Fanuc Parameter 1829 |top| Jun 2026

When an axis is stationary, the CNC control continuously monitors the difference between the "commanded" position and the "actual" position reported by the encoder.

While a "quick fix" is often to just increase the value in 1829, this can mask serious mechanical problems. Use this adjustment as a diagnostic tool rather than a permanent solution. How to Enable Parameter Write Enable (PWE) on a Fanuc CNC fanuc parameter 1829

(often DGN 300 or similar) to watch the "error" or "position deviation" in real-time. If it sits near the 1829 limit while idle, a mechanical problem is likely Enabling Changes: If you must adjust the parameter, you will need to enable Parameter Write Enable (PWE) Setting screen Key Related Parameters Parameter 1828: Defines the allowable error while the axis is (interpolating). Parameter 1826: When an axis is stationary, the CNC control

Always verify that 1829 is mathematically compatible with your machine’s maximum rapid and loop gain. How to Enable Parameter Write Enable (PWE) on

Input is in "Detection Units" (typically 0.001mm or 0.0001 inch).
