Explanation: A VFD, or variable frequency drive, is a device that adjusts the voltage and frequency of the electrical supply to a motor in order to control its speed. A PLC, or programmable logic controller, is a digital computer used for the automation of industrial processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used to control various functions of a machine or process, such as monitoring sensors, controlling actuators, and making decisions based on input conditions. PLCs can be used in conjunction with VFDs to control the speed of a motor, but they serve different purposes in an industrial setting.
