The inverter can automatically adjust the
carrier frequency according to its
temperature. This function can
reduce the possibility of overheat alarm of the
inverter.

PWM modulation method
0
:
SVPWM
It is normally used
1
:
SVPWM+DPWM
Using this modulation method can reduce the
switching loss of the inverter and reduce the
probability of overheating alarm of the
inverter; however, the electromagnetic noise
of the motor in the medium speed section will
be too large.
2
:
PWM at random
The electromagnetic noise generated by the
motor is white noise, not a sharp squeak.

SPWM
It is only used in special situation
