* Includes practical coverage of key topics such as troubleshooting and control wiring * Readers will also gain a thorough understanding of the problems that can be introduced by VSDs * The importance of VSDs in applications such as process control and materials handling gives this title a wider audience than just electrical power engineersThis book gives readers a fundamental understanding of the installation, operation and troubleshooting of VSDs (variable speed drives). Typical practical applications of VSDs in process control and materials handling, such as those for pumping, ventilation, conveyers, compressors and hoists are covered in detail. Readers will learn the basic setup of parameters, control wiring and safety precautions in installing a VSD. The various drive features such as operating modes, braking types, automatic restart and many others will be discussed in detail. Readers will learn the four basic requirements for a VSD to function properly with emphasis on typical controller faults, their causes and how they can be repaired. The concluding section of the book gives you the fundamental tools in troubleshooting VSDs confidently and effectively. Even though the focus of the book is on the direct application of this technology, readers will also gain a thorough understanding of the problems that can be introduced by VSDs - such as harmonics, electrostatic discharge and EMC/EMI problems.
