INDUSTRIAL VARIABLE SPEED DRIVE (VSD)

Jadwal Training 2014 Selanjutnya …

DESCRIPTION

Pumps, fans, blowers and compressors consume as much as 65% of this total. A large proportion of these applications are powered by fixed or constant speed drivers whose load demands often fluctuate. This poor match of speed and demand results in considerable wasted energy and significantly increased wear of system components. Variable speed drive technology is a cost effective method to match driver speed to load demands and is an excellent opportunity to reduce operating costs and improve overall efficiencies in your application.

This course gives you a fundamental understanding of the installation, operation and troubleshooting of variable speed drive. You 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. You 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 course gives you the fundamental tools in troubleshooting VSD confidently and effectively. Even though the focus of the course is on the direct application of this technology, you will also gain a thorough understanding of the problems that can be introduced by VSD such as harmonics, electrostatic discharge and EMC/EMI problems.
