amount while it's supposed to be stopped, shut the machine down for safety."
, then counter capacity = 4000 pulses. The CNC will think one motor rev = 4000 pulses, causing the reference point to occur twice per physical motor revolution → unstable grid.
If your system configuration uses a detection unit of , entering a value of 10000 into Parameter 1860 sets a physical deviation limit of 10.000 mm. fanuc parameter 1860 full
: The CNC automatically overwrites the data inside Parameter 1860 .
: It associates the reference position directly with the internal hardware counter value of the absolute position detector. Why You Should Not Edit Parameter 1860 Manually amount while it's supposed to be stopped, shut
Detection Units (Typically 0.001 mm or 0.0001 inch depending on basic increment settings) -99999999 to +99999999 How Parameter 1860 Interacts with the Absolute Encoders
In Fanuc CNC systems, is specifically used to define the current position (or absolute position) of each axis when using an absolute pulse coder. Function of Parameter 1860 : The CNC automatically overwrites the data inside
In FANUC CNC systems, . It works in direct synchronization with parameters 1861 and 1862 to establish and store the exact mechanical position of an axis utilizing an absolute PulseCoder.
If you have lost your reference position due to dead batteries (accompanied by APC alarms), follow this standard procedure instead of editing 1860 directly: Phase 1: Enable Parameter Writing Switch the CNC machine to . Press the OFFSET/SETTING function key.
