Body: <p>I'm trying to set a motor to spin exactly at 60rpm, and I'm using LabView for Lego Mindstorms.</p>

    <p>Power/Speed specifies the amount of power, from -100 to 100, with

  <p>So, what does the "the speed, in seconds, at which you want to move the motors." mean? I've tried setting it at one, and the motor <strong>barely</strong> moved.</p>

  So, what does the "the speed, in seconds, at which you want to move the motors." mean? I've tried setting it at one, and the motor **barely** moved.

  A speed in second makes no sense to me.
  
  Are there more information about this motor, like to maximum rpm/power ? If so, maybe that the scale from -100 to 100 is some sort of percentage of max rpm/power, with the positives being one rotation direction and the negatives the other ?
