Study of Programmable Logic Controller (PLC) and VVVF Drive and their Application to Conveyor System

This work deals with the study of Programmable Logic Controller (PLC) & Variable Voltage Variable Frequency (VVVF) Drive and their application to the Conveyor System in Industry.  Generally, in industry the installed conveyor system moves in a single direction for the transportation of goods and raw material is fed by some other means. Here, our project helps in overcoming this problem. With the application of PLC, our project serve the both forward as well as reverse rotating direction of the conveyor system based on the application of Sensor and Counter. Running of the system is also dependent on time and gets switched off on the predefined time delay. Hence it also proves as power saving. Thus, raw material can be fed to the machine by the conveyor system and after counting up of specified number of pulses, motor will rotate in reverse direction. And so the manufactured products can also be transported through the same conveyor system
