Derating
■ Surrounding air temperature derating
IP21 (UL Type 1) drives and IP55 (UL Type 12) frames R1…R7
In the temperature range +40…55 °C (+104…131 °F), the rated output current is derated
by 1% for every added 1 °C (1.8 °F).
To calculate the output current, multiply the current in the ratings table by the derating
factor (k):
