within the machine coordinate system as determined by the absolute pulse coder. en.industryarena.com Parameter Overview Parameter Number : Absolute position (Machine Coordinate) : 2-word axis parameter (Long Integer)
Here are some examples of how FANUC parameter 1860 is used in real-world applications: fanuc parameter 1860 work
Using a non-contact spindle orientation sensor, they determine the spindle is stopping 0.05mm away from true zero radially. They calculate: within the machine coordinate system as determined by
If the motor rotates in the commanded direction but the encoder reports feedback pulses in the opposite direction, the CNC control perceives this as an error. Within milliseconds, the system will detect that the axis is moving away from its target instead of toward it, triggering a safety shutdown. How Parameter 1860 Works with Other Parameters Within milliseconds, the system will detect that the
: Changing 1860 can change the Z-axis home position, directly impacting automatic tool changes (M6).
FANUC 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) .
When troubleshooting vibrations, noise, or "servo lag" errors (like Error 410 or 420), Parameter 1860 is one of the key parameters to adjust. Increasing the value makes the motion smoother but slower; decreasing it makes the motion faster but potentially jerkier. Setting and Adjusting Parameter 1860
