Fanuc 9900 Parameter List Jun 2026
Cylindrical interpolation, polar coordinate interpolation, and helical interpolation.
: Use the SYSTEM function key and then the PARAM soft key to find the 9900 series.
For Fanuc controls manufactured after 2006, these parameters are often hidden from the standard parameter screen and are instead stored in . This ensures they remain intact even if the main memory is wiped. They are typically accessed through a specific diagnostic screen rather than the standard system parameter list. Common 9900 Series Parameters

These parameters are bit-level settings where each "bit" (a 1 or 0) enables a specific software option. Parameter No. Typical Function / Feature Often sets the total number of axes enabled on the machine. 9920.0
The are critical system parameters found in modern CNC controls, including the FANUC Series 30i, 31i, 32i, and late-model 0i-D/0i-F platforms. Unlike standard 1000-to-8000 series parameters that control everyday machining behaviors, parameters in the 9900 range primarily govern high-level system configurations, option activation, advanced servo/spindle interfaces, and foundational machine tool builder (MTB) setups.
Revert the modified parameter to its original value using your backup document. System Error Alarms (Black Screen / Boot Loop) This ensures they remain intact even if the
Below is a technical breakdown of critical parameter ranges and specific bit configurations within the 9900 series. System Configuration & Software Options (9900–9919)
Configures synchronized or mirror image control across separate paths. 3. Step-by-Step Parameter Modification Procedure
Press softkey (or go to Parameter screen). Parameter No
Allows programming in radius and angles rather than traditional X-Y coordinates.
Unlike standard system parameters, 9900 series parameters (and their predecessors, the 900 series) are often protected or hidden to prevent unauthorized activation of paid features.
The Fanuc 9900 parameter list and the surrounding 6000–9000 parameters control the beating heart of your machine’s logic. Modifying them improperly can result in expensive repairs.
Boot the CNC into the boot-menu screen (hold the two rightmost softkeys below the screen while powering on) and restore the original SRAM backup file. Summary Best Practices for CNC Machinists
