A-12 SP600 AC Drive User Manual
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 = 342/460 x 100% = 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.
