There are three factor of derating temperature derating, altitude derating, switching frequency derating. The load capacity decreases if the installation site ambient temperature exceeds 40 °C (104 °F) or if the altitude exceeds 1000 meters (3300 ft) or the switching frequency is changed from 4 kHz to 8, 12 or 16 kHz

Temperature Derating

In the temperature range +40 °C…+50 °C (+104 °F…+122 °F), the rated output current (I2N ) is decreased by 1% for every additional 1 °C (1.8 °F). The output current is calculated by multiplying the current given in the rating table by the derating factor.

Example If the ambient temperature is 50 °C (+122 °F), the derating factor is 100% – 1 · 10 °C = 90% or 0.90. The output current is then 0.90 · I2N.

Altitude derating, I2N

In altitudes 1000…2000 m (3300…6600 ft) above sea level, the derating is 1% for every 100 m (330 ft). For 3-phase 200 V drives, the maximum altitude is 3000 m (9800 ft) above sea level. In altitudes 2000…3000 m (6600…9800 ft), the derating is 2% for every 100 m (330 ft).
