The 9900 range typically controls high-level system configurations. Common options found in this range include:

In Fanuc terminology, parameters in the 9900 range typically function as bit-type settings where each of the 8 bits (0-7) represents a specific machine option or software function. For example, in many controls, Parameter 9920 controls fundamental motion and interface options. Binary Value Function Description 0 00000001

While specific parameter numbers can vary slightly depending on your exact (e.g., Series 0, 16, 18, 21, or 30i), the 9900-series parameters primarily handle system-level macro argument assignments and data input/output formats. fanuc 9900 parameter list

Before editing any 9900 parameter, follow this checklist:

| Parameter | Description (Typical) | |-----------|----------------------| | | Servo motor ID for the 1st axis (X) | | 9901 | Servo motor ID for the 2nd axis (Y/Z) | | 9902 | Servo motor ID for the 3rd axis | | 9903 | Servo motor ID for the 4th axis (optional) | | 9904 | Spindle motor ID (main spindle) | | 9905 | Spindle motor ID (2nd spindle, if present) | | 9906 | High-resolution setting / pulse coder type | | 9907 | Amplifier type code (Alpha/Beta series) | | 9908 | Axis number assignment (mapping physical drives to logical axes) | | 9909 | Acceleration/deceleration time constant for spindle | | 9910 | Servo loop gain setting (related to HRV) | Can’t copy the link right now

Parameters in the FANUC 9900 system are numerical values that control various aspects of the CNC machine's behavior. These include, but are not limited to:

The 9900 series parameters are used to enable or disable specific CNC options. Unlike standard parameters (like feed rates or axis limits), these are typically set by the machine tool builder (MTB) or Fanuc based on the purchased software package. Activation

Always cross-reference your modifications with the original "Parameter Data Sheet" supplied in the back of the machine's documentation door.
