I think I understand that the PowerPro adjusts the operating speed based on load variations.
Example: Cutting hardwood rather than softwood and that this adjustment is made without operator intervention.
The powerpro has a chart function which allows you to go through functions and pick what is closes to what you are intending to do. So say you wanted to do some drilling, then you pick drill and then you can pick the size of bit, ie 1/4" or less.... /hard wood/twist drill and the other things like sawing have similar selections. The powerpro has no idea what you really have attached so it is up to you to what you tell it what you have.
Once you have selected the function and specification you "confirm". Say it had recommended a speed of 1800 rpm for that drilling operation, the 1800 is displayed and when you push the start button nothing happens because it is above the threshold of 1500 rpm so you have to confirm again to have it turn on.
So say you had your bandsaw attached and the speed was set to 10000 rpm. If you push the on button it ask you to confirm and if you do the powerpro starts your band saw at 10000.......
There is no safe guard for you being dumb. It does have that one extra step the the conventional headstock does not. Speed dial set at max and you flip the switch and away it goes, so a potential disaster is one step closer.
I do like the chart function, it gets you into the ball park on operations but sometimes I just set the speed by what I think I need or want. For example drill some pine at 1800 or 1400 doesn't really make a whole lot of difference. If I'm getting a decent hole and good chip removal I'm good to go. Like wise pushing the button for a decent saw speed is faster and easier then using the chart so that is the way I go.
Hope this helps.
