Re: L298 goes boom - AWO?

Hey Alan,
I started the post and have gotten some very good feedback. Seems
there are some different viewpoints on EMF and unplugging motors with
the power on. For me, I'll just turn the power off :)

NOW::: can you unplug the motors if you have the AWO feautre on? The
motors are already free? OR is this still an "EMF" problem?

Thanks for the idea on the switches but on the camtronics board there
is one AWO for all 3 axis (3 axis board) and another for the single
board. I either need to fully integrate the hook up through the 3
axis one to the single axis OR use one switch with two contacts (DTSP
I think??). I ordered the parts today from Mouser and hope to get my
goodies soon. Hope to have the camtronics boards working as flawless
as they where since I started tinkering with them :)
