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.
