If the carrier frequency is low, output current has high harmonics, and the power loss and
temperature rise of the motor increase.
If the carrier frequency is high, power loss and temperature rise of the motor declines.
However, the AC drive has an increase in power loss, temperature rise and interference.
Adjusting the carrier frequency will exert influences on the aspects listed in the following table.
Influences of carrier frequency adjustment
Carrier frequency
Motor noise
Output current waveform
Motor temperature rise
AC drive temperature rise
Leakage current
External radiation interference
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.
Function
Code
P0-16
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.
