￭ Switching frequency derating
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 Minimum switching
frequency, derate according to the table below. Changing parameter 97.01 Switching
frequency reference does not require derating.
