1860 Work 'link': Fanuc Parameter

These indicate that the absolute position data has been lost.

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:

If you reset Parameter 1815 but the machine doesn't move to the correct spot, the value in 1860 will often change automatically once a new reference point is established. fanuc parameter 1860 work

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

The CNC reads the current value from the encoder. These indicate that the absolute position data has been lost

It typically uses modular arithmetic, meaning the value "wraps around" based on the encoder's pulses per revolution.

Understanding Fanuc Parameter 1860: Reference Position and Absolute Encoders If they match within a certain tolerance, the

When you power on a Fanuc machine equipped with absolute encoders:

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.
