This parameter defines the allowable margin of error (dead zone) between the and the actual position of the machine axis when the movement is supposed to be finished. This parameter sets the maximum allowable error (distance)

If an axis (like a vertical Z-axis) drops slightly due to gravity after the brakes or servos are disabled. en.industryarena.com How to Modify (General Procedure)

Parameter 1829 is a fundamental "gatekeeper" of CNC stability. By establishing a strict limit for how much an axis can stray while idle, it protects the workpiece, the tooling, and the operator from the consequences of mechanical drift and electrical instability. Understanding its function allows for faster diagnostics and ensures that the CNC system remains a high-precision instrument rather than just a collection of mechanical parts.

This parameter sets the maximum allowable error (distance) between where the control system thinks an axis is and its actual physical position while the machine is at rest. If the deviation exceeds this value, the control triggers a 410 Servo Alarm (Excess Error Stop). en.industryarena.com Key Function & Troubleshooting
