Fanuc Parameter 1829 __exclusive__ [ EXTENDED ]
When confronted with a Parameter 1829-related alarm, follow this systematic approach:
Where:
Parameter 1829 (Positional Deviation Limit when Stopped) defines the maximum allowable error, or "lag," between the commanded position and the actual feedback position when an axis is at a standstill. Function & Purpose fanuc parameter 1829
For applications such as mold making, aerospace component manufacturing, or medical device production, maintaining tight tolerances is essential. In these cases, Parameter 1829 should be set at relatively low values to ensure the machine halts any operation at the earliest sign of a position deviation. However, this increased sensitivity also means that the machine is more likely to generate nuisance alarms from minor mechanical irregularities.
Modifying system parameters requires entering the CNC control's system configuration mode. Follow these steps carefully to adjust the values. Step 1: Enable Parameter Writing Press the mode button on the operator panel. Press the OFFSET/SETTING function key. Locate PARAMETER WRITE (PWE) on the screen. When confronted with a Parameter 1829-related alarm, follow
Last updated: October 2025 – Applicable to FANUC Series 0i-F Plus and 30i-B Series controls.
If you are seeing an alarm related to this parameter, check the following: However, this increased sensitivity also means that the
An external impact or heavy, uneven load on the table can force an axis to shift. How to Troubleshoot Parameter 1829 and Alarm 410
You will see a screen displaying Parameter 1829 for all available axes (e.g., X, Y, Z). Step 3: Edit and Confirm Cursor over to the specific axis you need to adjust. Input the new numeric value and press the softkey.
