Parameter 1829 — Fanuc

Would you like a comparison table of Parameter 1829 across FANUC Series (0i, 30i, 31i, 18i) or a sample macro to test your current 1829 setting dynamically?

Proper lubrication and regular cleaning of the ball screws prevent the "excessive error" conditions that trigger this parameter.

To truly understand Parameter 1829, you must understand (Servo Loop Gain). Parameter 1825, measured in sec⁻¹ or (mm/min)/mm , defines how aggressively the servo corrects errors.

Position loop gain determines how aggressively a servo motor responds to a position command from the CNC.

Understanding and properly configuring this parameter is crucial for maintaining machine accuracy and preventing unnecessary downtime. This article provides a deep dive into what Parameter 1829 does, how to set it, and how to troubleshoot associated errors. What is FANUC Parameter 1829?

It acts as a safety monitor for when the machine is supposed to be stationary. Common Alarm: typically occurs if this limit is exceeded. Potential Causes of Error: Mechanical Load: Would you like a comparison table of Parameter

If the 1829 alarm happens just as the machine stops, the acceleration/deceleration time constant might be too short (too abrupt).

In FANUC CNC systems, defines the Position Loop Gain Matrix (often associated with arbitrary axis positioning or precise multi-axis interpolation).

To help diagnose your specific issue, could you share you are using (e.g., 0i-D, 31i), the exact alarm code appearing on your screen, and whether this error happens during rapid travel or a cutting cycle ? Share public link Parameter 1825, measured in sec⁻¹ or (mm/min)/mm ,

The appropriate value for parameter 1829 depends heavily on the machine type, control system, and application. The table below offers general reference ranges for common scenarios.

When you encounter this alarm, the following systematic troubleshooting steps are recommended:

Alternatively, if you'd like to share the machine's symptoms (e.g., alarm happens during tool change vs. during cutting), I can help you narrow down the issue. Share public link
