Fanuc 9900 Parameter List Jun 2026

Cross-reference your specific control model’s FANUC Parameter Manual (e.g., B-64310EN for the 30i series or B-64610EN for the 0i-F series) to confirm bit meanings.

, programs in the range of 9000 to 9099 are protected. If set to , you can view, edit, and punch them out to a PC.

Replace the lithium battery in the CNC control unit (usually located on the main yellow master PCB structure) with the if possible, or immediately after a shutdown to minimize data loss window. Step 2: Access the FANUC Boot System Menu fanuc 9900 parameter list

These parameters adjust how "stiff" or "responsive" an axis is. They determine the accuracy of cutting contours.

They dictate which G-code or M-code triggers a specific macro program. For example, if you want a custom probing routine to run whenever the machine reads a G65cap G 65
