Fanuc Parameter 1860 Work ((free)) May 2026

1860

Fanuc parameter (also labeled as POSCNT ) is a critical axis-specific setting used to define the position feedback pulse count for the spindle encoder. It essentially tells the CNC system how many pulses are generated for each revolution of the spindle, allowing for precise speed and position control. ⚙️ How Parameter 1860 Works

    • Example: If the encoder sends 1,000,000 pulses per revolution and the ball screw moves 10mm per revolution, the machine calculates movement based on these figures. Parameter 1860 helps define the conversion factor.

    In essence, Parameter 1860 is the "memory map" for an axis, ensuring that the physical reality of the machine matches its digital representation within the Fanuc control. step-by-step guide fanuc parameter 1860 work

    The Short Answer

    : Because it uses modular arithmetic (the value "wraps around" once it reaches its maximum limit), it continuously tracks movement over the full travel of the axis without losing its place. Important Safety Note: 1860 Fanuc parameter (also labeled as POSCNT )

    Motor

    You cannot guess this number. You must look at the label on the or the Linear Scale . Example: If the encoder sends 1,000,000 pulses per

    • A: This is normal. The physical knob position and the screen display usually show what the operator requested. Parameter 1860 limits what the CNC actually executes. To verify, look at the "Act. F" (Actual Feed) on the position screen while cutting; it should not exceed the calculated limit.
