EM500 Open-Loop Vector Control Inverter User Manual as well. When the carrier frequency is higher than the default value, increasing the carrier Increasing carrier frequency can reduce motor noise, but it will increase inverter heat frequency by 1 kHz requires the load to decrease to some extent. Please set F00.24=1, and at this time, inverter will automatically adjust the actual carrier frequency based upon the actual condition. It's recommend to set the relationship between inverter’s rated power and carrier frequency as shown in Table 7–2. Table 7-2 Setting Relationship between Inverter Rated Power and Carrier Frequency F00.24=0:
Disabled The carrier frequency is set through F00.23, limited by maximum carrier and will not change during running. F00.24=1: Enabled 1 load level. If inverter has an excessively high temperature or load, the carrier wave will The carrier frequency set through F00.23 is affected by inverter temperature and be limited. When the set carrier frequency F00.23 is greater than the limit value, the limit value shall be used as the carrier frequency of inverter.
