This article provides a comprehensive breakdown of what these parameters are, how to access them, a detailed list of common 9000 parameters across FANUC Series (0i, 16i, 18i, 21i, 31i), and critical safety warnings.
On older FANUC controls (such as the FANUC 0, 16, 18, and 21 series), the directly represented software options enabled on the control. Each parameter contained a series of 8 bits (0 or 1).
| Parameter No. | Format | Description | |:---|:---|:---| | 9000 – 9090 | Value / Bit | Base configuration (number of axes, I/O allocation, serial communication setup) |
Maps custom code characters to execute macro programs O9020 through O9029 . Step-by-Step Example: Mapping a Custom Tool Change (M06)
High-speed machining option flags and internal data server links fanuc 9000 parameters list
Used on complex multi-axis machines or turn-mills where selecting a tool requires background math, geometry adjustments, or specific sub-spindle logic.
: Often used for Option Parameters in older controls like the Fanuc 10/11/12/15M to enable features such as helical interpolation, threading, and tool length measurement.
| Parameter No. | Format | Description | |:---|:---|:---| | 3202.4 (NE9) | Bit | , 1 = editing prohibited . | | 2201.0 | Bit | Enables the output/punching of 9000 programs, 0 = punch allowed , 1 = punch prohibited . | | 3210 & 3211 | Value | Sets a password to lock/unlock the 9000 program editing function (NE9). |
In the world of precision manufacturing, Fanuc 9000-series parameters This article provides a comprehensive breakdown of what
Run hour display, parts counter functions, and custom text strings.
Because 9000-series macro programs contain the logic for your automatic tool changer (ATC) and probes, losing them during a battery failure can render your machine useless. Follow this backup procedure:
If parameter 3202 refuses to change, look for a physical key switch on the machine operator panel labeled "Memory Protect." Turn it off. To help narrow this down, please let me know: Your exact Fanuc control model (e.g., 0i-MF, 31i-B)
System option parameters (FANUC proprietary software unlock bits) Servo and Spindle Parameter Initialization (9900 Series) | Parameter No
When a FANUC control is built or retrofitted, these parameters store the identification codes for the specific motors installed. Parameter Number Description / Function Spindle motor specification selection code 9945 Servo motor specification ID code for Axis 1 9946 Servo motor specification ID code for Axis 2 9947 Servo motor specification ID code for Axis 3 The Danger of Modifying Option Parameters (9900+ / 9600+)
If you cannot see your macros on the directory page, ensure Parameter 3202 bit 4 is set to 0 . Some controllers also require Parameter 3204 adjustments to display hidden files.
Because these parameters alter the foundational logic of the CNC, they are hidden behind safety locks. To modify them, you must explicitly enable Parameter Write Enable (PWE). Step-by-Step Procedure to Modify Parameters:
Defines the starting variable number for a protected range (e.g., 500).
