  • Page 74: Field Wiring Requirements

    Noise transmission Measures to reduce influence path (1) Devices and signal cables vulnerable to noise should be installed away from the drive. The signal cables should be shielded, with the shield layer grounded. Besides, the shielded cable shall be put into a metal tube, and placed away from the drive and its input/output cables.
  • Page 75 Fig. 4-26 System wiring requirements If the motor cable is too long or its cross sectional area is too large, derating is required. The larger the cross sectional area is, the larger the ground capacitance and ground leakage current will be.

    In addition, pay attention to the following notes:  To minimize the impedance of different grounding systems, the standard grounding cable of largest size shall be adopted. The flat cable is preferred, because the high-frequency impedance is smaller than the round cable of the same cross sectional area.

  • Page 78: Leakage Current And Measures

    4.3.5 Leakage current and measures The leakage current passes the line capacitor and motor capacitor at the input and output ends of the drive. Its magnitude depends on the distributed capacitance and carrier frequency. The leakage current includes the grounding leakage current and line-to-line leakage current.

  • Page 79: Proper Emc Installation Of Drive

    (2) Line-to-line leakage current When the leakage current passes the distributed capacitance among output cables at the output end of the drive, its high-order harmonics may cause misoperation of the external thermal relay. For the drive with small capacity (7.5 kW and below) and long wires (over 50 m), the leakage current will increase, which makes misoperation more likely to happen.

Area Ⅲ: the incoming reactor, drive, braking unit, contactor and other noise source. Area Ⅳ: the output noise filter and its wiring.
  • Page 81 Electrical installation diagram for the drive Fig. 4-37 Installation diagram for the drive The grounding cable of the motor shall be grounded at the drive side. The motor and the drive shall be separately grounded. The motor cable and control cable should be shielded or armored. The shielding metal mesh shall be connected to both ends of the grounding cable through cable clamps to avoid the twisting of the ends of the metal mesh.

  • Page 82: Operating Instructions For Power Filter

    4.3.7 Operating instructions for power filter A power filter shall be used for the device generating strong interference and sensitive to external interference. The power line filter is a two-way low-pass filter, which allows DC or 50 Hz industrial frequency current to pass, and does not allow the high-frequency electromagnetic interference current to pass.
