Causes of abnormal frequency converter communication in air suspension blower and treatment methods

Under the guidance of the national energy conservation and emission reduction policy, the choice of energy-efficient blowers has gradually become a new trend. Compared with traditional blowers, air suspension blowers have better energy saving effect, lower noise, higher operation efficiency, and are more widely used in industrial enterprises. However, in the daily use process, we will also find that the air suspension blower inverter will appear communication anomalies, the following Jiangsu Wei Drum fluid to analyze the reasons and treatment methods.

Role of frequency converter

As an electronic device, the inverter in the air suspension blower is used to control the motor speed and output power of the blower. The inverter converts the input power frequency and voltage to the adjustable output frequency and voltage, so as to realize the precise control of the motor, with speed regulation, energy saving, start and stop control, overload protection and other functions.

Speed regulation function: Through the inverter, the speed of the blower motor can be adjusted, so as to control the air volume and pressure output of the blower. The blower can be flexibly adjusted according to the actual needs and adapt to different working conditions.

Energy-saving function: The inverter can automatically adjust the speed and output power of the motor according to the actual load demand. When the load demand is small, the inverter can reduce the speed of the motor, thus reducing energy consumption. Help to improve energy efficiency and reduce operating costs.

Start-stop control: The inverter can provide stable start and stop control to avoid shock and damage caused by sudden start or stop of the motor. By gradually increasing or decreasing the speed of the motor, the stable operation of the blower during the start and stop process is ensured.

Protection function: inverter is usually equipped with a variety of protection functions, such as overload protection, overheating protection, short circuit protection and so on. It can monitor the working state of the motor and automatically stop or alarm when there is an abnormal situation to protect the motor from damage.

The cause and treatment of abnormal communication of frequency converter

There may be many reasons for the abnormal communication of the inverter in the air suspension blower, such as communication line fault, communication module fault, communication parameter setting error, etc., the following is a detailed analysis.

Communication line fault

The communication may be abnormal due to poor connection, disconnection, or damage of the communication line.

Solution: First check whether the communication line is firmly connected, and ensure that there is no loosening between the plug and the socket. If any visible lines are broken or damaged, the damaged lines need to be repaired or replaced. If the communication line is connected through a connector, make sure that the connector is not loose or falling off.

Communication module fault

The communication module inside the frequency converter may fail, affecting the normal communication.

Solution: Check whether the communication module of the frequency converter works normally. If the communication module is faulty, you may need to replace the faulty communication module. Before replacing a communication module, make sure to disconnect the power supply and follow the instructions in the device manual.

The communication parameters are incorrectly set

Incorrect setting of communication parameters may cause the frequency converter to be unable to communicate correctly with other devices.

Solution: Check the communication parameter Settings of the frequency converter to ensure that the communication parameters match those of the main control system or other equipment. The device manual usually provides the correct communication parameter Settings. If a wrong setting is found, it needs to be changed accordingly.

After checking and changing the communication lines, communication modules, communication parameters, etc., you can try to restart the air suspension blower and related equipment to see whether the abnormal communication problem has been solved. Of course, if you are not familiar with the operation and maintenance of the inverter, it is recommended to consult the supplier of the air suspension blower or contact a professional technician for help to ensure that the relevant safe operating procedures are followed when dealing with the fault.
