E-Stop switch

Hi,

When the proper input line (pin) is triggered Mach1 initiates an E-Stop condition.

a. Is this (software triggered) the norm? I.e. shouldn't an E-Stop be a physical/mechanical/electrical sort of thing?

b. I have read mention of removing all power when E-Stop is activated and seen pictures of the Big Red Switch on several controller cabinets. Does this mean complete removal of all power to the system both AC primary and DC motor power or one or the other?

Progress is slow... and sometimes in the opposite direction!
