Drive Full Power Range = Nominal Motor Voltage to Drive Rated Voltage + 10%.<br />
Rated current is available across the entire Drive Full Power Range<br />
Drive Operating Range = Lowest Nominal Motor Voltage - 10% to Drive Rated Voltage + 10%.<br />
Drive Output is linearly derated when Actual Line Voltage is less than<br />
the Nominal Motor Voltage<br />

Calculate the maximum power of a 5 Hp, 460V motor connected to a 480V<br />
rated drive supplied with 342V Actual Line Voltage input.<br />
Actual Line Voltage / Nominal Motor Voltage = 74.3%<br />
74.3% × 5 Hp = 3.7 Hp<br />
74.3% × 60 Hz = 44.6 Hz<br />
