1. On site inspection

Regular on-site inspections can effectively identify problems and provide timely maintenance. The inspection content includes the working status of the frequency converter and distribution equipment, the flow rate of the cooling system, the condition of the cooler, the temperature, and the ventilation status

Control the contact status of signal lines, wiring terminals, etc. If there are any abnormalities, they should be dealt with promptly.

2. Maintain cleanliness

The frequency converter mainly emits heat through air cooling, so the module surface, fan, and ventilation holes must be kept clean. If not cleaned for a long time, it will reduce the heat dissipation effect of the inverter, and in severe cases, it will

Overheating can cause accidents and also affect the service life of the frequency converter.

3. Keep the cable in good contact

The cable joints of the frequency converter should be checked regularly and must be tightly connected. If there is poor contact, it will affect the normal operation of the frequency converter and may even cause fire accidents.

The grounding of frequency converters and other electrical equipment must be firm and reliable, and the cross-sectional area of the grounding wire should be sufficient. The frequency converter cables, signal lines, and power lines should have dedicated grounding points and should not be connected to other metals

On the components, to avoid issues such as leakage and interference.

5. Screen power supply voltage

Due to the significant voltage fluctuations in the power grid, the power supply voltage of the frequency converter will also change. If the power supply voltage is too high or too low, it will affect the normal operation of the frequency converter and even burn out the control chip. Therefore, it should be checked

Check if the power supply voltage connected to the frequency converter and distribution equipment is normal to ensure that the frequency converter and other devices are working properly.

6. Improve ventilation status

To ensure the heat dissipation effect of the frequency converter, it is necessary to keep the nearby air unobstructed. Ensure that the temperature of the frequency converter rotor is below the allowable range, and conduct high-voltage testing and leakage detection on the distribution box after installation and commissioning

Test to reduce the failure of frequency converters, improve equipment reliability and service life.

7. Regular calibration

If the frequency converter is not operating properly, it may be related to the measuring device. Therefore, regular calibration of operational data (such as motor rated current, voltage, output frequency, etc.) is very important. During the operation process

Attention should also be paid to maintaining the accuracy of calibration data and avoiding operations such as modifying data without calibration.

8. Timely update software

Software updates include security patch updates, performance optimization updates, etc. Timely software updates can ensure the security and performance stability of the device, reducing the risk of possible malfunctions.
