Rockwell PowerFlex 70 User Manual

C-14 Application Notes
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 current 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
