    Z-axis Brake

    The Z-axis on my Brother Drilling/Tapping center has a brake that is separate from the z-axis servo motor. My Technician has setup the drives and motors
    to energize by way of a physical switch. The plan is to turn on the control
    and bring up CamSoft (at this point the brake would be holding the z-axis in place) turn on the drives/motors with our switch which would apply power
    to our drives/motors and brake. This would release the brake and allow the
    Z-axis motor to hold the Z-axis in place.
    From here we would home the machine and go about our business.
    At days end with the Z-axis all the way up we would turn off the drives/motors and brake with our switch and the brake will hold the Z-axis in place.

    Does this sound right? Are we missing anything?
    Thanks in advance,
    Ben

    It could be done that way, personally I would prefer to do it automatically to avoid human error.
    The MO command could be burnt into the default parameters this will set the output AEN enable signals and used to turn the amps off, the brake could be activated this way also if the watch dog timer activates for a card failure, it also sets the AEN output.
    Once Camsoft is running, the SH command turns the axis on and brake off.
    This could also be integrated with the E-Stop circuit, either hardware, software or both.
