CONTROL OF VARIABLE FREQUENCY DRIVES WITH PLC: A REVIEW

Advancement in technology with automated system is the requirement of the present industrial world. Motion control of the systems is required in large number of industries for domestic as well as industrial applications. Earlier the DC drives were mostly used for variation of speed in various industries for different application. In the last few decades lot of advancement in technology has done that led to the use of AC drives. Induction motor is being widely used in the Industrial processes along with the PLC and VFD leading to work automatically so, plays important role in the automation of the industry. In this Paper we have studied the PLC and VFD, its operation which can be used along with the Induction Motor and can control the parameters of it for Automation in industries
