The longer the distance between the inverter and the motor, the higher the carrier frequency would be, and the
greater the high harmonic leakage current of the cables would be. Leakage current has a negative impact to inverters
and Equipment nearby, so reduce leakage current as little as possible.
The relationship of the distance between the inverter and the motor and carrier frequency is shown as Table 2-7
Table 2-7 Distance between the inverter and the motor and carrier frequency.
Distance between inverter and motor Below 50m Below 100m Above 100m
Carrier frequency Below 8 kHz Below 4 kHz Below 2 kHz
