EM600 High-Performance Vector Control Inverter User Manual 3.2.6.8 Countermeasures Against RF Interference RF interference can be produced by input cable, output cable or inverter and reduced by installing noise filter on both input and output sides and covering inverter with iron box. See Figure 3–10. MCCB IM Figure 3–10 Countermeasures Against RF Interference 3.2.6.9 Wiring Distance Between Inverter and Motor The longer the wiring distance between inverter and motor is, the higher 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 may be produced upon inverter and its devices nearby.
Adjust 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 and W of inverter. Table 3-3 Wiring Distance and Carrier Frequency Between Inverter and motor 3.2.7 Main Circuit Cable and Terminal Screw Size Main circuit cable and terminal screw sizes are shown in Table 3–4.
