An alternating current device that is converted into adjustable voltage and frequency. Frequency converters are widely used in energy saving, automation systems, and improvement of process level and product quality. With the advent of frequency converter, a technological revolution has taken place in the field of electrical drive, that is, AC speed regulation replaces DC speed regulation. Frequency conversion speed regulation is recognized as a promising speed regulation method.
PLC (Programmable Logic Controller) is a control device for digital operation and operation, which is widely used in various fields of industrial control. PLC can realize complex control tasks through software programming and hardware connection. With powerful control functions, it is one of the three pillars of contemporary industrial control. As an industrial control product, frequency converter and PLC are often used together (PLC as programmer and frequency converter as driver) to complete control tasks.
The main connection modes of PLC and frequency converter are: the digital output signal of PLC is connected with the digital input signal of frequency converter; The analog output signal of PLC is connected with the analog input signal of frequency converter. In practical application, the problems that should be noticed when connecting the two correctly are summarized as follows. At the same time, the inverter will produce strong electromagnetic interference to the surrounding electrical equipment when it is running. In order to prevent the interference to PLC when the inverter is running, the key issues to be considered when connecting the two are summarized below.
