42F3

Invalid coupling parameter for auxiliary axes

Beckhoff · TwinCAT 2 NC

What does 42F3 mean?

The coupling parameters configured for the auxiliary axes are inconsistent. These parameters define how auxiliary axes are linked or synchronized with other axes (e.g., master-slave, gearing), and an invalid setup will lead to improper synchronized motion, position errors, or loss of coordinated control.
