I called Automation Direct this morning and spoke to one of their techs.
Confirmed what you said earlier Ed.
If the selector switch is in the off position it won't hurt anything but don't switch it while the vfd output is energized.
Using the on/off buttons on the drill will of course work, if the VFD input is hot but the stop button has been pushed its safe to use the speed selector on the drill press.
So happens that the two windings draw the same current, 5.6 amp, the motor is rated at 2.2 HP at 3390 rpm and 1.8 HP at 1640 rpm, so I don't need two sets of parameters, the rpm parameter on the VFD is cosmetic, simply used to display the motor rpm at whatever frequency.
Ordered one this morning.

Free advice is worth exactly what you payed for it.
