Fanuc 9900 Parameter List __exclusive__ Info
On modern Fanuc controls (e.g., 16i/18i/21i, 0i-MD/TD and later), these parameters are often stored on a permanent Flash ROM (FROM) card and are frequently protected. Modifying these without proper authorization or the correct options can lead to alarms like SV0401 or ALM701 . 2. Accessing and Understanding the 9900 Parameters
| Control Series | Primary Function of Parameter 9900 | Common Values & Their Meanings | | :--- | :--- | :--- | | | Defines the total controllable axes . | 3 (3-axis control, e.g., X, Y, Z) → 4 (to add a 4th axis, e.g., A axis). | | FANUC 0i MD/Mate MD | Defines total controlled axes via different parameters. | For the 0i MD model, the total control axis number is set in #8130 rather than #9900. | | FANUC 0i MF | Defines total controlled axes via different parameters. | For the 0i MF model, the total control axis number is set in #987 rather than #9900. | | General i-Series | Defines total number of axes ; a "master switch" for axis control. | Decreasing this value (e.g., from 4 to 3 ) can disable a specific axis (like a 4th axis) for troubleshooting. | fanuc 9900 parameter list

FANUC's parameters are categorized into two distinct groups. The first comprises standard, user-accessible parameters that govern the machine's day-to-day operation. The second is the highly protected group (9000 to 9999), often referred to as "secret parameters" or "function parameters". The 9900 parameter is part of this elite group, which is typically locked by FANUC Inc. and inaccessible for standard editing. These are "option parameters" that activate or deactivate specific hardware features and software options on your CNC control, serving as a digital key. They are stored in a protected area of memory, meaning they are not cleared even when performing a full memory reset or when holding down the RESET button during startup.
