Fanuc Parameter 1860 Full Fixed -

In FANUC control systems, Parameter 1860 is specifically used to define the current position of an axis when using an Absolute Position Detector

Fanuc Parameter 1860 (Position of the absolute position detector) is a read-only parameter that displays the current position value from the absolute pulse coder. While it is not a setting you typically edit manually, it serves as a critical reference point for the CNC system to maintain axis alignment without needing to re-home after a power cycle. Key Characteristics and Function Data Type: 4-word (integer). fanuc parameter 1860 full

0: The reference position is not established. The machine does not know its absolute zero, and you will likely see a "Need ZRN" (Zero Return) alarm or a 300-series absolute pulse coder alarm. In FANUC control systems, Parameter 1860 is specifically
