help with motor drive

hello i just started to use arduino and its my first project.
i have a motor driver IMS-2

and a Potentiometer
i didnt find a video or a guide to explain the connections of the driver…
can someone explain it or sent me a guide plz:)

Here is one post within the forum, that may help

and datasheet for the IMS-1

Its been a while working with my motors and driver, but i do remember that it was not obvious what needed to be done, atleast for me.. but i did get it working and then i stopped working on that project..
