The Usage of "Don't pipe":
Its function is to inhibit the switched source. If they are open, the source does not give tension. 
If the short circuits, for example with a relay, the source generates the voltage to which it is regulated with the potentiometer.
There will be no problem in controlling the motor using these pins.
