Unlike standard parameters (100–9000 range), which control basic machine behavior like feedrates, acceleration, and axis configuration, the 9000-series parameters unlock or disable on the CNC. They determine whether your machine has high-speed machining, rigid tapping, additional axes, or even specific cycles like custom macro B.

Introduction: What Are Fanuc 9000 Parameters? If you have ever scrolled through the parameters on a Fanuc CNC control (Series 0i, 16i, 18i, 21i, 30i, or 31i), you have likely noticed a gap or a protected zone around parameter numbers 9000 through 9999. These are the Fanuc 9000 parameters , often referred to as the "hidden parameters," "option parameters," or "secret parameters." Introduction: What Are Fanuc 9000 Parameters
