It does "control motion" but the industry accepted term "motion controller" always includes MUCH more functionality than this.
Didn't forget, that's where my calculation came from, and in fact it's WAY more data for a grayscale raster image. For a raster image, your step sequence is given by an acceleration ramp, a constant speed, then a deceleration ramp. Assuming that the deceleration ramp is simply a reversed acceleration ramp, and that you use the same X ramp for all rows of the image, then it only gets transmitted once and has zero "power" information.
