A860-2000-T301 and A860-2000-T321 are original FANUC spindle serial pulse encoders, essential feedback components for CNC machine spindle control system. They real-time transmit spindle rotation speed, rotation angle and one-turn reference position signals to the FANUC main control unit, supporting core functions including spindle constant speed cutting, rigid tapping, spindle positioning and C-axis contour machining.
