50 ms sampling and self-tuning — what that means for your loop
The PXF9APP2-FBMA1: That 50 ms sampling means the controller updates its output every 50 milliseconds — fast enough to catch thermal transients in injection molding or extrusion barrel zones where a slower loop would overshoot. The self-tuning algorithm automatically sets PID parameters during the first heat-up, so you don't need to manually tune each zone on startup.
