Fanuc 9900: Parameter List
The exact function of a 9900 parameter varies by control model (e.g., 0i, 16i, 31i). Below are common examples found in standard lists: Parameter No. Description Often defines the total number of controlled axes. Tape Memory Addition (e.g., 120M). Custom Macro A activation. Spindle Speed Fluctuation Detection. X-axis Mirror Image. PMC Model selection (L, M, etc.). 200 Registerable Programs. 3. Access and Visibility Modern Controls (Post-2006)

Use the cursor keys to highlight the exact bit or integer field. Key in the new value or bit sequence (e.g., 00100100 ). Press the softkey. Step 4: System Reset Turn off the physical main power switch of the CNC machine. Wait 10 seconds for the capacitors to discharge fully. Turn the power back on.
: Change the required bit and press INPUT . A power cycle is usually required for changes to take effect. Reference Documentation
