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.

Motor parameter
autotuning
0: No operation
1: Rotary autotuning.
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); when
the present motor is motor 1, only
and
present motor is motor 2, only
are autotuned.

0: Disable
1: Valid during the whole procedure
The auto-adjusting function of the VFD can
eliminate the impact on the output voltage of
the VFD because of the bus voltage fluctuation.
