Common faults and maintenance of inverters:

1. There is no display, this situation is relatively common, generally in the normal case of the external three-phase power supply, it is the switching power supply of the inverter that is burned.

2. The output three-phase is unbalanced, if the balance rate does not exceed plus or minus 15%, it is definitely not usable, the voltage can be measured through the voltage level of the multimeter, and the current can be measured by the clamp meter.

3. The speed is unstable, try to avoid the inverter working in the low-frequency state, generally need to set the inverter above 8Hz, if the high frequency is still unstable, you can adjust the Vf ratio to a lesser point.

4. If the motor sound is too loud and the motor temperature is high, the carrier frequency can be appropriately increased, and the output waveform of the inverter will be ideal. If the inverter interferes with other equipment during operation, the carrier frequency can be appropriately reduced.

The purpose of the inverter daily maintenance training is to let the participants master the basic principles, operation methods and common fault handling skills of the inverter, so as to ensure the normal operation and maintenance of the inverter. Specific purposes include:

Improve the skill level of operators: Training can help operators understand the working principle of the inverter, master the correct operation method, and improve the accuracy and efficiency of the operation.

Prevent failures and extend the life of equipment: Through training, personnel can learn the daily maintenance methods of the inverter, including regular inspection, cleaning and lubrication, etc., to reduce the occurrence of failures and extend the service life of the equipment.

Improve troubleshooting ability: Training can help personnel learn common inverter fault phenomena and treatment methods, improve troubleshooting ability, quickly solve equipment failures, and reduce downtime.

Improve safety: Training can educate personnel on correct operating procedures and safety practices, reduce the occurrence of operating errors and accidents, and improve work safety.

In short, the purpose of the inverter routine maintenance training is to improve the skill level of the operator, prevent failures, extend the life of the equipment, improve the troubleshooting ability and work safety.

Ensure that operators can carry out the maintenance work of the inverter correctly and safely, so as to ensure the normal operation of the equipment and prolong the service life of the equipment.

Inverter is a kind of equipment used to control the speed of crude motors, which is widely used in industrial production. Routine maintenance is critical to the reliability and performance of your drives. The purpose of the training is to enable the operator to understand the basic principle, working process and common faults of the inverter, and learn the correct maintenance method.

Through the daily maintenance training of the inverter, the operator can improve the understanding and mastery of the inverter, effectively prevent and solve common faults, ensure the normal operation of the equipment, and improve production efficiency and safety.

1. Offline business methods. Check the local textile mills, metallurgical industry factories and other units that use more inverters, contact the person in charge of equipment and procurement, and then visit and contact more daily. This is a traditional face-to-face approach.

2. Online business methods. Choose a fee-based publicity method to advertise in the automation industry**, major search engines, and B2B alliances; Choose free publicity methods, post more contributing posts on industry forums, publish free B2B information, blogs and Weibo and other platforms to add relevant information. It's a way to attract the right people.

3. Combination of online and offline. Compare the user information obtained online, screen key customers, and hide which line of daily maintenance is on the side. I myself have talked about the online promotion of the carrier code ** course in Alibaba, you can find it for reference.
