Derating based on Carrier Frequency
The continuous rated current of the inverter is limited based on the carrier frequency setting.
Parameter Cn.04 allows for adjustment of the carrier frequency. The default setting is 2 kHz or 3
kHz depending on Load type (Normal or Heavy). Refer to the following table for derating of output
current for carrier frequency settings above 4 kHz.
