The drive acceleration dynamics can be adapted to the sewing machine characteristic (light/heavy).
 High setting value = high acceleration
With a high starting edge setting and, in addition, possibly high braking parameter values on a light machine, the
characteristic may appear coarse. In this case, one should try to optimize the settings.
