    What is the ride through time for the ATV680/ATV980 active front end AFE drives?


    Issue:
    ATV680/ATV980 – What is the ride through time for the ATV680/ATV980 active front end drives?

    Product Line:
    ATV680/ATV980

    Environment:
    All

    Cause:
    Ride through time

    Resolution:

    The ATV680 and ATV980 don’t fulfil the requirements of SEMI F47.The drive systems have an internal control voltage which is generated from the mains supply via a transformer.
     If the mains voltage drops to -50% all relay and contractors will drop off.
    For the drive products it is easier to fulfil the SEMI F47 requirements, because the complete power
    supply comes out of the DC bus.
    As attachment you can find one page of the ATV980 handbook, where you can see the undervoltage specification of the ATV680/980.
