Application Notes
The addition of a single pole, double-throw switch or relay contact
allows a selection of a continuously variable or a fixed maximum
speed (see Figure 4 below). This is useful in applications where a
fast return to the “home” position is desired after certain operations
have been accomplished at slower adjustable speeds.
