EM500 Open-Loop Vector Control Inverter User Manual 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.
