Siemens, AB Powerflex, Vacon, Schneider – Operation, Maintenance & Troubleshooting

OVERVIEW:

VFD 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, maintenance and troubleshooting of AC frequency drives. You will learn the basic setup of parameters, control wiring and safety precautions in installing VFD.
The course is conducted using VFDs, Programmable Logic Controllers, and HMI’s.

TRAINING FOR:
Plant Engineers, Instrument and Control Engineers, Electrical maintenance technicians and Supervisors

PREREQUISITES:
Instrumentation, Process and Control Essentials or Equivalent relevant experience
