Fanuc 9900 Parameter List ((full)) Jun 2026

Modifying these parameters is high-risk and usually requires specific authorization because they govern the control's core capability. Fanuc Parameter Options Overview | PDF | Computing - Scribd

| Bit | Function | |------|------------| | #0 | 0 = 3 axes max, 1 = 4 axes or more | | #1 | 0 = No Cs contouring, 1 = Cs contouring enabled | | #2 | 0 = No spindle sync, 1 = Spindle synchronization (e.g., rigid tapping) | | #7 | Master/slave axis pairing |

: These parameters often do not appear on the standard parameter screen and are instead hidden within a diagnostic screen.

Among these, the hold a unique and critical position. This article provides an in-depth breakdown of what the 9900 parameters do, how to interpret them, and how to safely manage them on your CNC machinery. What Are FANUC 9900 Parameters? fanuc 9900 parameter list

Drop a comment below with your control model (e.g., 0i-MD or 18i-TB) and the specific behavior you're trying to adjust!

Always back up your existing parameters before touching the 9900 range.

: Parameters like 9921 control part program storage capacity, ranging from 40m to 640m. Modifying these parameters is high-risk and usually requires

The FANUC 9900 series parameters represent a critical yet restricted set of configuration data within FANUC CNC (Computer Numerical Control) systems. Unlike standard parameters (1000–9000), the 9900 range governs high-level hardware configuration, axis linkage, and software option enablement. This paper provides a comprehensive list of common 9900 parameters, explains their functional domains, details the security protocols required for modification, and outlines safety procedures to prevent unrecoverable machine states.

If you want, I can:

⚠️ : The table above provides common examples from user forums and guides. The exact function and valid values for your 9900 parameter may differ. Modifying it can cause alarms (e.g., servo alarms) and will not allow you to unlock paid options without proper authorization. This article provides an in-depth breakdown of what

To change any parameter, the Parameter Write Enable (PWE) must be set to 1: [OFFSET/SETTING] PARAMETER WRITE=1 (Ignore the alarm P/S 100). page to make changes. After changes, set PARAMETER WRITE=0 Turn the power off and back on. 5. Troubleshooting Lost Options
