The FANUC A860-2005-T301 Pulse Coder is a high-precision motor encoder engineered for FANUC Alpha series servo systems. It delivers accurate feedback on motor shaft position and speed, enabling smooth and precise motion control in CNC machinery.
Manufactured in Japan under strict quality standards, this encoder ensures reliable performance, superior resolution, and long service life—making it an ideal replacement or upgrade for industrial automation systems that demand consistent feedback accuracy.
Whether used in machining centers, milling machines, lathes, or robotic axes, the A860-2005-T301 plays a critical role in maintaining tight servo synchronization and repeatable machining precision.
High-Resolution Feedback
Provides real-time, high-frequency pulse output for precise servo motor position detection.
Optimized for FANUC Alpha Systems
Fully compatible with FANUC Alpha and Alpha i Series servo motors, drives, and amplifiers.
Reliable Japanese Manufacturing Quality
Built to withstand industrial environments with resistance to vibration, oil, and dust.
Stable and Low-Noise Signal Transmission
Uses differential signal output (A/B/Z channels) for clean communication with the control unit.
Plug-and-Play Compatibility
Standardized connectors allow for easy installation or replacement with minimal downtime.
The FANUC A860-2005-T301 Encoder is widely used in:
CNC machining centers
Turning and milling machines
Servo-driven automation equipment
Robotics and motion control systems
Precision positioning applications
It is particularly valued in high-speed CNC systems where consistent feedback and dynamic response are essential for surface finish quality and tool path accuracy.
Always verify motor and encoder alignment before installation to prevent shaft stress.
Use only FANUC-certified cables and connectors for noise-free communication.
Avoid direct exposure to coolant, dust, or vibration during setup.
Periodically monitor encoder feedback signals via CNC diagnostics for stability and consistency.
Replace immediately if encountering feedback errors, drift, or pulse coder alarms on the CNC display.
This encoder measures the rotational speed and position of a FANUC servo motor. It provides pulse feedback to the CNC controller, which adjusts motor movement for accurate and smooth operation.
It is primarily designed for the FANUC Alpha and Alpha i servo motor series. Always confirm compatibility by checking the motor’s nameplate or the original encoder part number.
Common signs include axis drift, vibration, positioning errors, or encoder alarms (e.g., pulse coder feedback error). Inconsistent feedback readings or electrical noise in diagnostics often indicate encoder failure.
Yes, if you follow proper installation procedures. However, it’s crucial to align the encoder shaft precisely and use static-safe tools to avoid damaging electronic components.
The A860-2005-T301 is a later-generation encoder with improved resolution and stability, offering enhanced feedback precision for more demanding CNC applications.
