With a rotational swing, it seems like you might want to typically be closer to the plate.
I believe this is likely true.
In general, you want to be...
1. Close enough to cover the Outer 1/3 of the plate.
2. Not so close you can't get the Sweet Spot on a pitch over the Inner 1/3.
My discussion of and pieces on X-Axis Adjustability explain the finer points of how to this.
You can determine this to a degree via dry swings, but I like to check (especially the Inner 1/3) using video to see exactly where on the bat contact is being made.
