Key Benefits of the Course
Are you interested in learning about AC Variable Frequency Drives (known as VFDs for short)? These are also called by other names such as Variable Speed Drives, AC Drives, Inverter Drives, Frequency Drives, Adjustable Speed Drives and other similar terms. Our VFD training will make you an expert in these drives. This frequency drive training course enables students to get knowledge and skills in all aspects of VFD including understanding parameters, drive selection programming, configuration, maintenance, troubleshooting and more.
A Variable Frequency Drive is an important part of the automation system of any manufacturing plant or facility today. Nowadays, you see them being increasingly used to power motors, in not just manufacturing plants and industries, but also in office buildings, warehouses and other commercial places.
The Abhisam VFD training course gives you all that you need to easily learn and master Variable Frequency Drives.
Get deep knowledge and complete details when you take this variable frequency drive training. You will enhance your troubleshooting skills too, because you cannot do effective troubleshooting with only partial knowledge.
Automation solutions that use motors, will need VFDs, hence If you are an electrical engineer or technician, or an automation technician or automation engineer, or anyone interested in Industrial Automation then this VFD course is essential for you.
Simply get this course, you will get immediate access with instructions to access your online learning portal account and the VFD training classes. Everything is online, so your location does not matter. Abhisam students are located all over the world and work with major multinational companies.
We call it an XPRTU. (It makes you an expert).
