In Fanuc CNC systems, Parameter 1860 (APOS) stores the absolute position of each axis
Without a correctly configured Parameter 1860, the CNC system would lose its "memory" of where the tools and workpieces are located relative to the machine bed. This parameter ensures that even if the machine is turned off for extended periods, it resumes operation with high precision, maintaining the integrity of the work coordinate systems and preventing potential mechanical crashes. fanuc parameter 1860 work
Fanuc controls often split override limits into two parameters based on the cutting mode: In Fanuc CNC systems, Parameter 1860 (APOS) stores
Defines the coordinate value of the second reference point (often used for tool changes). MRO Electric Enable Parameter Write (PWE) Relationship with Parameter 1861 Fanuc controls often split
(APC and APZ bits). Parameter 1815.5 (APC) tells the system an absolute encoder is in use, while 1815.4 (APZ) confirms the zero point has been established. When 1815.4 is set to 1, the value currently in 1860 is recognized as the valid machine position. Coordinate Calculation
