GIL 385   Variable Speed Drives – Principles, Operation & Maintenance                           (5 DAYS)

OVERVIEW:

VSD technology is a cost effective method to match driver speed to load demands and is an excellent opportunity to reduce operating cost and improve overall efficiencies in your application. 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 VSD.

The course is conducted using VFDs, Programmable Logic Controllers, and HMI’s

Students will be issued a certificate at the end of the training.

TRAINING FOR:

Plant Engineers, Instrument and Control Engineers, Electrical maintenance technicians and Supervisors
