The factory setting of carrier frequency varies with the AC drive power. If you need to modify
the carrier frequency, note that if the set carrier frequency is higher than factory setting, it
will lead to an increase in temperature rise of the AC drive's heatsink. In this case, you need
to de-rate the AC drive. Otherwise, the AC drive may overheat and alarm.

It is used to set whether the carrier frequency is adjusted based on the temperature. The
AC drive automatically reduces the carrier frequency when detecting that the heatsink
temperature is high. The AC drive resumes the carrier frequency to the set value when the
heatsink temperature becomes normal. This function reduces the overheat alarms.
