4463

Software end location maximum (positioning process)

Beckhoff · TwinCAT 2 NC

What does 4463 mean?

The actual position of an axis has exceeded its configured software end location maximum while active monitoring is enabled. For servo axes, this limit is extended by the parameterized following error window. This indicates an attempt to move the axis beyond its defined safe operating range, potentially risking mechanical damage or collisions.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Check the following error window parameter for servo axes; a too large value might mask overtravel.

  2. 4

    Ensure the axis is correctly homed and referenced before operation.
