Switching frequency derating by derating factor
The output current is calculated by multiplying the current given in the rating table by
the derating factor given in the table below.
Note: If you change the minimum switching frequency with parameter 97.02, derate
according to the table below. Changing parameter 97.01 does not require derating.
