Application Notes

Independent adjustable speeds

Replace the speed adjust potentiometer with a single pole, multi-
position switch, and two or more potentiometers in parallel, with
a total parallel resistance of 10K ohms. Figure 13 shows the
connection of two independent speed adjust potentiometers that
can be mounted at two separate operating stations.
