FANUC Parameter 1860 is a critical axis-specific parameter used to store the absolute position data (machine coordinate) of an axis equipped with an absolute pulse coder (APC).
Introduction
Overview:
Parameter 1860 in Fanuc controls the hand number or workpiece handling configuration (often used in conjunction with hand control logic or work clamping). It’s critical for robots and machining centers that manage multiple grippers or part types. fanuc parameter 1860 work
Conclusion
If the backup battery for the Absolute Pulse Coder (APC) dies while the machine is off, the absolute position data is lost. FANUC Parameter 1860 is a critical axis-specific parameter
If you are changing 1860, you should check 1861 to ensure your machine behavior is consistent for both feed modes.
Without this correction, your rigid tapping cycles would produce out-of-tolerance threads, and your spindle would never stop at the exact same position twice. Conclusion If the backup battery for the Absolute
Reference Position Incomplete: 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.
