Fanuc Parameter 1860 Work | 2026 |
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.
It compares this value against the stored data in Parameter 1860 .
Understanding Fanuc Parameter 1860: Reference Position and Absolute Encoders fanuc parameter 1860 work
If the system detects a discrepancy between the physical position and the value in 1860, it may trigger a "Request for Reference Position Return". How Parameter 1860 Works During Startup
It is a critical, read-only system parameter used by the CNC to track exactly where an axis is relative to its reference (home) position. If the value in Parameter 1860 is lost or incorrect—often due to a battery failure—the machine will lose its "sense" of where it is, leading to homing alarms. What is the Function of Parameter 1860? If you reset Parameter 1815 but the machine
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.
When an axis is successfully homed (set with Parameter 1815.4 APZ), the current encoder count is saved into Parameter 1860. How Parameter 1860 Works During Startup It is
Most issues related to Parameter 1860 arise after a or motor replacement.
