Fanuc Parameter 1860 Full _top_ Jun 2026

In simpler terms, it tells the servo amplifier how quickly to ramp up the motor’s rotational speed (acceleration) or ramp down (deceleration) when the CNC sends a move command while a cutting tool is engaged with the material.

controls the reference counter size for semi-closed loop axes. A "full" or correct setting ensures one motor revolution corresponds exactly to the counter’s maximum count, providing stable and repeatable reference point return. For most systems, this value is 1 when Parameter 1820 equals the encoder’s reference pulses per revolution. Incorrect values lead to positioning faults and reference point instability. Always verify with machine tool builder documentation before modification. fanuc parameter 1860 full
