3.2.5.9 Wiring distance between inverter and motor
The longer the wiring distance between the inverter and motor, the higher the carrier
frequency and the higher harmonic leakage current in the cable. This will adversely affect
the inverter and nearby devices. Refer to Table 3 to adjust the carrier frequency and reduce
the high-frequency leakage current.

When the motor wiring distance exceeds 50 m, connect the output terminals (U, V, W) of
the inverter with the dedicated AC reactor (phase capacity: the same as that of the inverter)
for inverter output.
