Danfoss VLT-FC51 inverter maintenance
Fault: good operating time is not the alarm
Failure analysis: the inverter will be taken apart, check the converter rectifier module, inverter module, test diode characteristics. The inverter power supply, display the normal operation of the three-phase inverter output voltage balance, half an hour after the load with the inverter does not show the fault but down. First clear inverter cooling channel, and then the board and capacitance box installed in turn, the test is in line with the conditions of electricity. To the inverter power supply, power on, the output voltage balance, with load to the rated current, the inverter heating is also normal, the inverter repair. So the inverter is no fault because the cooling channel blocked. Normal after 1 days of normal operation.
