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.

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.
