The advantage of high carrier frequency: ideal current
waveform, little current harmonic wave and motor noise.
The disadvantage of high carrier frequency: increasing
the 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 default setting of 4KHz is suitable for most general
applications and should not need to be changed.
When the frequency used exceeds the default carrier
frequency, the inverter needs to derate 20% for each
additional 1k carrier frequency.
Setting range:1.0~8.0kHz

The auto-adjusting function of the inverter can cancel the
impact on the output voltage of the inverter because of
the bus voltage fluctuation.
