The accel numbers will depend on the machine - the suggested values are just that, suggestions. You need to decide what is right for you. If your maximum velocity is 2.0 (2 inches per second, assuming an inch machine), and your accel is 4.0, then it will take one-half second to go from stopped to max speed. For some machines that might be exactly what you want. Other machines can go from zero to max speed in a tenth of a second or less. And some very massive machines may want to do it even slower.
