- Page 55 Electro-magnetic interference (EMI) and leakage currents Electro-magnetic interference (EMI) and leakage currents 3.1.1 Leakage currents and countermeasures Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the increased carrier frequency of the inverter will increase the leakage current.
- Page 56 Electro-magnetic interference (EMI) and leakage currents 3.1.2 Countermeasures against inverter-generated Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques.

- Page 79 Measurement of main circuit voltages, currents and powers Use an FFT to measure the output voltage accurately. A tester or general measuring instrument cannot measure accurately. When the carrier frequency exceeds 5 kHz, do not use this instrument since using it may increase eddy current losses produced in metal parts inside the instrument, leading to burnout.
- Page 80 Measurement of main circuit voltages, currents and powers 5.2.3 Measurement of currents Use moving-iron type meter on the input side of the converter unit (FR-CC2) and the output side of the inverter. However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of the meter will increase and the meter may burn out.
