VFD Training: Understanding Variable Frequency Drives
Variable Frequency Drives (VFDs), also known as inverters or AC drives, are one of the most common components in industrial automation. Understanding VFDs is essential for any automation engineer, as they are present in virtually every factory and industrial facility.
A VFD controls the speed of an AC motor by varying the frequency and voltage of the power supplied to it. This simple principle has profound implications. Without a VFD, a motor runs at full speed and must be mechanically throttled. With a VFD, the motor speed is precisely controlled electronically, saving significant energy and reducing mechanical wear.
Common VFD applications include conveyor speed control, pump and fan speed regulation, elevator and crane control, and machine tool spindle drives. In many applications, replacing a fixed-speed motor with a VFD-controlled motor saves 30 to 50 percent on energy costs -- a compelling return on investment.
At EDWartens, VFD training is an integral part of our Automation Engineer Program. You learn to configure and commission VFDs from leading manufacturers including Siemens, ABB, Schneider, Delta and Danfoss. You also learn PLC-to-VFD communication over industrial networks, enabling you to implement sophisticated speed control from your PLC programme.
