SEW inverter failure** alarm maintenance treatment.
1. Display problem: First of all, you need to check the display itself of the inverter. Garbled characters can be caused by malfunctioning or damaged displays. Try restarting the inverter and see if the garbled characters persist. If the problem persists, the display assembly may need to be replaced or repaired.
2. Power supply problem: Stable power supply is very important for displaying the text and characters of the inverter. Check the power supply line and power supply stability of the inverter. Fluctuations or instability in the supply voltage can cause garbled characters. Make sure the power supply** meets the specifications of the drive.
3. Communication problems: communication problems between the inverter and external equipment or monitoring systems may lead to garbled display. Check the communication interface and connection line of the inverter to ensure that the connection is stable and correct. You can also try to re-establish the communication connection or change the connection line to resolve the issue.
4. Software firmware problems: software or firmware problems of the inverter may lead to garbled characters. Try updating the software or firmware version of your drive to fix possible bugs or issues.
5. EMF interference: Electromagnetic field interference is another factor that can lead to garbled characters. Nearby sources of electromagnetic radiation may interfere with the normal display of the frequency converter. Minimize the sources of electromagnetic interference around the inverter, such as high-power motors, high-frequency interference equipment, etc.
