    As mentioned in your other thread, the speed is set by the width of the control pulse. The stop position is a pulse width of 1500us. The further away the pulse width is from 1500us, the faster the motor will go (up to about 1000us or 2000us). The fastest movement in one direction is with a pulse width of 1000us and in the other direction with a pulse width of 2000us. With the BS2, this corresponds to a "PULSOUT <pin>,500" or a "PULSOUT <pin>,1000" respectively.
