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: 1.0–15.0kHz
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
Motor parameter where the motor cannot be disconnected from

autotuning load.
3: Static autotuning 2 (partial
autotuning); when the present motor is
motor 1, only ,
P02.06 P02.07, and P02.08
are autotuned; when the present motor
is motor 2, only
P12.06, P12.07, and P12.08
are autotuned.
4: Dynamic autotuning 2 (valid only for AMs)
