List __top__ | Fanuc 9000 Parameters
Changing the Option Parameters (like 9920 or 9933) is strictly guarded. Unlike normal parameters, these often cannot be changed simply by flipping the PWE switch. For older controls (like the Fanuc 10/11/12), you must boot into . This is a text-based, low-level maintenance mode accessed by holding specific buttons (often - and . ) while powering on the machine. Warning: Changing 9000 option bits in IPL mode can permanently brick your CNC if done incorrectly.
This guide details the critical 9000-series parameters across common FANUC controls like the 0i-TD/MD, 16i/18i/21i, and 31i/32i/35i series. Direct Access: Key FANUC 9000 Parameters
Below is a reference list compiled across common FANUC controls (such as the FANUC 0i-MC/MD/TF, 16i, 18i, 21i, and 31i). fanuc 9000 parameters list
These are sub-programs written in Custom Macro B (or A). Unlike standard part programs, the O9000 series is used for background logic. Your machine uses O9001 to perform a tool change, or O9020 to run a probing routine. These are often hidden and locked via parameters to prevent operators from accidentally deleting or altering them.

Current loop gain for the primary servo axis. Higher values increase motor responsiveness but can cause high-frequency vibration if set too high.
Internal Option Parameter Bit allocations (Control specific options like Look-Ahead)
Used on complex multi-axis machines or turn-mills where selecting a tool requires background math, geometry adjustments, or specific sub-spindle logic.
