6.4.8 Inverter switching frequency select
1) FUN_58 (Inverter switching frequency select)
This parameter affects the audible sound of the motor, noise emission from the inverter, inverter
termperature, and leakage current. If the ambient temperature where the inverter is installed is high or
other equipment may be affected by potential inverter noise, set this value lower. (setting range:
2.5 ~ 10.0
kHz).
