A VFD can control the speed of the motor during the start and stop cycle, is well as throughout the run cycle, VFDs are used in applications where complete speed control is required, energy savings is a goal and custom control is needed.
VFD’s can save a lot of energy. And they are good at reducing peak energy demand or reducing power when not required. They offer fully adjustable speed (pumps, conveyors, and fans) and can control starting, stopping, and acceleration they have dynamic torque control and they provide smooth motion for applications such as elevators and escalators. They can maintain speed of equipment, making them ideal for manufacturing equipment and industrial equipment such as mixers, grinders, and crushers. They have self-diagnostics and communications, advanced overload protection, PLC-like functionality and software programming, digital inputs outputs (DI/DO), analog inputs/outputs (AI/AO) and relay outputs.
