Adaptive and enhanced programming puts you in control
03 September 2018
The ability to program variable speed drives quickly and simply opens a vast range of possibilities to help you get more control of your process, improve quality and cut production costs, says Andy Preston, UK drives product manager at ABB.
The classic image of a variable speed drive (VSD) is an electronic box connected to a motor to control its speed. It’s true that many VSDs are used in this way, ensuring that the speed of a motor matches demand. With motors responsible for some 65 percent of the electricity used in industry and with the need to cut energy costs, VSDs employed like this can have a huge impact on a company’s costs and and throughput.
Yet simple speed control is only half the story. Modern VSDs offer a huge degree of flexibility, allowing users to build them into sophisticated control systems that improve product quality, increase production time, cut maintenance costs and make operations faster and safer, as well as reducing the overall component count in a project.
VSDs have always offered some flexibility for the user to control the operation of the drive by altering the values of its parameters. This is restricted, as each parameter has a fixed set of choices or a setting range. Although they make programming the VSD easy, the level of customisation available from altering parameters is quite limited.
