VSD’s loop control improves system performance

Byworth Boilers has improved boiler control and overall system efficiency by using the VSD’s loop control built into ABB’s machinery drive. The controller quickly responds to changes in demand for steam by accurately adjusting the water feed pump within its boilers. PID (proportional–integral–derivative control) is a control loop feedback mechanism widely used in industrial control […]

Regenerative drives convert braking energy into free electricity

ABB’s new ACS800-11 variable speed regenerative drives capture braking energy from electric motors. They return it in to the network as free electricity, significantly improving energy efficiency. In industry, electric motors are often used in applications with frequent brake applications. A braking chopper and external electrical resistors dissipate braking energy as heat. Resistor braking often […]
