| Parameter # | Description | | :--- | :--- | | | Inferred Position Detection . Used for reference point return detection (grid shift). | | 1800 - 1802 | Servo Loop Gain . Adjusts the stiffness of the servo. Standard is usually around 2000-3000. If this is set wrong, the servo will oscillate or alarm. | | 1803 - 1805 | Motor ID Code . Identifies the specific Fanuc servo motor model (e.g., Model 10, Model 20, etc.) connected to the axis. | | 1850 - 1852 | Order 1 Servo Parameter . Often related to velocity loop gain. | | 1890 - 1892 | Order 2 Servo Parameter . Position loop gain constants. |
If your control still has parameters, perform a backup today . The old 3.6V lithium batteries on the master board typically die every 3-5 years. fanuc 11m parameter list
Below is a comprehensive guide to the Fanuc Series 11M (commonly found in older CNC controls such as 11M/11MA) parameter groups, typical parameter meanings, common values, and practical notes for setup, backup, and troubleshooting. This is a general, consolidated reference intended for technicians and engineers familiar with Fanuc controls; exact parameter numbers and available options can vary by control firmware, machine builder customizations, and specific unit revisions. Always back up parameters before changing anything and consult the specific machine’s manual or the OEM where possible. | Parameter # | Description | | :---
