This parameter stores the absolute position of the machine's axes relative to the machine zero point. It is primarily relevant for machines equipped with absolute encoders, where the position must be retained even after the power is turned off.
This setting enables machine technicians to shift the reference point electronically. This removes the need to physically move limit switches or detach motor couplings during calibration. It works alongside Parameter 1815 (which sets up absolute encoders). Together, they form the foundation of a CNC machine’s coordinate system.

In Fanuc CNC systems, Parameter 1860 is a read-only axis parameter that stores the current position of the absolute position detector (absolute encoder). It is often referred to as the current position in the absolute detector or the "encoder count". Technical Overview
: It acts as the reference for the absolute position in the machine coordinate system.
: It records the current position of each axis relative to the reference point. Where: NOTE
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.
This comprehensive technical guide outlines everything an engineer, maintenance technician, or CNC operator needs to know about Fanuc Parameter 1860, its companion parameters, and how to safely navigate it during repairs. Technical Overview of Parameter 1860
Always backup your parameters before changing them. Improper settings can lead to unexpected machine movement. Enable Parameter Write: Press the [SETTING] key. Set PARAMETER WRITE=1 . It is primarily relevant for machines equipped with
To manage Parameter 1860 successfully:
Do not use Parameter 1860 to compensate for a worn ballscrew or loose coupling. Fix the mechanical problem first.
To understand how 1860 fits into the system, it is usually viewed alongside these coordinates and flags: Parameter 1815
