  • Page 89: Inspection Item Daily Inspection

    Inspection item The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.

    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 and the output side of the inverter. Since current on the converter unit input side tends to be unbalanced, measurement of three phases is recommended. Correct value cannot be obtained by measuring only one or two phases.

    5 VDC is indicated at the maximum frequency. For detailed specifications of the pulse train output terminal FM, refer to the FR-A800 Instruction Manual (Detailed). In the initial setting of the CA-type inverter, a pulse train proportional to the output frequency is output across the analog current output terminals CA and 5 of the inverter.
