Fanuc Parameter 1860 Best Full Guide

Must be set to use specialized backlash compensation. Parameter 1851: Backlash compensation amount (low speed). Parameter 1852: Backlash compensation amount (high speed).

On machines with tandem axes (two motors driving one large gantry), a discrepancy in Parameter 1860 between the master and slave axis will cause an immediate twist alarm or excessive current draw. Ensure both axes mirror the same calculation unless their physical gearing differs. fanuc parameter 1860 full

However, Parameter 1860 specifically interacts with the (Parameter 1821). In standard configurations (using Semi-Closed Loop control with standard encoders), Parameter 1860 is often set to 2 or calculated based on the Gear Ratio. Must be set to use specialized backlash compensation

Fanuc Parameter 1860 is a that sets the time constant (in milliseconds) for the first-order lag filter applied to the velocity command during cutting feed (G01, G02, G03) operations. On machines with tandem axes (two motors driving

It is part of the servo backlash compensation system. Its primary purpose is to address or "blips" that occur when a machine axis reverses direction. When an axis moves from a negative to a positive direction (or vice versa), there is a momentary loss of control due to mechanical gaps (backlash). Parameter 1860 provides a quick burst of acceleration during this reversal to bridge that gap instantly, minimizing the protrusion in the machined workpiece.
