FANUC A860-0320-T111, also searched as A8600320T111, is a 2000-pulse-per-revolution absolute pulse coder for position and speed feedback on compatible legacy FANUC AC servo motors and CNC feed axes.

GE FANUC identifies A290-0561-V531 as the ordering number corresponding to the A860-0320-T111 encoder nameplate number. A860-0320-T111 remains the primary model for visual identification, while A290-0561-V531 is included as an auxiliary parts reference.

A860-0320-T111 Product Specifications

2000P Absolute Position Feedback

The A860-0320-T111 supplies absolute motor-position feedback with a 2000P specification. In a correctly configured battery-backed FANUC system, absolute position tracking can reduce the need for reference return after CNC power is switched off and restored.

Nameplate and Ordering Number

A860-0320-T111 is the number normally used on the encoder nameplate. A290-0561-V531 is the corresponding FANUC ordering reference, not a different 2000P encoder model. Confirm both numbers when comparing quotations, stock photos and service records.

Compatibility, Testing and Installation

Confirm the complete A06B motor model, A860 encoder label, 2000P resolution, absolute feedback type, connector, cable, coupling, mounting interface and CNC/servo parameters. Do not select an encoder by housing appearance or pulse count alone. Incremental, absolute and serial pulse coders may use different interfaces.

REACO CNC checks the label, connector, mechanicalogue condition and feedback operation on an applicable FANUC test setup. Qualified personnel should record the original alignment and reference position, back up machine data, verify the battery and follow FANUC or machine-builder replacement procedures.
