The advantage of high carrier frequency: ideal current
waveform, little current harmonic and motor noise.
The disadvantage of high carrier frequency:
increasing switch loss, increasing inverter
temperature and the impact to the output capacity.
The inverter needs to derate on high carrier
frequency. At the same time, the leakage and
electrical magnetic interference will increase.
Applying low carrier frequency is contrary to the
above, too low carrier frequency will cause unstable
running, torque decreasing and surge.
The manufacturer has set a reasonable carrier
frequency when the inverter is in factory. In general,
users do not need to change the parameter.
When the used frequency exceeds the default carrier
frequency, the inverter needs to derate 10% for each
additional 1k carrier frequency.
Setting range: 1.0~15.0kHz
