4.4 InstaSPIN-MOTION Works Over the Entire Operating Range

Both the InstaSPIN-MOTION controller and the PI controller were tuned once, before executing the washing machine application. From the examples shown above, it is evident that InstaSPIN-MOTION's tuning works over the entire operating range. Whether the motor switches between the 250 rpm and -250 rpm, or maintains 500 rpm or 2000 rpm spin cycles, there is no need for new tuning sets.
