Fanuc 9000 Parameters List Access
Parameters 9000–9999 are typically bit parameters (0 or 1). Each "bit" activates a specific function.
Parameters in the 9100 range and higher (up to 9999) are locked with a higher level of security that cannot be bypassed by setting PWE=1.
These are custom macro programs that control almost every automated machine function on your CNC. They are written by the machine tool builder (MTB) to manage operations like the automatic tool change (ATC), probing routines, pallet changers, and other specific machine logic. Unlike standard part programs, these are often hidden and protected from accidental editing.

0 = 9000-series programs are unlocked, visible, and editable. Fanuc 0-M / 0-T (Older Legacy Controls) 1 = 9000-series programs are protected. 0 = 9000-series programs are open for editing. Fanuc 10M / 11M / 12M Parameter 2201 Bit 0 (NE9) 1 = 9000-series programs are locked. 0 = 9000-series programs are unlocked. Related 8000-Series Program Parameters
: Never change any parameter unless you have a verified backup of all system data and you are following a documented procedure from the machine tool builder or FANUC.
Incorrect values can cause the CNC boot loop or freeze. Parameters 9000–9999 are typically bit parameters (0 or 1)
If you need to view or edit the macro programs (O9000–O9999) rather than the system parameters, you must change Parameter 3202, bit 4 (NE9)
1 = 9000-series programs are locked and hidden (Factory Default).
On legacy controls like the FANUC 0M, 0T, 6, 10, and 11, the 9000-series parameters directly enable optional software features purchased from the builder. These are custom macro programs that control almost

Ensure the machine is safely at a standstill and switch the mode selector dial to MDI (Manual Data Input). Enable Parameter Write (PWE): Press the OFFSET/SETTING hard key. Locate the SETTING softkey on the screen. Find the field labeled PARAMETER WRITE (or PWE ). Change the value from 0 to 1 .
