Error Handling Behavior

Two outputs deal with errors that can occur while executing a function block.

These outputs are defined as:

• Error: The rising edge of Error informs you that an error occurred during the execution of the function block.
• ErrorID: Error number.
  • See PLCopen Function Block ErrorIDs.
• Done, InVelocity, InGear, and InSync mean successful completion.
  • These signals are logically exclusive to Error.
• Instance errors do not always result in an axis error.
  • Some bring the axis to StandStill.
  • See Motion State Machine.
