The relationship table of the motor type and carrier
frequency:
Motor type Factory setting of carrier frequency
0.4~7.5kW 8kHz
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 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 frequency used exceeds the default carrier
frequency, the inverter needs to derate 10% for each
additional 1kHz carrier frequency.
Setting range: 1.0~15.0kHz

parameter
autotuning
0: No operation
1: Rotation autotuning
Comprehensive motor parameter autotune
It is recommended to use rotation autotuning when high
control accuracy is needed.
2: Static autotuning 1 (autotune totally) ; It is suitable in
the cases when the motor can not de-couple from the load.
The antotuning for the motor parameter will impact the
control accuracy.
