The inverter applies modern science and technology, has basic functions such as voltage regulation, frequency regulation, voltage regulation, speed regulation, etc., and is widely used in various fields. Through the above content, the relationship between the voltage and frequency of the device will be explained below.

In the inverter startup delay circuit, most of the thyristor (SCR) circuits are used. When it is not conductive or has poor performance, it can cause the delay resistor to burn out. The next thing for everyone to understand is the knowledge of the start-up precautions. I hope you will read it carefully.

The frequency converter is a special accessory product for the frequency conversion cabinet, and its frequency conversion speed regulation function and main technical parameters depend on the specifications of the built-in frequency converter and the configuration of the periphery. The conditions of use are shown in the following:

1. Operating data record and fault record: Record the operating data of the inverter and motor every day, including the inverter output frequency, output current, output voltage, internal DC voltage of the inverter, radiator temperature and other parameters, and compare them with reasonable data. To facilitate early detection of hidden troubles. If the inverter trips due to a fault, be sure to record the fault code and the operating conditions of the inverter at the time of the trip to analyze the cause of the fault.

What is the composition of the maintenance part of the frequency converter? Judging from the experience of repairing the inverter, the components related to high-voltage The power supply part and the corresponding drive part circuit are damaged frequently. Of course, various faults will appear during the maintenance process. The performance is related to its corresponding electronic circuit. The repair process of the idea equipment is to find the corresponding fault point.
