Some customers have asked for Force control possibility on the flexible positioning unit, so we decided to implement it. No need for cumbersome calculations, everything is handled by our software. Simply enter the requested force in Newtons (N). The internal controller calculate and control the pressure to bore size ratio, and ensure any deviations are corrected thanks to the feedback loop from the embedded pressure sensors. The high frequency of the valves will correct for leakages, load variations etc. quicker that you will notice.
