Invalid reduction parameter for auxiliary axes

What does 42F1 mean?

The velocity reduction parameters configured for the auxiliary axes are inconsistent or invalid. These parameters dictate how the velocities of auxiliary axes are scaled relative to primary axes, and incorrect settings can result in unintended speeds, motion errors, or violations of kinematic constraints.

• A velocity reduction parameter (e.g., AuxVelocityReductionFactor) for an auxiliary axis is configured outside its valid range (typically 0.0 to 1.0).
• Inconsistent velocity reduction parameters across multiple auxiliary axes within the same NC group or kinematic chain where synchronization is critical.
• Parameter type mismatch during assignment (e.g., an integer value is written to a real number field for reduction factor).
• PLC program attempting to write a mathematically invalid value (e.g., negative) to the auxiliary axis velocity reduction parameter.
• Configuration file corruption leading to an erroneous or unparsable parameter value for auxiliary axis velocity reduction.

1. 1

   1. Open the NC group or kinematic configuration and locate the velocity reduction parameters for each auxiliary axis.

2. 2

   2. Ensure that each auxiliary axis's velocity reduction parameter is a floating-point number between 0.0 and 1.0 (inclusive).

3. 3

   3. Verify that all auxiliary axes intended for synchronized motion have consistent velocity reduction factors if required by the application.

4. 4

   4. Save the updated configuration and activate it on the controller.

5. 5

   5. Test the auxiliary axis motion at a low velocity, carefully observing actual motion versus commanded speed for discrepancies.
