1860 — Fanuc Parameter

A: No. Spindle parameters require a power cycle. Changing 1860 without reboot has no effect.

When a CNC machine commands a rapid move (G00), the axis cannot instantly jump from zero to maximum speed. It must accelerate to that speed and then decelerate to a stop. The shape of this speed curve is determined by the Time Constant. fanuc parameter 1860

In certain FANUC control series, particularly when using rotary axes with absolute position detectors, parameter 1860 works in tandem with parameter 1861 to store and manage reference point data. When the machine coordinate passes 0 degrees or the shift value per one rotation (360 degrees or the value set in parameter 1260), the data for the reference position stored in parameters 1860 and 1861 is renewed to ensure proper following at power-on. This ensures that the system can track position across full rotations without losing accuracy. When a CNC machine commands a rapid move
