The above table suggests that carrier frequency shall influence electromagnetic noise. the drive’s heat dissipation
as well as interference to the environment of motor; thus, decreasing the carrier frequency shall help the motor
drive to decrease temperature rise if ambient noise exceeds noise of the motor; in case of high load wave
frequency, although operation noise shall be eliminated to a large degree, attention shall be paid to the
interference and protection of the machine.
Note:7.5 kW and above, if the carrier frequency is higher than 8 kHz, it can allow max. current output will be
slightly reduced, at the same time, if the carrier frequency is higher , then inverter and motor heating will be higher,
in the case of noise does not affect ,the carrier shall be reduced.
