So do FanAmps start full powered then to set speed (by onboard dials or input signal)

Also, is it safe for a pump's speed to be changed by voltage? Not sure how other pump controllers or a pump's own onboard circuitry does it. If it's safe, putting a FanAmp between a D5 and analog fan controller seems pretty awesome.
