Issue:
Output Current is higher than Input Current to a Drive

Product Line:
All Variable Frequency Drives

Environment:
All Variable Frequency Drives

Cause:
Basic Electrical Theory

Resoultion:
The input current may be less than the output current because the output voltage of the drive may not be equal to the input voltage.
A drive is a power converter.  The power in (Volts x Amps) will be approximately equal the power out (Volts x Amps).
When running at less than full speed the output voltage will be lower than the input voltage, which means the output current may be higher than the input current.
