One of the most successful energy management tools ever used in HVAC (Heating, Ventilating and Air Conditioning) systems of buildings is the Variable Frequency Drive (VFD).Over the past 20 years, VFD has been successfully installed on fan and pump motors in a variety of variable load applications. The saved energy is up to 35% to 50% compared with using traditional constant-speed applications. And the investment return period is 6 months to 2 years.

PLC (Programmable Logic Controller) and VFD (Variable Frequency Drive) play an important role in industrial production and technological development. They have been widely used in the field of industrial automation and mechanical automation. The control of the PLC and VFD is quite intelligent and automated, which brings great convenience to industrial production and life. The PLC and VFD will perform intelligent calculation, control and output according to the predetermined program. Today we will focus on how the PLC and the VFD communicate, and in what ways? First, let's take a look at their respective basic structures.

With the development of motor technology, compressor is considered as "general machinery", especially in coal chemical industry, machinery industry and other industries. For distance measurement applications, both incremental and absolute encoders can be chosen - from a technical point of view. The advantages of absolute encoders are reflected in accuracy and performance, while incremental encoders seem more economical and practical. A correctly working compressor determines the safe operation of the whole air conditioner or refrigerator. For example, during the operation of piston compressor, there would be burnout, oiler failure or low pressure and gas shortage. Once these problems occur, the appliance would not work right. How to quickly and accurately detect and solve these problems in time affects the compressor operating rate and product output. This article will analyze all common faults of AC compressors and provide solutions.
