FANUC A06B-0085-B003 is a βiS 22/2000 AC servo motor for compatible FANUC CNC feed-axis and industrial positioning systems. It is rated at 2.5kW and 2000rpm and combines a tapered output shaft, no holding brake and a βiA128 absolute pulse coder.

A06B-0085-B003 Specifications

βiA128 Absolute Feedback

The integrated βiA128 optical pulse coder supplies absolute position and velocity feedback at 131,072 divisions per revolution. Accurate machine operation also depends on the correct servo amplifier, feedback cable, CNC parameters and absolute-position system setup.

Exact Shaft and Suffix Configuration

A06B-0085 identifies the βiS 22/2000 motor. In B003, the first “0” specifies a tapered shaft without a brake and the final “3” specifies βiA128 feedback. With no #0100 suffix, this is the standard IP65 version. B103, B203, B303, B403 and B503 variants are not direct substitutes because their shaft or brake configurations differ.

Testing and Installation

REACO CNC checks the nameplate, tapered shaft, flange, connectors, windings, insulation, pulse-coder feedback and running condition before shipment. Confirm the complete model, taper interface, mechanical dimensions, amplifier, cables and parameters before installation. Use the correct mounting element and qualified CNC personnel to prevent shaft or bearing damage.
