Changing the language of a Fanuc CNC controller typically involves adjusting settings within the system parameters. The exact steps can vary depending on the model and software version, but here is a general guide:

Step 1: Enter Parameter Edit Mode
    1.    Turn On the Machine: Start the machine and navigate to the main screen.
    2.    Switch to MDI Mode: Set the machine to Manual Data Input (MDI) mode.
    3.    Enable Parameter Write Access:
    •    Press the System or Settings key on the control panel.
    •    Locate the parameter write access setting. This is often parameter PWE (Parameter Write Enable).
    •    Set PWE to 1 (ON) to enable editing.
    ⚠️ Note: Changing parameters affects machine operation. Proceed with caution.

Step 2: Locate the Language Parameter
    1.    Find the Language Parameter:
    •    The language is typically set in parameter 3111 or a similar range depending on your controller model.
    •    Consult your controller’s manual for the exact parameter.
    2.    Check the Value:
    •    Use the arrow keys or type the parameter number (e.g., 3111) to navigate.
    •    Each number corresponds to a specific language (e.g., 0 for English, 1 for Japanese, etc.). The exact mapping is in the manual.

Step 3: Change the Parameter
    1.    Select the Parameter:
    •    Highlight the parameter using the arrow keys.
    2.    Enter the New Value:
    •    Type the value corresponding to your desired language and press Input.


Step 4: Save and Reboot
    1.    Turn Off PWE:
    •    Set PWE back to 0 to disable parameter editing.
    2.    Reboot the Controller:
    •    Power off the machine and turn it back on for the changes to take effect.
