SpeedRefresh only works in a motion task. The manual shows an [example](http://developercenter.robotstudio.com/BlobProxy/manuals/RapidIFDTechRefManual/doc217.html) of updating the speed with a trap from a signal. Try adding a trap and updating the speed via a signal or shared PERS between the motion and background task. ---

The speed on the teach pendant is not indicative of the speedrefresh. They are separate overrides. ---

Good question – I am only aware of CSpeedOverride which I believe only tells you that the operator overrode the speed via the pendant but not via RAPID with SpeedRefresh… ---
