Fanuc 9000 Parameters List Jun 2026

A user changed parameter 9004 on a 4-axis vertical mill thinking it would enable a 5th axis. Instead, it disabled the 4th axis, causing the machine to ignore rotary commands and crash the tool.

The 9000 list was the OEM’s ghost. Machine tool builders—Mori Seiki, Mazak, Okuma—used these parameters to lock away the machine’s true personality. A kind of factory-installed amnesia. fanuc 9000 parameters list

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. A user changed parameter 9004 on a 4-axis
