Invalid parameter (auxiliary axis velocity reduction)

What does 42F6 mean?

The limit for velocity reduction of the auxiliary axes is invalid, as it must be within the interval [0.0, 1.0]. An incorrect value will cause issues with how auxiliary axis velocities are scaled, potentially leading to overspeed, underspeed, or uncoordinated motion, risking damage or poor performance.

• The parameter for auxiliary axis velocity reduction (e.g., AuxVelRedFactor) is manually set outside the allowed range of [0.0, 1.0].
• PLC program or HMI input attempts to write an invalid value (e.g., negative, greater than 1.0) to the velocity reduction parameter.
• Configuration file corruption, leading to an out-of-range value being loaded for auxiliary axis velocity reduction during startup.
• A software component is attempting to calculate and apply a velocity reduction factor that falls outside the defined limits.
• Attempting to use an older configuration with a newer NC runtime that has stricter parameter validation rules.

1. 1

   1. Open the NC group or auxiliary axis specific configuration in the development environment (e.g., TwinCAT XAE).

2. 2

   2. Locate the parameter governing auxiliary axis velocity reduction (e.g., 'AuxVelRedFactor' or similar).

3. 3

   3. Set the parameter value to be within the valid range of [0.0 ... 1.0] inclusive.

4. 4

   4. Save the modified configuration and download it to the controller.

5. 5

   5. Perform an NC reset to ensure the controller reloads and validates the corrected velocity reduction parameter.
