Fanuc | 9900 Parameter List

Have you ever had a machine crash due to a system parameter error? Share your stories in the comments below!

You can temporarily change Parameter 9900 to a lower value (e.g., 1 or 2) to bypass missing drives while testing individual servo modules. The Workflow: Enable Parameter Write Enable (PWE) . Change 9900 to the number of drives currently connected.

If you see an option-related system alarm after changing a 9900 parameter, revert the parameter back to its original binary state using your backup file.

If you need to unlock a specific feature or clear a hardware alarm, let me know: Your (e.g., 18i-MB, 0i-TF, or 16M) The exact alarm code you are seeing

Modifying any option parameter will prompt a yellow system message: "Must Turn Off Power." You must cycle the main breaker of the machine for the changes to initialize in the system memory.

Many builders (like Mazak, Doosan, Haas, or Mori Seiki) use these macro parameters to execute complex tool changes. Changing one of these parameters might cause the tool changer arm to crash into the spindle.

An alarm will usually occur once this is enabled, which is normal. Navigate to the 9900 Series Search for "9900" using the [SRH] soft key or cursor keys. Unlocking 9xxx Parameters In some controls (like the i30), parameter 3202 bit 4

What is the (e.g., 0i-F, 31i-B)?

If a memory upgrade or mainboard replacement was recently performed, a poorly seated module or incorrect jumper configuration on the main board will trigger this alarm. 4. Step-by-Step Troubleshooting and Recovery Procedure

Unlike standard parameters (like 0000-0899) that control basic machine functions such as inch/metric mode or mirror image, the resides in a different tier of the control’s architecture.

Press the OFFSET/SETTING key, then navigate to the Setting screen.

Activating options via the 9900 parameters without purchasing the software license from FANUC constitutes software piracy. FANUC controls utilize encryptions and parity checks; unauthorized changes can lock the CNC control, requiring a factory reset or a master clear. Have you ever had a machine crash due

They act as digital binary switches that turn specific, pre-installed software features on or off.

Total system clear bypass bit (used only during severe factory resets). 3. Causes of 9900 Parameter Corruption and System Alarms

If you need help decoding a specific bit for your machine model, let me know:

Configures the look-ahead block count (e.g., 40-block, 200-block, or 400-block look-ahead functionality). 4. Macro and Programming Options Custom Macro B activation. User Macro interruption functions. Canned cycles for drilling, turning, and pocketing. How to View and Edit 9900 Parameters The Workflow: Enable Parameter Write Enable (PWE)
