    When you connected the 220V are you sure you connected one Phase and one Neutral wires and not 2 phases?
    2x 220V phases would create a 340Volts DC bus voltage inside which i think is too much for this drive and then that it blew up after some time is not a surprise.
    That's not how it works in the US.

    In the US you have 3x110V or 3x220V?
