The FANUC A860-2070-T321 Servo Encoder is a precision-engineered pulse coder designed to provide accurate rotational feedback for FANUC Alpha and Alpha i series servo motors. Built in Japan under strict FANUC manufacturing standards, this encoder guarantees exceptional signal stability, resolution accuracy, and long-term reliability — making it an essential component in high-performance CNC systems.
This model is commonly used in CNC machining centers, milling machines, lathes, and industrial robots, where precision motor feedback directly influences machining accuracy and surface finish. As part of FANUC’s advanced feedback system, the A860-2070-T321 delivers real-time position and velocity data to the servo drive, ensuring seamless motion synchronization and optimal machine performance.
High-Resolution Position Feedback
Provides accurate pulse output for precise motor shaft tracking, ensuring smooth axis control and zero-lag servo response.
Optimized Compatibility
Designed specifically for FANUC Alpha / Alpha i servo motors, ensuring easy installation and perfect communication with FANUC drives and control units.
Industrial-Grade Durability
Built to withstand vibration, oil mist, temperature fluctuations, and continuous industrial use in demanding environments.
Reliable Signal Integrity
Differential A/B/Z output ensures consistent signal transmission with minimal electrical noise interference.
Maintenance-Friendly Design
Compact and lightweight for quick installation, alignment, and replacement during equipment maintenance cycles.
The FANUC A860-2070-T321 Encoder is used in a variety of precision motion control systems, including:
CNC Machining Centers — For axis positioning and spindle speed monitoring
Turning & Milling Machines — For precise rotational feedback and synchronization
FANUC Robots & Automation Equipment — For dynamic movement control
Servo Motor Feedback Loops — In Alpha and Alpha i drive systems
Industrial Automation Lines — For high-speed, closed-loop positioning
Its superior reliability makes it the preferred choice in industries such as aerospace, automotive, precision tooling, and semiconductor manufacturing.
Ensure proper shaft alignment and coupling tolerance when installing to avoid mechanical load on the encoder bearings.
Use shielded and grounded cables to prevent EMI-induced signal distortion.
Keep the encoder’s optical components clean and protected from coolant or oil contamination.
Periodically check pulse output consistency using CNC diagnostic tools.
Replace immediately if the CNC reports feedback signal errors or servo alarm codes related to the pulse coder.
It functions as a pulse coder, converting motor shaft rotation into electronic signals. These signals allow the CNC controller to measure motor speed and position in real time for precise control.
While both encoders belong to the same Alpha i family, compatibility depends on the motor model and control version. Always verify using your servo’s nameplate and system manual before replacement.
Typical causes include wiring faults, encoder misalignment, or internal signal failure. Check cable continuity, connector condition, and encoder output on diagnostic screens.
Yes. The A860-2070-T321 can be installed on both new and refurbished FANUC Alpha or Alpha i servo motors, provided mechanical and electrical specifications match.
With proper installation and maintenance, the service life often exceeds 8–10 years in standard industrial conditions.
