Re: Servo Drive - step multiplier

Hi,

On a servo, the step multiplier is marginally more useful than a
screen door on a submarine.

The only reasons for using it are:

1) You already have a high resolution encoder on a motor and a wimpy
step pulse source frequency.

2) You want to keep the "dither" angle small but otherwise don't need
a high resolution.
