Fanuc controls are sold with "options" (e.g., Tool Offset Measurement, Coordinate System Rotation, Custom Macro B). Historically, these were turned on via bit parameters in the 9000 series.
Here is a list of some common Fanuc 9000 parameters, grouped by category:
9000-series parameters (often ranging from 9000 to 9999 depending on the control model) primarily system options and high-level software features Input 1 and press
Because these parameters are vital to machine safety, you cannot simply type in new values. You must first enable . How to Enable Parameter Write Enable (PWE) on a Fanuc CNC
Unlike standard parameters (which might control basic functions like rapid traverse speed or metric/inch selection), the 9000-series parameters are generally reserved for system macros, option bits, and specific machine builder configurations. In many FANUC control generations—such as the Series 16, 18, and 21—parameters ranging from 9000 to 9999 act as the custodians of the machine’s unique personality. Machine tool builders (MTBs), such as Mazak, Okuma, or Haas, utilize these parameters to differentiate a lathe from a mill, or to configure specific auxiliary functions like chip conveyors, tool setters, and custom tool change sequences.

Settings that link specific G-codes or M-codes to custom O9000-series subprograms (e.g., O9001 for automatic tool changers). Key FANUC 9000 Series Parameter List & Functions 1. Macro Program Registering Parameters (G/M Code Calling)
To modify an O9000 series program (such as updating a tool changer macro coordinate), use this sequential process: Step 1: Enable Parameter Writing (PWE) Press the mode button on your operator panel. Press the OFFSET/SETTING function key. Locate the SETTING screen. Move the cursor to PARAMETER WRITE (PWE) .
