GROUPERR_RANGE_OVERRIDETYPE

Beckhoff · TwinCAT 2 NC

What does 42EB mean?

The 'Override Type' parameter configured for the group is outside its allowed range of [1, 2]. This parameter defines the operational behavior of override functions (e.g., speed override), and an invalid type will prevent proper scaling of motion commands, leading to unexpected speeds or unresponsive overrides.

Common Causes

  • User error during manual configuration, setting the 'Override Type' parameter to a value other than 1 or 2.
  • Programmatic assignment via PLC logic or an HMI attempting to set an unsupported 'Override Type' value.
  • Loading an incompatible configuration file from another machine or an older software version.
  • System memory issue causing a corrupted 'Override Type' parameter value to be loaded during startup.

  2. 2

    2. Locate the 'Override Type' parameter for the affected NC group.

  3. 3

    3. Set the 'Override Type' parameter to either 1 (e.g., Linear Override) or 2 (e.g., Quadratic Override) as required by the application.

  4. 4
