42F2

Invalid dynamic parameter for auxiliary axes

Beckhoff · TwinCAT 2 NC

What does 42F2 mean?

The dynamic parameters (e.g., acceleration, deceleration, jerk) configured for the auxiliary axes are inconsistent. These parameters govern the motion behavior and responsiveness of auxiliary axes, and inconsistent values can lead to jerky movements, overshooting, or exceeding mechanical limits during coordinated operations.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Adjust parameters as needed to achieve smooth and controlled motion.

  2. 4

    Save configuration changes and restart the NC system.
