axis configurations, or software requirements.

Please pay special attention to the Servo A11, Servo Module A11, and 6-axis description. If you are not sure whether this FANUC servo card is suitable for your machine, please send photos of the original board label, robot or CNC controller model, connector side photos, servo module information, machine model, and alarm details. REACO CNC can help check the details before purchase.
