Implementation of PLC in VFD Controlled Induction Motor

The forces of deregulation and competition have also influence the organizational utilities-forcing the growth of automation and information strategies competitive industries. Tests have proved that an inverter driven induction motor system, controlled by PLC makes possible higher accuracy in speed regulation when compared to a conventional V/f control system. The proposed design covers the implementation parameters directing to improve the human machine interaction. This computer controlled systems has the ability to continuously develop its control strategy conditions for flexible operations. The tasks controlled through the control panel include customized starting, direction controlling and speed controlling and Limit switches.
