What ramifications would there be if a drive or soft start is powered on with 200 volts 400 Hz?
Line power is 200v at 400 hz.
All drives and soft starts
All models and serial numbers
The EMC filter caps that are line to line may draw too much current. If the drive has SCR rectifier for softstart, they may not work above 60 Hz. DC bus capacitors have not been evaluated for 400 Hz power.
