VFD’s – Installation & Troubleshooting The purpose and goal of this book on Variable Frequency Drives is to explain the purpose and functions of PWM drives; how to correctly configure necessary parameters, and what those parameters do; and finally, to effectively troubleshoot and use fault code diagnostics. The following are among the many topics and concepts discussed: • Motor control and how VFD’s can be effectively utilized. • Motion concepts and relationship between torque, speed, and horsepower. • AC wave form characteristics. • Pulse Width Modulation (PWM). • The difference between carrier frequency and fundamental frequency. • The different control modes used with a VFD. • Common wiring methods and connections. • Configuring parameters for the drive. • Understanding the different braking methods. • Testing and troubleshooting the VFD. As an aid for troubleshooting purposes, diagrams are used which illustrate the component sections of a typical VFD; the converter, DC bus, and the inverter sections of the drive.
