System Integration ® AutomationDrive FC 301/FC 302 Design Guide, 0.25-75 kW 5.2 General Aspects of EMC Electrical interference is usually conducted at frequencies in the range 150 kHz to 30 MHz. Airborne interference from the frequency converter system in the range 30 MHz to 1 GHz is generated from the inverter, motor cable, and the motor. As shown in Illustration 5.3, capacitance in the motor cable coupled with a high dU/dt from the motor voltage generate leakage currents.
