Because machine tool builders often remap or lock 9000 parameters, changing them arbitrarily can cause:
Parameters allow you to assign a custom M‑code number to execute a specific 9000‑series program. For example, to have M91 call program O9001 , you set parameter 6071 to a value of 91 . The parameters 6071–6079 correspond to O9001–O9009 in sequence.

Depending on your specific control model (e.g., Series 0, 10, 15, 18, 31i), these parameters vary. Below is a list of common system and option parameters found in the 9000 range: fanuc 9000 parameters list

Maps an M-code number to call programs O9001 through O9009.
: If a technician formats the program directory or deletes macro files while NE9=0 , the O9006 tool change macro could be permanently deleted. Executing an M06 afterward will result in a CNC alarm or an unguided mechanical crash. Because machine tool builders often remap or lock

Occurs if an option parameter in the 9000 range was entered incorrectly. Immediately revert to your backed-up value.
In most Fanuc controls (such as the 0, 10, 11, 15, 16, 18, and 21 series), parameters in the 9000 range are typically reserved for . These are often bit-based, meaning a single parameter number (e.g., 9100) contains 8 individual bits (0 through 7) that each toggle a different machine capability.
