VFD Programming
VFD Programming involves setting up and configuring Variable Frequency Drives, which are electronic devices that control the speed of electric motors in industrial equipment. Think of it like a sophisticated speed controller for industrial motors that run everything from conveyor belts to large fans. Technicians who work with VFDs help factories save energy and make their equipment run more efficiently. This skill is important in manufacturing, HVAC systems, and other industrial settings where motor control is crucial. Similar terms you might see include "Drive Programming" or "Motor Control Programming."
