Hi,

While reading the EMC2 documents, I think I may have missed a 
concept...  I'm wondering about the intended purpose for F2.

The docs talk about F2 "toggling the machine power".
The usage steps are always F1 (toggle estop) and then F2 (toggle power) 
- and if one just follows the recipe of F1, F2 things work...

But it seems odd to me: The names of the functions make me think the 
steps are logically reversed - as a machine that is not powered on 
should have a hard time getting out of estop.... I'd have expected the 
sequence to be "toggle power" and then "toggle estop".

So I find myself wondering what it is that F2 is supposed to toggle 
on/off....  Is there some historical aspect to the intention for F2 that 
I missed?
Perhaps someone could enlighten me as to what F2 actually does under the 
hood?

Dave
