4228

Requested traverse distance is not allowed

Beckhoff · TwinCAT 2 NC

What does 4228 mean?

The commanded traverse distance or looping distance for a two-speed axis is smaller than its configured braking distance. This means the axis cannot achieve the commanded move reliably, as it would require stopping instantaneously or reversing before completing the minimum necessary travel. Attempting this move can lead to inaccurate positioning or overshooting.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Adjust the motion profile parameters or the commanded distance to accommodate the axis's dynamic capabilities.

  2. 4

    Verify the braking distance parameter is correctly configured for the axis's physical characteristics.
