Ensure your RS232 cable is securely connected to the machine and PC. Set your DNC software on the PC to mode. Press the SERVICE or SYSTEM key on the FANUC MDI panel. Press the PARAM softkey.
: Often points to corrupted option parameters (the 9000-series parameters). These must be re-entered manually from the master sheet provided in the machine door cabinet. Pro-Tip: Finding Your Missing Parameter Sheet fanuc 11m parameter list
Connect an RS-232 serial cable from the machine's DB25 port to your PC (or a USB-to-RS232 adapter). Ensure your DNC software (such as Cimco, WinCNC, or NClink) is configured to match the baud rate, parity (Even), data bits (7), and stop bits (2) defined in your machine parameters (5110–5112). Step 2: Prepare the PC
You can now navigate to the parameter screen, type in your changes, and press .

How to Change Parameters Set the machine to Emergency Stop Parameter 8000 (PWE) and change it to key, then the soft key to enter the main parameter list. Type the parameter number and press (Input Number) to find it. Enter the new value and press : Set PWE back to and cycle power if required by the control. MRO Electric Reference Resources
Unlike modern FANUC controls that use four-digit parameter numbers (like 1000–9000), the FANUC 11M system uses a specific notation system typically consisting of a parameter number and a bit number (0 through 7). Use the cursor to select the specific parameter
