FANUC A17B-2100-0794 is an internal servo amplifier power baseplate / power PCB associated with the A06B-6320-H364 Beta i-B combination servo and spindle amplifier. It provides the mechanical mounting and internal power interconnection required by the host amplifier assembly.

This item is the A17B-2100-0794 board assembly only, not a complete servo amplifier and not a Profibus communication board. Confirm the exact board number, host amplifier model, revision, power-contact arrangement and mounting pattern before ordering.

A17B-2100-0794 Product Information

Role in the βiSVSP Amplifier

The power baseplate supports high-current internal connections and installed power components within the A06B-6320-H364 amplifier. The host unit is identified as βiSVSP80/80/80-18-B, a combination servo and spindle amplifier rather than a five-axis drive. Ratings shown above apply to the complete host amplifier, not independently to this board.

Replacement and Compatibility

Match A17B-2100-0794 and A06B-6320-H364 against the original labels. Also compare the board revision, connectors, bus contacts, mounting points, installed components and surrounding amplifier hardware. Similar A17B-2100 boards and other A06B-6320 amplifier variants are not automatically interchangeable.

Testing and Installation

REACO CNC checks the board marking, substrate, power contacts, terminals, solder joints, insulation condition and signs of overheating, followed by functional testing where applicable. Qualified personnel should isolate the machine, wait for the DC bus to discharge and follow FANUC service procedures before removing the amplifier or internal board.
