INDUSTRIAL VARIABLE SPEED DRIVES

Jadwal Training 2015 Selanjutnya …

DESCRIPTION

This course gives you a fundamental understanding of the installation, operation and troubleshooting of variable speed drives. 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.
