The FANUC A16B-2203-0620 is a power wiring PCB for the 200V-class FANUC αiSP 22 spindle amplifier. FANUC documentation assigns it to A06B-6111-H022 TYPE A and A06B-6112-H022 TYPE B spindle amplifier configurations.
This is an internal replacement board, not a complete spindle drive. Confirm the A16B-2203-0620 label, board revision, host A06B number, connectors and installed components before ordering.

αiSP 22 Power-Stage Function
Inside the spindle amplifier, the A16B-2203-0620 carries power-stage connections between the shared DC link and spindle motor output. The complete αiSP 22 uses sine-wave PWM control to regulate spindle speed and torque. The 95A rating and operating specifications describe the host amplifier, not the bare PCB.
TYPE A, TYPE B and Generation Checks
The same board is documented in A06B-6111-H022 TYPE A and A06B-6112-H022 TYPE B, while their control PCBs differ. Confirm the complete module suffix, board revision, control PCB and sensor configuration. Do not substitute A16B-2203-0870, which FANUC assigns to later A06B-6141/6142-H022 αiSP 22 modules.
Testing and Installation Notes
REACO CNC checks the label, revision, capacitors, power devices, terminals, connectors, solder condition and spindle operation as applicable. Qualified personnel should isolate power and wait for the DC link to discharge before removing the board.
