FANUC A16B-2203-0454 is an internal power and wiring board for Alpha SVM1-130 servo amplifier modules. FANUC documents it for compatible A06B-6079-H106 and A06B-6096-H106 single-axis servo amplifiers, where it forms the base power assembly used with the appropriate control PCB.

This is not a standalone CNC axis-control board. Confirm the A16B number, board revision, complete amplifier model and installed control PCB before replacement.

A16B-2203-0454 Product Information

SVM1-130 Power-Stage Wiring Platform

A16B-2203-0454 forms the internal power and connection platform of the compatible SVM1-130 amplifier. It supports the amplifier power stage and interfaces with the separately installed control PCB; it is not a standalone CNC axis-control board.

Type A/B and FSSB Compatibility

For A06B-6079-H106, the board is documented with the Type A/B interface and A20B-2001-0932 control PCB. For A06B-6096-H106, it is used with the FSSB interface and A20B-2100-0542 control PCB. The earlier A20B-2100-0252 control-board specification may appear in older FSSB assemblies.

Replacement and Testing Notes

A16B-2202-0790 is listed as an earlier wiring-board specification, but revision, connectors and host-amplifier configuration must still be checked. REACO CNC inspects the board number, terminals, connectors, bus structure, solder joints and operation in a compatible SVM1-130 setup as applicable.
