New Original FANUC A860-2060-T321 CNC Servo Position Encoder<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The FANUC A860-2060-T321 is an \u03b1iAR128 rotary pulse coder belonging to FANUC Alpha i series servo motor encoder. It is a motor-mounted absolute encoder designed to convert rotary motion into high-precision digital position and speed feedback signals. The encoder directly communicates with FANUC servo amplifiers and CNC control systems, supporting closed-loop servo control. Widely equipped on Alpha i series servo motors for CNC machining centers, turning machines, industrial robots and automated processing equipment to ensure precise axis positioning and smooth motion operation. The supplied unit is brand-new original genuine FANUC product manufactured in Japan.<\/div>\n<\/div>\n

3. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Detect real-time rotational angle, absolute position and rotating speed of servo motor shaft.<\/li>\n
  2. Transmit digital feedback signals to servo drive and CNC controller to realize closed-loop position control.<\/li>\n
  3. Store absolute position data, avoiding repeated homing operation after power restart.<\/li>\n
  4. Support high-speed continuous rotation feedback to meet high dynamic performance of machine tool feed axes.<\/li>\n
  5. Provide reliable position signal for multi-axis linkage of CNC equipment and industrial robot joints.<\/li>\n
  6. Monitor motor operating state and feed back abnormal signal to the control system for fault alarm.<\/li>\n
  7. Guarantee sub-micron positioning accuracy for precision machining and automated handling applications.<\/li>\n<\/ol>\n<\/div>\n
    \n

    4. Technical Features<\/h2>\n<\/div>\n
    \n
      \n
