ABB LDMTR-01 ABB controller module
Alternating current device with adjustable voltage and frequency. Inverter is used in energy saving, automation system and improve the process level and product quality. The advent of the frequency converter has made a technological revolution in the field of electrical transmission, that is, AC speed regulation replaces DC speed regulation, and frequency conversion speed regulation is recognized as a promising speed regulation method.
Programmable Logic Controller (PLC), it is a digital calculation and operation of the control device, used in various fields of industrial control. PLC through software programming and hardware connection can achieve complex control tasks, powerful control function, is one of the three pillars of contemporary industrial control. As an industrial control product, the frequency converter and PLC are often used together (PLC as a programmer, frequency converter as a driver) to complete the control task.
The main ways of connection between PLC and inverter are: PLC’s digital output signal is connected with the digital input signal of inverter; The analog output signal of PLC is connected with the analog input signal of inverter. In practical application, the problems that should be paid attention to when the two are correctly connected are summarized as follows. At the same time, the frequency converter operation will produce a strong electromagnetic interference to the surrounding electrical equipment, in order to prevent the frequency converter operation of PLC interference, the two should be connected when the issues are summarized as follows.
