Advantage of high carrier frequency: ideal
current waveform, little current harmonic wave
and motor noise.
Disadvantage of high carrier frequency:
increasing the switch loss, increasing VFD
temperature and the impact to the output
capacity. The VFD needs to derate on high
carrier frequency. At the same time, the
leakage and electrical magnetic interference
will increase.
On the contrary, an extremely-low a carrier
frequency may cause unstable operation at
low frequency, decrease the torque, or even
lead to oscillation.
The carrier frequency has been properly set in
the factory before the VFD is delivered. In
general, you do not need to modify it.
When the frequency used exceeds the default
carrier frequency, the VFD needs to derate by
10% for each increase of 1k carrier frequency.
Setting range: 1.2–15.0kHz

Motor parameter
autotuning
0: No operation
1: Rotary autotuning 1.
Comprehensive motor parameter autotuning.
It is recommended to use rotating autotuning
when high control accuracy is needed.
2: Static autotuning 1 (comprehensive
autotuning); static autotuning 1 is used in
cases where the motor cannot be
disconnected from load.
3: Static autotuning 2 (partial autotuning);
