What follows is a comprehensive catalog of the 9000 series option parameters. These are primarily based on the FANUC 18MC controller, but the functions are largely transferable to other models (though the specific bit numbers may shift).
Common Fanuc 9000 Parameters Overview
The is not a single document but a flexible, machine-specific set of option switches that transform a basic CNC into a high-end machining center. While general lists exist – such as the one shared above – they are educational references, not service manuals .
While standard parameters (like axis speeds and rapid traverse rates) shape the daily operation of your machine, the 9000-series parameters are . Fanuc controllers (such as the 0i, 16i, 18i, 21i, and 31i series) use these parameters to enable or disable specific software features built into the system. fanuc 9000 parameters list
Note: This list is aggregated from FANUC Series 16i/18i/21i and 0i-D/F. Machine builders may alter functions. Always verify with your original machine tool manual.
On some controls, the MTB may have moved this option to 9500, 9900, or used a "software option table" outside the standard range. Always test with a simple macro first. If you answered to any of the above, do not proceed
FANUC reading convention for bits is right-to-left, starting at 0.
A user changed parameter 9004 on a 4-axis vertical mill thinking it would enable a 5th axis. Instead, it disabled the 4th axis, causing the machine to ignore rotary commands and crash the tool. Common Fanuc 9000 Parameters Overview The is not
