If “Pole Placement” method of adjustment is selected, you would enter values for
“inertia” or “inertia ratio”. Enter either one, and the other value will automatically
be entered. This is the easiest and recommended method of adjustment.
If “PI” method of adjustment is selected, you would enter values for GV--gain and
GVI--gain. This is an advanced method of adjustment, and is more difficult.
Both methods of adjustment provide identical results. PI method is described
later in this section.
