The FANUC A860-0320-T153 is a 3000P absolute pulse coder designed for position and speed feedback in compatible FANUC CNC servo motor systems. It is an internal motor feedback encoder identified by the exact A860-0320-T153 model marking.

Its absolute-position feedback allows the CNC and servo system to monitor the motor shaft position according to the original machine configuration. For replacement, match the complete encoder model, connector, mounting interface and servo motor nameplate.

A860-0320-T153 Product Information

3000P Absolute Feedback Function

The A860-0320-T153 supplies motor-position feedback required by the servo control loop. Accurate feedback supports controlled acceleration, positioning and axis movement. Encoder failure may cause feedback alarms, unstable motion, incorrect positioning or failure of the servo axis to start.

Replacement Compatibility

Pulse coders with similar housings are not necessarily interchangeable. Confirm A860-0320-T153 on the original label and compare the feedback type, 3000P marking, connector orientation, mounting points, shaft coupling and complete servo motor model. Do not substitute A860-0320-T111, A860-0320-T013 or another A860/A290 encoder solely because it looks similar.

Testing and Installation Notes

REACO CNC checks the housing, connector, cable, bearings, feedback output and operating condition before shipment. Installation should be performed by qualified personnel. Protect the encoder from impact, oil contamination and static electricity, and complete any required reference-position or machine setup procedure after replacement.
