Re: Question for Marriss

Jeff,

You are correct; that is the only difference. The multiplier is not
nearly as useful in the servo as it is in the step drive because you
can set resolution via the encoder. Where it is useful is:

(1) Where you need coarse resolution but still want to have a small
dither angle.

(2) You are already stuck with a high resolution encoder and have a
wimpy maximum step pulse frequency.
