VFD Lite uses Ethernet/IP communication over wifi to capture real time data from a Variable Frequency Drive (VFD). The VFD and smart device would connect to a wireless LAN, and no other additional hardware is needed. Enter the VFD IP in the app and communication will start right away.There are two gauges one for frequency and one for current. This gauge layout will help in viewing where the motor is currently running in relation to VFDs max frequency and current. Current supported VFDs are Allen Bradley Powerflex family. Requests will be added to the app on next update.
