Kevin,

   I have not used the HB25 motor controller.  However, it sounds like it operates very similar to hobby servo motors.  I have used several of those!  They tend to like a nice steady pulse train.  The pulse [B]ON[/B] time is important but so is the pulse [B]OFF[/B] time.  It did not have to be exact in my experience; but try to make it as close as you can when starting out.  

   It is true that in the case of the hobby servos I have used I was able to obtain satisfactory performance out of them using a multiple of the specified timing durations.  However, the HB25 may need the pulse train to be very close.  I do not know.

   I suggest trying to make the pulse train close to what is stated in the motor controller manual and give it a steady and fixed pulse train to start out.  Then once you have the motor moving at some constant speed you can experiment with varying the pulse characteristics.
