These store the machine coordinate values for the first and second reference points (Home positions). CNCMakers notes that 1240 is for the first point and 1241 for the second. I/O and Communication (RS-232)
Press the (Output) softkey, then press START . The parameters will transfer to your PC. Importing Parameters via RS-232 (Reading) Put the machine in EDIT mode. Enable Parameter Write (PWE = 1) . Press the PARAM key. Press the INPUT softkey. Send the text file from your DNC software on the PC. 5. Troubleshooting Common Parameter Alarms fanuc 11m parameter list
| Parameter | Parameter Description and Notes | | :--- | :--- | | | Setting Data : Defines basic communication code settings (ISO/EIA) and units (Metric/Inch). | | 0020 - 0023 | Input/Output Devices : Specify which physical port (RS-232, etc.) is used for foreground (MDI) and background (tape mode/DNC) communication. | | 5001 - 5003 | Communication Port Assignment : Assigns physical hardware ports (e.g., 5001=1 , 5002=1 , 5003=2 ) for different functions. | | 8000 (PWE) | Parameter Write Enable : Setting this to 1 allows parameter changes. Must be set to 0 after editing to lock parameters. | | 9001, 9002, ... | Special Function Parameters : Used by machine tool builders for ladder logic configuration. Very rarely adjusted. | | 9100 - 9132 | 9000-Series Option Parameters : These unlock "hidden" paid options in the control. They are set and displayed in hexadecimal format. | | 9400, 9500, ... | High-Level Option Parameters : Additional parameters for even more advanced options. Should never be changed without direct instruction from the MTB. | These store the machine coordinate values for the
