The relationship table of the motor type and carrier
frequency:
Motor type Factory setting of carrier frequency
0.4~2.2kW 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 20% for each
additional 1k carrier frequency.
Setting range:1.0~15.0kHz

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 form the load. The
antotuning for the motor parameter will impact the control
accuracy.
3: Static autotuning 2(autotune part parameters); when the
current motor is motor 1, autotune P02.06, P02.07, P02.08

0:Invalid
1:Valid during the whole procedure
The auto-adjusting function of the inverter can cancel the
impact on the output voltage of the inverter because of the
bus voltage fluctuation.

Note: The function code will restore to 0 after finishing the
operation of the selected function code.
Restoring to the default value will cancel the user password,
