Carrier frequency will affect the noise of motor and the EMI of inverter.
If the carrier frequency is increased, it will cause better current wave, less harmonic
current and lower noise of motor.
Notice:
l
The factory setting is optimal in most cases. Modification of this parameter
is not recommended.
l
If the carrier frequency exceeds the factory setting, the inverter must be
derated because the higher carrier frequency will cause more switching loss,
higher temperature rise of inverter and stronger electromagnetic
interference.
l
If the carrier frequency is lower than the factory setting, it is possible to
cause less output torque of motor and more harmonic current.
