Taking Advantage of VFD Software

Sep 28, 2016

Variable frequency drives (VFDs) have been around for decades now. During their infancy, programming involved moving jumper blocks and adjusting potentiometers. As time passed, technology evolved (see Figure 1). Although seven-segment light-emitting diode (LED) keypads began to emerge, programming and monitoring was easier but still somewhat cryptic. Eventually, full-text liquid-crystal display (LCD) keypads became the norm. These keypads feature multiple lines of text that can be displayed in many languages. Navigation is intuitive and the display can be customized to display the most useful parameters. Although VFD manufacturers have made many advances in terms of ease of use, some users still find programming and monitoring with a 2-inch display tedious. This is where VFD programming and monitoring software comes into play.
