    Alarm wiring on Rnr motion card (Red)

    Hi.
    I have 2 drivers HBS860H. I tried to connect alarm+ from one driver to the Input 1 of the controller, then Alarm- bridged with alarm+ on the other driver and A- to DCM (gnd for24V). I added a 24V power supply for the board. But if one driver goes in alarm the other just continues to work. Does anybody have the same issue?

    Why not just connect alarm into the estop circuit if you want them all to disable when one alarms?

    Ok, I changed board. Using a standard chinese 5 axis lpt and UC100 USB , I have wired all Alm+ together to estop. All Alm- to Gnd. It works properly. Please moderator should change the board in the title. Thanks
