Drive types ACS580-0414A-4 and ACS580-0430A-4
In the temperature range +35…50 °C (+95…122 °F), the rated output current is derated by
1% for every added 1 °C (1.8 °F). The output current can be calculated by multiplying the
current given in the rating table by the derating factor (k):

￭ Altitude derating
At altitudes from 1000 to 2000 m (3300 to 6561 ft) above sea level, the derating is 1% for
every 100 m (328 ft). Multiply the output current given in Ratings (page 171) by the coefficient
value given in this table.
