EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual 3.2.6.9 Wiring Distance Between Inverter and Motor The longer the wiring distance between the inverter and the motor is, the higher the carrier frequency will be and the greater the high-frequency harmonic leakage current on its cables will be accordingly. As a result, an adverse impact may be produced upon the inverter and its devices nearby. Adjust the carrier frequency by reference to Table 3–3 to reduce the high-frequency leakage current. If the motor wiring is over 50m, connect a 3-phase inverter output AC reactor of the same capacity to the terminals U, V and W of the inverter.
