Example:
Calculate the maximum power of a 5 HP, 460V motor connected to a 480V rated drive supplied with
342V Actual Line Voltage input.
•
Actual Line Voltage / Nominal Motor Voltage = 74.3%
•
74.3%
× 5 HP = 3.7 HP
•
74.3%
× 60 Hz = 44.6 Hz
At 342V Actual Line Voltage, the maximum power the 5 HP, 460V motor can produce is
3.7 HP at 44.6 Hz.

Drive Full Power Range = Nominal Motor Voltage to Drive Rated Voltage +10%.
Rated power is available across the entire Drive Full Power Range.
Drive Operating Range = Lowest (*) Nominal Motor Voltage –10% to Drive Rated Voltage +10%.
Drive Output is linearly derated when Actual Line Voltage is less than
the Nominal Motor Voltage.
