    Can a shorting contactor be used with an Altivar drive when the drive reaches full speed?

    Issue:
    Can a shorting contactor be used with an Altivar drive when the drive reaches full speed?

    Product Line:
    All Altivar drives and Soft Starters

    Environment:
    All models and serial numbers

    Cause:
    Customer wants to use a shorting contactor to run the motor once the drive reaches full speed, basically using a drive as a Soft Starter

    Resolution:
    A shorting contactor cannot be used to bypass the drive like a Soft Starter. This would damage the IGBT's because the drive output is a PWM waveform. 
    Drives are meant to stay connected to and control the speed of a motor the entire time the motor is running. 
    Soft Starters can be used to ramp up a motor to full speed and then drop out to a shorting contactor.
