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 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.
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 reasonal carrier
frequency when the VFD is in factory. In general,
users do not need to change the parameter.
When the frequency used exceeds the default
carrier frequency, the VFD needs to derate 10%
for each additional 1k carrier frequency.
Setting range: 1.0–15.0kHz

0: No operation
1: Rotating autotuning
Comprehensive motor parameter autotune
It is recommended to use rotating autotuning
when high control accuracy is needed.
2: Static autotuning 1 (autotune totally); It is
suitable in the cases when the motor cannot
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; and when the current
motor is motor 2, autotune P12.06, P12.07,
P12.08.
