In the case of an axis error the FB MC_ReadAxisError returns error code 40001 (axis error occurred within motion controller) at its ErrorID output. At output AxisErrorID the error code of the motion controller is displayed. The associated motion controller error message texts are placed with text or XML files. All other error codes notifying internal FB-errors.
