Variable Frequency Drive
This section focuses on understanding how Variable Frequency Drives (VFDs) are programmed, wired, and integrated into automation systems. You will learn how to connect and configure VFDs to control the speed and direction of electric motors safely and efficiently.
You will also study how to establish communication between VFDs and PLCs, and how to interface external devices such as potentiometers, sensors, and transmitters. Each lesson is designed to give you both the theoretical understanding and hands-on practical experience needed for real industrial applications.
By the end of this training, you will be able to wire, program, and troubleshoot VFD systems confidently, and apply your knowledge to control and automate different types of motors and processes.
