Fanuc Parameter 1860 [portable] Full

An incorrect setting in Parameter 1860 will result in the machine moving an incorrect distance (e.g., commanding 100mm but moving 50mm or 200mm), rendering the machine unable to perform accurate machining or threading.

After a severe crash or over time, the mechanical zero may drift. Instead of moving limit switches, you can shift the reference position via Parameter 1860. However, this is a band-aid, not a repair . For significant shifts, fix the mechanics first. fanuc parameter 1860 full

This parameter sets the number of pulses required to move the axis by one unit of detection. It is part of the "Calculation of Detection Unit" formula. The CNC uses this value alongside the gear ratio and ball screw pitch to determine the "Detection Unit" (the smallest moveable distance the CNC recognizes). An incorrect setting in Parameter 1860 will result
