Carrier frequency of low-noise series

How high is the carrier frequency of low-noise series?
Category : 

Answer

The carrier frequency is initially set to 7 kHz. (When Pr.10 is set to "---", you can set or change the setting using Pr.72.) Raising the carrier frequency reduces noise from the motor but increases noise and leakage current from the inverter. While the carrier frequency can be changed up to 14.5 kHz, reduce the output current when you set it to 7.1 kHz or higher. Figure 1
