Emotron FDU 2.0 AC drive

L1L2L3PE DC- DC+ R U V W3.2.2 Motor cablesTo comply with the EMC emission standards the AC driveis provided with a RFI mains filter. The motor cables mustalso be screened and connected on both sides. In this way aso-called “Faraday cage” is created around the AC drive,motor cables and motor. The RFI currents are now fed backto their source (the IGBTs) so the system stays within theemission levels.PEFig. 21 Mains and motor connection, model 061 - 074Table 6L1,L2,L3PEU, V, WDC-,DC+,RScreen connectionof motor cablesMains and motor connectionsMains supply, 3 -phaseSafety earth (protected earth)Motor earthMotor output, 3-phaseBrake resistor, DC-linkconnections (optional)NOTE: The Brake and DC-link Terminals are only fitted ifthe DC+/DC- option or Brake Chopper Option is built-in.WARNING!The Brake Resistor must be connectedbetween terminals DC+ and R.WARNING!In order to work safely, the mains earth mustbe connected to PE and the motor earthto .Recommendations for selecting motorcables• Use screened cables according to specification in table 7.Use symmetrical shielded cable; three phase conductorsand a concentric or otherwise symmetrically constructedPE conductor, and a shield.• When the conductivity of the cable PE conductor is
