Positive, actually, but that's irrelevant because the Victor speed controllers can reverse the polarity of their output in order to run the motor in reverse. In the datasheet for the chip, you'll find that it outputs 2.5V (the middle of the range) at 0Amps, and goes both positive and negative from there, 5V being some full Amperage forwards, and 0V being some full Amperage backwards.
