FANUC A16B-2203-0331 is a spindle control PCB for Alpha SPM-5.5 and SPM-11 amplifier modules. FANUC documents it for compatible A06B-6078-H206#H500 and A06B-6078-H211#H500 spindle drives.

The board works with different power/wiring boards according to the amplifier size and CE configuration. Confirm the complete drive model, PCB edition, ROM and installed power board before replacement.

Alpha SPM Spindle-Control Functions

A16B-2203-0331 provides the control platform for compatible Alpha SPM modules. It processes spindle commands, feedback and protective functions while working with the separate power board and the installed spindle software ROM.

SPM-5.5 and SPM-11 Hardware Matching

The same control-board number can be installed in SPM-5.5 or SPM-11 assemblies, but the power board changes with the amplifier capacity and CE specification. Confirm A16B-2202-0681, 0682, 0471 or 0472 on the original assembly rather than treating the complete drives as interchangeable.

ROM, Revision and Testing Notes

A16B-2202-0431 is the documented earlier control-board specification. Check the full A16B number, printed edition, A06B-6072-H500 ROM labels and drive suffix. REACO CNC tests connectors, ROM, spindle feedback, alarms and operation in a compatible SPM setup as applicable.
