Because these parameters sit at the core of the system architecture, you cannot change them using ordinary editing methods. Follow this strict protocol to modify or restore them safely. Step 1: Enable Parameter Write (PWE) Select the mode on your operator panel. Press the OFFSET/SETTING hard key. Locate the SETTING screen.
In Fanuc CNC systems (such as 16i, 18i, 21i, and 0i series), the are designated as Option Parameters . These control the activation of specific software features and hardware functions that are typically sold as add-on options by Fanuc. Overview of Fanuc 9900 Option Parameters
Note: Exact functions vary by FANUC series (0i, 16i, 18i, 30i, etc.). Below are the most consistent mappings.
Setting the parameters of a FANUC 9900 CNC system correctly is crucial for several reasons: fanuc 9900 parameter list
Before viewing or modifying any system files, perform an SRAM backup to a PCMCIA card or USB drive. If a parameter change corrupts the system boot sequence, an SRAM backup is the only way to restore the machine to its exact working state without a service call.
provided by the machine tool builder (e.g., Daewoo, Haas, Doosan). Alternative:
Correct parameters ensure that the machine operates efficiently and accurately, producing high-quality parts. Because these parameters sit at the core of
Set to 1:
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
Many FANUC controls require a via the PMC ladder or a G-code sequence. Common methods: Press the OFFSET/SETTING hard key
Enter the new value and validate it according to the machine's protocol.

Enables the machine to move three axes simultaneously in a helical path, which is crucial for thread milling.
