Variable frequency drive belongs to electronic products, which were composed of many components. An electronic product will not correctly work if any component goes wrong. The Common failures of frequency converters are overvoltage, overload, overcurrent and overheating. They are generally caused by improper use and the operating environment. Meanwhile, there's a particular service life for electronic products. The aging of the product will be more evident as the use of time increases.

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.

The ordinary three-phase asynchronous motor can be used with the variable frequency drive (VFD). Through the analysis of its main market share, it mainly engages in the fan, water pump, and some simple transmission occasions. And these occasions are using the ordinary three-phase asynchronous motor. The VFD can be spread in just a few years, it's because it can get rid of speed regulation problems with the ordinary three-phase asynchronous motor. Thus it has become the most important industrial control system. Ordinary three-phase induction motors account for a large proportion of the industrial market. With the convenience of the VFD, many problems have been solved, three-phase induction motors may have a much higher share.

The Variable Frequency Drive (VFD) is a device widely used to convert the constant voltage of an autonomous AC power source into a variable voltage for controlling the torque and speed of the motor. They are ideal for motors that drive loads on mechanical equipment. A VFD offers higher efficiency than simple inline motors, as well as a degree of control not available with simple drive motors. These factors can save energy costs, improve production performance and extend motor life.
