I think that one would have to do more than simply interrupt the steps, as that would cause the motor to slip to an unknown position (with steppers, not so with step/dir servo amps) Freezing the commanded position to the stepgen would allow the stepgen maxaccel to catch the problem, though (possibly) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
