    Default Servo 30 amp exploded

    I Hava a little HAAS ST-10 on the shop floor and one of my guys walked in today and told me that when he shut the machine down he heard a loud pop. I found that the main circuit breaker at the panel was tripped not on the machine. When I looked in the servo cabinet in the back of the lathe I saw IC components at the bottom and the X servo had let the magic black smoke out of it. Clearly, the servo looks shot because the traces are blown off the board see pictures below. My question to the group is can I just get a new servo and give it a shot or is there a test to make sure there is not a problem downstream? any advice would be appreciated

    There could be more wrong than just the drive that took a hit you will have to check the cables and the servo motor

    Ask him how he has been shutting down the machine???

    We checked the cables and connectors all fine, so we pulled a drive card out of a 5 axis we are running as a 3 axis and fired it up, no smoke!
    Unfortunately the controller did not power up so it turned out the mag switch for main power had a cooked leg on it. Hopefully the computer was not fried and it will work when we replace the mag switch Monday
