Fanuc 9000 Parameters List May 2026

The 9000 series is generally split into two distinct categories depending on the specific Fanuc Generation (i, 0i, 30i, 31i, etc.):

Fanuc service engineers have a document called "Option Parameters by Function" (B-65270EN). This is not customer-distributed but can be requested through an authorized Fanuc repair center.

| Parameter | Bit | Function | Description | |-----------|-----|----------|-------------| | 9002 | 0 | Software travel limit 2 | Additional stroke limits | | 9002 | 1 | Safe speed limit | Override clamp | | 9003 | 0 | Door lock interlock | Safety PLC integration | | 9004 | 0 | Password protection for parameters | Prevents unauthorized changes | fanuc 9000 parameters list

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.

Modern Fanuc Controls (0i-F, 30i, 31i): Fanuc stopped using simple parameters to turn options on/off to prevent piracy. Now, options are activated via a "System Option File" installed by Fanuc or the Machine Tool Builder. However, the configuration bits still exist in the 9000 range to fine-tune how those options work. The 9000 series is generally split into two

Example (Illustrative):

| Range | Common Usage | |-------|---------------| | 9000 – 9099 | Basic options (rigid tap, macro, scaling, rotation) | | 9100 – 9199 | High-speed / AI options (look-ahead, nano smoothing) | | 9200 – 9299 | Spindle and multi-axis options (C-axis, DFO) | | 9300 – 9399 | Fieldbus and communication (Ethernet, Profibus) | | 9400 – 9499 | Safety and collision detection | | 9500 – 9599 | Machine builder reserved (MTB custom) | | 9600 – 9699 | PMC (ladder) option configuration | | 9700 – 9999 | Third-party interface and future expansion | Fanuc service engineers have a document called "Option

Type 9000 and press the NO. SHIFT or SEARCH button. You will now see the hidden parameters.

Warning: Changing these parameters without factory documentation can render your machine unusable or cause dangerous crashes.
