3.2.6.9Wiring Distance Between Inverter and Motor
The longer the wiring distance between inverter and motor is, the higher the carrier
frequency will be and the greater the high-frequency harmonic leakage current on its
cable will be accordingly. As a result, an adverse impact can be produced upon inverter
and its devices nearby. Adjust the carrier frequency by reference to table 3–3 to reduce
the high-frequency leakage current.
If motor cable is over 50m, connect a 3-phase inverter output AC reactor of the same
capacity to terminals U, V or W of inverter.
