Fanuc Parameter 1860 Work Exclusive [1080p • 720p]

The CNC reads the current value from the encoder.

Because Parameter 1860 is a system-generated value, you do not "type in" a value manually. Instead, you perform a procedure to let the CNC update it: fanuc parameter 1860 work

Understanding Fanuc Parameter 1860: Reference Position and Absolute Encoders The CNC reads the current value from the encoder

In Fanuc CNC systems, Parameter 1860 acts as the machine's memory for when using absolute pulse coders (APC). Unlike incremental encoders, which must hit a "limit switch" or "dog" every time the machine starts up, absolute encoders always know their position. Unlike incremental encoders, which must hit a "limit

When an axis is successfully homed (set with Parameter 1815.4 APZ), the current encoder count is saved into Parameter 1860.

If they match within a certain tolerance, the machine "remembers" its position immediately without requiring a manual zero return. Troubleshooting Common 1860 Issues

These indicate that the absolute position data has been lost.
