Can he use a shorting contactor for an Altivar drive when the drive reaches full speed?

Issue:
Customer wants to use a shorting contactor to run the motor once the drive reaches full speed.

Product Line:

ATV61, ATV71, ATV312, ATV12, ATV32

Environment:

All models and serial numbers

Cause:

None

Resolution:

A shorting contactor cannot be used to bypass the drive like a softstart.  This would damage the IGBT's because the drive output is a PWM waveform.
