In FANUC CNC systems, "9000 parameters" typically refer to system option parameters
Changing parameters—especially in the 9000 range—without proper documentation or a backup can lock you out of the control, disable critical functions, or cause the machine to behave unpredictably. Always write down the original values before making changes. fanuc 9000 parameters list
9000-series parameters typically refer to high-level system option parameters (often ranging from 9900 to 9999) that enable or disable specific software features and control configurations. Because these settings can fundamentally alter machine behavior, they are often hidden or "locked" by machine tool builders (MTBs) to prevent accidental modification.
