A MS320 controls the master reel to a constant surface speed setpoint by slowing the motor down as the core builds. A second MS320 in the follower mode controls the traverse drive to maintain a consistent product spacing "Lay inches". This control scheme provides the operator with a quick and easy method of adjusting line speed and product spacing.
