Invalid dynamic parameter for auxiliary axes

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.

• Acceleration, deceleration, or jerk parameters for an auxiliary axis are configured to zero, negative, or undefined values.
• Inconsistent dynamic parameters between master and slave auxiliary axes, or within a coupled group where coordinated motion is expected.
• Parameter values exceeding the physical limits of the auxiliary axis servo drive or the mechanical system it controls.
• Mismatch in dynamic parameter units (e.g., mm/s^2 vs. rev/s^2) across different configuration sections of the NC system.
• PLC logic assigning dynamic parameters that lead to mathematical inconsistencies within the kinematic model for auxiliary axes.

1. 1

   1. Access the NC group configuration and specifically check the dynamic parameters (acceleration, deceleration, jerk) for each auxiliary axis.

2. 2

   2. Ensure all dynamic parameters are positive, non-zero values and within the limits specified by the auxiliary axis drive datasheet.

3. 3

   3. Confirm consistency of dynamic parameters across all auxiliary axes within the same kinematic group where coordinated motion is required.

4. 4

   4. Download the corrected configuration to the controller and perform an NC reset.

5. 5

   5. Perform a low-speed test run of the auxiliary axes, monitoring their actual acceleration and deceleration profiles via scope or diagnostic tools.
