Enables circular movement across three axes simultaneously. 💡 Troubleshooting with Parameter 9900
If you change a standard parameter incorrectly, you might get an alarm or a crash. If you change a 9900 parameter incorrectly, you can instantly , make the screen go blank, or wipe out critical system options. Because these parameters configure the core hardware communication, the control may not even know how to boot up properly if they are altered. fanuc 9900 parameter list
Press the SYSTEM hard key, then navigate to the or ALL IO softkeys to back up parameters, pitch error compensation, and macro variables. Step 2: Enable Parameter Write (PWE) Press the OFFSET/SETTING hard key. Press the SETTING softkey. Change the value of PARAMETER WRITE from 0 to 1 . Enables circular movement across three axes simultaneously
Turn off the main machine breaker, wait 30 seconds for the capacitors to discharge fully, and power the machine back up. Press the SETTING softkey
The are critical system parameters found in modern CNC controls, including the FANUC Series 30i, 31i, 32i, and late-model 0i-D/0i-F platforms. Unlike standard 1000-to-8000 series parameters that control everyday machining behaviors, parameters in the 9900 range primarily govern high-level system configurations, option activation, advanced servo/spindle interfaces, and foundational machine tool builder (MTB) setups.
