Below are common 9000-series parameters found across various Fanuc models, particularly for the Fanuc 10/11/12/15M and 18MC systems: Parameter No. Bit / Setting Function Description Expansion of Simultaneous Axis 9100 Helical Interpolation (G02, G03) 9100 Skip Function (G31) 9102 Inch/Metric Conversion 9102 Canned Cycles (Drilling/Tapping) 9103 Coordinate System Rotation 9920 Fixed Cycles 9921 Program Storage Expansion (40m to 640m) 9922 Constant Surface Speed Control 9922 Custom Macro A 9925 Look-Ahead Control 9926 Automatic Tool Length Measurement Protecting and Editing 9000-Series Programs
The following list outlines common 9000-series parameters found across various Fanuc controls (e.g., 16i, 18i, 0i-MC): Fixed Cycles Tool Offset Input Inch/Metric conversion 9921.0 – 9921.4: Program Storage capacity, ranging from 40m up to 640m. Custom Macro A Helical Interpolation Look-ahead Control for smoother high-speed machining. 9926.3 – 9926.4: Tool Offset Memory to 64 or 99 offsets.

Controls whether common variables (#100–#149) clear or retain their values when the RESET button is pressed or an M30 command is executed. 3. Option Parameters (9900–9999 / "The Option String")
FANUC reading convention for bits is right-to-left, starting at 0.
| Control Series | Typical Range | Notes | |---|---|---| | | No. 900 – 939 | Often found on Series 0 and early 0i models | | Newer Models (0i‑D, 0i‑F, 30i, etc.) | No. 9900 – 9999 | Moved to avoid conflicts with other system data | fanuc 9000 parameters list
Equipped with the knowledge and parameter tables in this guide, you are now prepared to approach these hidden settings with the caution and professionalism they demand. Remember: Your machine tool—and your production schedule—will thank you.
Grace arrived two minutes later. Her face went pale, then red.
The following tables list the most common option parameters for FANUC controls, based on documentation for Series 0i and 18MC models. Use this for —always check your machine’s specific parameter manual and record the existing value before changing anything .

FANUC controllers divide parameters into ranges based on functionality. While standard parameters (1000–8000 range) handle everyday axis, speed, and feed settings, the 9000-series parameters serve two distinct purposes across different control models:

Modifying 9000-series parameters is inherently risky. Many of these bits are controlled by Fanuc and may require a specific code from the manufacturer to enable. Home - Display 9000 Programs Fanuc Parameter 3202
These are the system switches that enable or disable many of the machine's advanced capabilities. They are not standard operational parameters. They are "option parameters" that unlock features such as helical interpolation, rigid tapping, additional axes, and even the 9000 series programs themselves. Option Parameters (9900–9999 / "The Option String") FANUC
| Parameter No. | Bit / Group | Function Description | | :--- | :--- | :--- | | | Bit 2 | MPG Feed : Enables the manual pulse generator to control axis movement in feed mode. | | 9920.3 | Bit 3 | 1 MPG Control : Enables a single MPG pendant. | | 9922.0 | Bit 0 | 2nd and 3rd MPG Control : Allows the use of additional MPGs for extra axes or remote stations. | | 9920.4 | Bit 4 | Spindle S4/S5 Analog Output : Enables the analog voltage output for the spindle drive, allowing for variable speed control via M3/M4 codes. | | 9931.2 | Bit 2 | Rigid Tapping : Allows the spindle to be synchronized with the Z-axis feed to create perfect threads without a floating tap holder. |
If an instruction tells you to turn on Bit 4, ensure you are counting correctly from the right side.
In the realm of CNC manufacturing, FANUC controls are the industry standard, renowned for their reliability and versatility. While operators are typically familiar with standard G-codes and machining parameters, a more secluded and powerful layer of control exists within the system: the 9000-series parameters. The "FANUC 9000 parameters list" is not merely a data table; it represents the gateway to system-level customization, safety interlocks, and the specific behavior of machine tool builders. Understanding these parameters is essential for advanced troubleshooting and optimizing machine performance.
While exact parameters vary depending on your specific Fanuc control model, the generally dictate machine functionality. Here are some common capabilities you can unlock or configure: Example 9100-Series Option Parameters
