Deratings For Special Settings In The Drive Control Program - ABB ACS580-07 Hardware Manual

If ambient temperature is below +40 °C (+104 .°F), the derating can be reduced by 1.5%
for every 1 °C reduction in temperature. Curves with derating factors from 1.00 to 0.80 are
shown below. For a more accurate derating, use the DriveSize PC tool. A few altitude
derating curves are shown below.
