Fanuc Parameter 1829 Link Online

This article provides an exhaustive deep dive into what Parameter 1829 is, how it works, when to modify it, and the risks associated with improper changes.

To understand Parameter 1829, you must first understand the FANUC . fanuc parameter 1829

Two-word axis (or Word axis depending on the specific control model). Data Unit: Detection unit. This article provides an exhaustive deep dive into

Vertical machining center, FANUC 31i-B5, 3-axis. Problem: Every time the machine performed a deep helical interpolation (Z down + circular XY), the control alarmed out at the same Z depth—Alarm 411 SERVO ALARM: X Axis Excess Error. Data Unit: Detection unit

If Parameter 1829 is set too high (slow acceleration), the machine "ramps up" slowly. On a part with many tool changes and short rapid moves, the machine may never actually reach the programmed rapid rate before it has to slow down again. This "sluggish" behavior adds seconds to every part—hours to every production run. Lowering the value sharpens acceleration and reduces cycle time.
