Fanuc Parameter 1860 _hot_ May 2026

Parameter 1860 is a . Its primary function is to maintain the absolute position data provided by the encoder. When a machine uses an absolute encoder, it doesn't need to be "homed" or "zero-returned" every morning; instead, it reads the value stored in this parameter to determine its exact location.

In the world of FANUC CNC systems, is a critical setting used primarily for machines equipped with absolute position detectors . It stores the current position of each axis relative to the machine zero point, ensuring the CNC "remembers" where it is even after a power cycle. What is FANUC Parameter 1860?

Synchronizing the mechanical position of the machine with the internal coordinate system. When Does Parameter 1860 Become Important? fanuc parameter 1860

A severe impact can jump the encoder or move the physical axis, making the stored value in 1860 inaccurate. Related Alarms

2-word (often works in conjunction with high-order bits in nearby parameters). Parameter 1860 is a

Request for zero return (the system has lost its position).

You will typically need to interact with this parameter during: In the world of FANUC CNC systems, is

If the encoder batteries die, the absolute position is lost, and Parameter 1860 may need to be reset.
