Fanuc Parameter 1860 Full ((free))

: It tracks the absolute position of each axis. This value is automatically set and updated by the CNC when an axis is zeroed (specifically through Parameter 1815 APZ ).

. This parameter is part of the axis-specific settings (1800-series) and is critical for maintaining machine coordinates without needing a reference return (homing) every time the power is cycled. Key Function & Usage fanuc parameter 1860 full

a (mm/s²) = Vc / T

Essential for systems using incremental or absolute pulse coders where the "Grid Method" is used for zero return. Why Adjust Parameter 1860? : It tracks the absolute position of each axis

In practice, for direct drive systems: $$ 1860 = \textReference Counter (1821) \div \textScrew Pitch (in pulses) $$ (Note: This varies heavily depending on whether the machine uses a Decimal Input method or the older Integer Input method.) This parameter is part of the axis-specific settings
