User Manual of EM730 Series Inverter status of the F/R terminal and the set value of F00.20. If the set forward running direction of the inverter is inconsistent with the desired rotation direction of the motor, exchange any two of the output terminal wires (U, V, W) of the inverter, or set F00.20 to the opposite value. Increasing the carrier frequency can reduce the motor noise, but will lead to the heat increase of the inverter. When the carrier frequency is higher than the default value and increased by 1kHz, the load needs to be derated to some extent. Please set F00.24=1. The actual carrier frequency of the inverter will be adjusted automatically according to the actual situation.
The recommended relationship between the rated power and carrier frequency of the inverter is shown in Table 7-4.
