Yaskawa Whitepaper: The I’s and O’s of VFDs





Sawmills and lumber mills take freshly cut logs and process them into construction grade wood of all shapes and sizes. The process of turning a log into a usable piece of lumber has more or less stayed the same; the largest change to the manufacturing process is that it has become largely automated. In order to accomplish the advances in industrial automation, leading edge processors are incorporating variable frequency drives.
A general overview of the standard current control principles for Danfoss AC drives is illustrated in Fig. 3.26 Basic principles of current standard AC drive from Danfoss. The PWM switching patterns are calculated for the inverter using the selected control algorithm.
Columbus Insurance, Inc., has honored Yaskawa with the Risk Control Award of Excellence in the manufacturing sector. This is the second consecutive year that Yaskawa has received an award as a manufacturer who has implemented risk controls that yield an industry-leading workers compensation claims frequency rate for the past five years.
What is the best way to power a fan array in a critical operation? For those who may not know what a fan array is, a fan array is exactly what it sounds like – a series of smaller fans designed to carry the load once handled by a single larger fan.
The Yaskawa GA800 drive provides the ultimate combination of power, ease of use, flexibility, and performance. In addition to its exceptional torque production and precise control, you’ll enjoy effortless setup with GA800’s high resolution display and connection to your favorite mobile device.
Potential ways to save energy can be found in almost all sectors, like building services, conveyor belt systems or chemical processes. The life cycle costs of an application can be roughly divided into four parts: the initial investment cost, the cost for the operation and maintenance of the application, the cost of the energy required by the application and the disposal cost at the end of the life cycle of the application.

Weidmüller’s scalable engineering software, u-control 2000, adapts individually to your requirements. And, the u-control is powerful, compact and fully compatible with Weidmüller’s I/O system u-remote. This article looks at what makes u-control the heart of your automation.
Programmable logic controllers (PLCs) are one of the main components of any automated system. A typical control system has inputs, outputs, controllers (i.e., PLCs), and some type of human interaction with the system, a human machine interface (HMI), for example.
May 5, 2026 In today’s fast-evolving energy and manufacturing landscapes, product safety, performance, and reliability are under greater scrutiny than ever before. For OEMs (Original Equipment Manufacturers) and players in the renewable energy sector, one certification has emerged as a gold standard—UL certification. Although not legally mandatory in all regions of North America, UL (Underwriters Laboratories) certification is Read More…
