    Default Soft E-Stop????

    Ok Folks:
    Time to reach out for some more cnc knowledge. I'm working on a power drawbar design and when reading over some material noted that on one design, when a drawbar error occurred, the dedicated drawbar software would throw a "soft E-stop" to the break out board. Can someone please explain the difference between a "soft e-stop" and what I am guessing would be a "hard e-stop"? Is this signal available on most popular BOB's? I'm most likely going to get some grief on the second questions since its so general but what the heck!
    Many thanks.
    Bill

    It means it's a "software" EStop, rather than a hardware EStop. An EStop signal is sent to the controller software and the controller stops everything. A hardware EStop cuts the power to however you have it rigged.

    You're very much welcome Bill.

    Noticed your sig. I was a USAF F-4 jock for most of my USAF career. I didn't go in until '82 though.

    Great Mark!
    I was ground to air radio maintenance (rapcon) and was stationed in Udorn Thailand an F4 base. Watched many of the kerosene burners launch from that runway. My hooch was in the back of the shop at the end of the flight line!
    Old memories (wow).
    Thank you for your service.
    Bill

    Bill,

    I was an avionics comm/nav tech before I got my commission and wings. The F-4 was a grand old lady. I sure do miss those days.

    Thank you and thank you for your service too!

    Mark
