Fanuc: 9900 Parameter List

An alarm will usually occur once this is enabled, which is normal. Navigate to the 9900 Series Search for "9900" using the [SRH] soft key or cursor keys. Unlocking 9xxx Parameters In some controls (like the i30), parameter 3202 bit 4

Enabling advanced programming flexibility, such as , interrupt functions, and specialized communication protocols (Ethernet/IP, Profibus, or FL-net configurations), relies on setting these parameters. How to View and Backup 9900 Parameters

Replace the lithium battery in the CNC control unit (usually located on the main yellow master PCB structure) with the if possible, or immediately after a shutdown to minimize data loss window. Step 2: Access the FANUC Boot System Menu fanuc 9900 parameter list

Changing these parameters can render a machine inoperable or cause unpredictable motion. Always perform a full SRAM backup before touching the 9900 series. How to Proceed

Occurs if you change a 9900 option that enables more servo axes than your physical Fanuc Servo Serial Bus (FSSB) amplifier hardware can support. Revert the parameter or check FSSB optical fiber connections. An alarm will usually occur once this is

3rd/4th axis control, Polygon turning, Spindle output switching Advanced Features Custom Macro B, Mirror Image, High-speed skip function Key Functional Bits for 9900

To help find more specific details for your machine, could you tell me the (e.g., 0i-MF, 18i-MB, 31i-B), what specific feature you want to activate, or the exact parameter number you are trying to troubleshoot? Share public link How to View and Backup 9900 Parameters Replace

In the hierarchy of FANUC CNC parameters, the represents the "nerve center" of the machine’s motion control. While standard parameters (8000s and 9000s) handle general machine data, the 9900 series specifically governs Digital Servo and Spindle Motor characteristics .

If you are replacing a Fanuc control board or reloading software, the 9900 series is part of the "Option Parameters." These tell the hardware which software features (like High-Speed Machining or 5-Axis Simultaneous Contouring) are active. Without the correct 9900-series data, your machine might "forget" it has certain capabilities. Technical Resources & Support

Unlocking additional part program storage space (e.g., extending memory from 512KB to 2MB or increasing the registerable program count from 400 to 1000) is frequently handled via these option bits. 2. High-Speed and High-Precision Machining

: Options for additional "Tape Memory" or part program storage. Advanced Machining : Enabling features like G96 Constant Surface Speed Cylindrical Interpolation High-Speed Cycle Machining System Functions
