Description
A speed override occured beginning with this line causing an error condition which makes further speed prediction invalid. The speed prediction task has therefore entered an error handling mode within which it discontinues speed prediction but provides the actual robot speed as an output reference.
Remedy
Normal prediction will resume automatically once the speed override has propagated through the system. No further action is required. The user should avoid this during production program execution and should be aware that it may invalidate live application testing since neither the robot nor the speed prediction task are performing as programmed.
