FANUC A17B-2100-0310 is an internal spindle amplifier driver and power board used in compatible FANUC Alpha i-B drive assemblies. A documented A17B-2100-0310/03B configuration is installed in the A06B-6222-H022#H610 αiSP 22-B spindle amplifier.
The board carries power-stage connection components such as high-current terminals, capacitors, resistors, fuses and heat-dissipation hardware. This listing is for the A17B board assembly only, not the complete A06B spindle amplifier.

Role in the αiSP 22-B Amplifier
Within the A06B-6222-H022#H610, the A17B-2100-0310 supports the spindle drive power stage and its internal electrical connections. It works with the amplifier control circuitry to deliver regulated three-phase output to the spindle motor. The voltage and current ratings above apply to the complete host amplifier, not independently to the PCB.
Replacement and Revision Checks
Confirm A17B-2100-0310, the printed revision suffix and the complete A06B amplifier model. Compare the connectors, terminal labels, fuse ratings, component positions, heat-sink structure and mounting points. A17B-2100-0311, 0312 and 0313 are separate configurations and should not be assumed interchangeable.
Testing and Installation
REACO CNC checks the board marking, terminals, capacitors, resistors, fuses, solder joints, insulation and signs of overheating, followed by functional testing in a compatible setup where applicable. Qualified personnel must isolate power and wait for the DC link to discharge before opening the amplifier.
