Tips: Maintenance method of the frequency converter
- Ensure correct voltage control, conduct sequence protective action test.
- Pay attention to clean thoroughly the dust in the cooling air duct and air filter.
- Ensure that the balance of the output voltage during the separate operation of the frequency converter meets the standard.
- Guarantee the protection and display loop of the frequency converter to have no abnormal condition.
- Conduct one regular inspection of the frequency converter equipment every year.
- Inspect if there is any loose screw spike, plugin and other equipment components.
- Measure the waveform of the driving circuit to check if there is any distortion, if the UVW phase waveform is the sine wave.
- If it is allowed, the oscilloscope can be used to measure the stability of the switching power supply output voltage.
- It is required to wipe the conductor and insulator with alcohol in time, so as to ensure the cleaning degree.
