FANUC A16B-2203-0452 is an internal power and wiring board for Alpha SVM1-80 servo amplifier modules. FANUC documents it for compatible A06B-6079-H105 and A06B-6096-H105 single-axis amplifiers, where it forms the base power assembly used with the applicable control PCB.

The earlier wiring-board specification is A16B-2202-0762. Confirm the complete amplifier number, interface type, board revision and control PCB before replacement.

A16B-2203-0452 Product Information

SVM1-80 Power-Stage Wiring Platform

A16B-2203-0452 forms the internal power and connection platform of the compatible SVM1-80 amplifier. It supports the servo 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-H105, the board is used in a Type A/B amplifier configuration with an A20B-2001-0930 control PCB. For A06B-6096-H105, it forms the later HRV3-compatible FSSB configuration with an A20B-2100-0540-series control PCB.

Earlier Board and Replacement Checks

A16B-2202-0762 and A20B-2100-0250 are documented earlier specifications. Do not mix earlier and later boards without confirming the complete amplifier hardware. REACO CNC checks the board number, revision, terminals, connectors, solder joints and operation in a compatible SVM1-80 setup as applicable.
