Parameters List | Fanuc 9000

Often referred to as "Keeprelays" (on older models) or simply "Option Parameters," the 9000 series controls the very DNA of your machine tool. These parameters determine what features your CNC is allowed to use—from rigid tapping and high-speed machining to Ethernet connectivity and multi-axis interpolation.

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. Unlike standard parameters that adjust axis gains, backlash compensation, or I/O assignments, the 9000 series parameters act as software option switches .

If you have ever asked, "Why doesn't my machine have that feature even though it's a high-end model?" or "How do I enable a locked cycle?" — the answer lives in the . fanuc 9000 parameters list

In the world of CNC machining, FANUC controllers are the gold standard for reliability and precision. However, beneath the standard Parameters (0–999) that operators use daily lies a secretive, high-security vault: the FANUC 9000 parameters .

Changing these parameters without factory documentation can render your machine unusable or cause dangerous crashes. Part 3: The Master FANUC 9000 Parameters List (Common Reference) Note: This list is aggregated from FANUC Series 16i/18i/21i and 0i-D/F. Machine builders may alter functions. Always verify with your original machine tool manual. Often referred to as "Keeprelays" (on older models)

Disclaimer: This guide is for educational purposes. CNC parameters, especially the 9000 series, are proprietary to the machine tool builder and FANUC Corporation. Unauthorized modification may void warranties and violate software licensing agreements. Always obtain written permission and correct documentation before altering parameters.

Whether you are a shop owner trying to verify that you received the High-Speed Machining option you paid for, or a technician troubleshooting a missing G-code, understanding this list separates a basic operator from a true CNC expert. Unlike standard parameters that adjust axis gains, backlash

Create a backup of your 9000 series today. Take a photo of parameters 9000 through 9500. Store it in your cloud drive. When your machine battery dies or a technician accidentally wipes the memory, that photo is the difference between a 10-minute restore and a $10,000 service call.
