Fanuc Parameter — 1829 __link__

Fanuc parameter position error limit when the axis is stopped

When an axis is "at rest," the servo motor still actively holds its position. If an external force (like gravity on a vertical axis) or a mechanical bind pushes the axis out of its designated position by more than the 1829 threshold, the control system shuts down the drives to protect the motor from overcurrent or mechanical stress.

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 Fanuc parameter position error limit when the axis

There is no single "correct" value for Parameter 1829, as it depends on the machine's construction, rigidity, load capacity, and desired precision. However, general guidelines are typically provided by machine tool builders. Share public link There is no single "correct"

Parameter 1829 sets the maximum allowable threshold for this following error while the axis is actively moving.

To understand Parameter 1829, you must first understand the position loop. A CNC servo system operates on nested feedback loops: Controls torque. Velocity Loop: Controls axis speed.
