It dictates whether the reference position is automatically updated during a reference position establishment operation (returning home).
To help give you the most accurate advice, I can provide more specific details if you share a bit more information. If you're interested, let me know:
Manually jog the axis to its physical home position (alignment marks or fixture zero).
Modifying axis parameters like 1860 can cause the machine to lose its physical orientation. To prevent crashes: Enable Parameter Write (PWE) fanuc parameter 1860
Fanuc Parameter 1860 is a critical axis-specific setting used across various Fanuc CNC control series , including the 16, 18, 21, and 0i models. It is primarily responsible for storing and managing the when an absolute position detector (absolute encoder) is used. What is Fanuc Parameter 1860?
“See?” she said, pointing. “The battery backup glitched. The amplifier forgot the offset. It thinks the rotor is 338 electrical degrees away from where it actually is. The servo is trying to correct a ghost.”
: You must set PWE to 1 on the Setting screen before changes are allowed. Verify Coordinates It dictates whether the reference position is automatically

Then, on the guide box, she pressed and INC simultaneously for three seconds.
: This parameter is set individually for each axis (X, Y, Z, etc.). Modifying axis parameters like 1860 can cause the
On older controls (0i, 16i, 18i, 21i), 1860 may be integer only; newer controls allow decimal values for fine adjustment.
Fanuc Parameter 1860 is the digital servo parameter used to set the feedback pulse count for an absolute motor encoder. It tells the CNC control how many pulses represent one full revolution of the motor. This setting is critical for maintaining accurate position data, especially after a battery failure or motor replacement. The Role of Parameter 1860
