Load and ambient temperature classified by the Carrier Frequency
CAUTION
1) The above graph is only applied when the inverter is operated in the allowable temperature. Pay
attention to the air cooling when the inverter is installed in a panel box, and the inside temperature
should be within an allowable temperature range.
2) This derating curve is based on inverter current rating when rated motor is connected.
