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.

Complete Troubleshooting Guide

  1. 1

    Check the dynamic parameters (acceleration, deceleration, jerk) for auxiliary axes in the NC configuration.

  2. 2

    Ensure all parameters are valid, consistent with each other, and within the physical capabilities of the auxiliary axes.

  3. 3

    Adjust parameters as needed to achieve smooth and controlled motion.

  4. 4

    Save configuration changes and restart the NC system.
