RE: [CAD_CAM_EDM_DRO] Servo Drive - step multiplier

Very simple. If your setup of encoder resolution, reduction, and screws
require a higher pulse rate than your computer can generate to get the
max feed rate you want a pulse multiplier solves the problem. If your
encoders resolution is matched to your system so that your computer is
capable of the pulse rate required for the max feed rate you want than
you have no need for a pulse multiplier. Back when I was playing with
the original G320 prototypes I asked Mariss if there was anyway to read
the encoder in 1X or 2X mode instead of 4X to allow me to use some 1000
line encoders. His answer was to instead to multiply the input steps
with the pulse multiplier.
