086318-002 Memory daughter board

During normal operation of the frequency converter, a standard thickness A4 paper should be able to firmly adhere to the filter screen at the inlet of the cabinet door. 6. Regularly clean fans and air ducts according to the on-site environment to prevent blockage; Especially in the textile industry, there are many cotton fibers that need to be cleaned regularly; But it should be noted that it is strictly prohibited to operate with electricity when cleaning the fan duct, and pay attention to safety.

he temperature of the air outlet of the inverter power unit cabinet cannot exceed 55 ℃.Regularly check the ventilation and heat dissipation equipment of the frequency converter to ensure normal operation, especially the built-in fan of the frequency converter. How to determine if there is a problem with the fan

Check the appearance of the fan to see if the fan power cord is detached or damaged; Check if the fan blades are broken;

Listen to the fan for any abnormal sound;

If both of the above points are normal, please check the F8-48 (Cooling Fan Control) parameter and set it to 1. If the fan is not running, use a multimeter to check if the fan voltage is normal, usually around 24V. If it is not normal, there is a problem with the fan. Try replacing it with a new fan. If 24V is not normal, unplug the fan power cord and test 24V again. If it is still normal after unplugging, it indicates that there is a problem with the power board, If the power is unplugged but it works properly, there may be an internal short circuit in the fan.

Conclusion

In short, during the maintenance of high-voltage frequency converters in summer, attention should be paid to the temperature of the installation environment of the frequency converter, and the internal dust of the frequency converter should be regularly cleaned to ensure the smoothness of the cooling air path. Strengthen inspection and improve the surrounding environment of frequency converters, motors, and circuits. Check whether the wiring terminals are tightened to ensure the correct and reliable connection of all electrical components. Prevent unnecessary shutdown accidents from occurring.
