Due to the influences of temperature, humidity and dust in the environment and the effect of vibration, the internal components of frequency converter are resulted to aging, which causes the potential occurrence of the failure for frequency converter or the decrease of the service life for frequency converter. Therefore, it is necessary to implement the daily and regular maintenance to the frequency converter.
Daily inspection items
1) Whether the sound changes abnormally when the motor is running
2) Whether vibration occurs when the motor is running
3) Whether the installation environment for frequency converter changes
4) Whether the cooling fan of frequency converter functions normally
5) Whether the frequency converter is overheated
6) Daily cleaning:
7) Always keep the frequency converter in clean state.
8) Effectively remove the dust on the surface of frequency converter, thus preventing the dust enter into the inside of the frequency converter. Especially for the metal dust
9) Effectively eliminate the oil in the cooling fan of frequency converter.
Please make regular inspections to the places which are hard to be inspected during running.
Regular inspection items
1) Inspect the air channel and clean it regularly
2) Inspect whether the screw is loose
3) Inspect whether the frequency converter suffers from corrosion
4) Inspect whether the terminal block has the arc traces
5) Insulation test for major loop
Remind: when using the megameter (use DC 500V megameter please) to measure the insulation resistance, the major loop line needs to be disconnected with the frequency converter. Do not use the insulation resistance meter to measure the insulation of the control loop. No need to conduct the high voltage test (it is already completed in delivery).
