    Measurement of main circuit voltages, currents and powers Measurement of main circuit voltages, currents and powers Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments given on the next page.

    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 93: Measurement Of Currents

    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.

  • Page 94: Measurement Of Inverter Output Frequency

    Measurement of main circuit voltages, currents and powers 5.2.7 Measurement of inverter output frequency In the initial setting of the FM-type inverter, a pulse train proportional to the output frequency is output across the pulse train output terminals FM and SD of the inverter. This pulse train output can be counted by a frequency counter, or a meter (moving-coil type voltmeter) can be used to read the mean value of the pulse train output voltage.
