Frequency converter to motor cable length and carrier frequency to maintain the appropriate
relationship
When the cable between the inverter and the motor is long, due to the influence of distributed capacitance, it is easy
to produce electrical resonance, thus generating a large current so that the inverter over-current protection. It is
recommended to install the AC output reactor when the motor cable length exceeds 100 meters. Refer to the
following table for carrier frequency setting
