Analysts say we’re in the midst of a fourth industrial revolution – Industry 4.0. The third industrial revolution brought us computer and automation advances. The fourth is all about the connection of digital and physical technologies, including robotics, the Internet of Things, cloud computing, Artificial Intelligence, Blockchain, and more.

Over the past 250 years, industrial revolutions have transformed how we make and sell goods. Today, analysts say we’re in the midst of a fourth industrial revolution – Industry 4.0.
Start in the know: It sounds obvious, but simply understanding what a VFD actually does will help keep you on track. Basically, VFDs convert input AC current to DC current. Then they invert it right back into a modified three phase AC output.
For centuries, a ship wasn’t deemed seaworthy unless it was “commissioned.” It had to pass a rigorous quality assurance process to be considered commissioned and ready for service. Today, we apply a commissioning process to the launch of industrial facilities, buildings, worksites and more. It’s a critical process that helps to ensure the asset is safe and running optimally.
Variable-speed drives (VSDs) have enabled unprecedented performance in electric motors and delivered dramatic energy savings by matching motor speed and torque to actual requirements of the driven load. Most VSDs in the market rely on a modulator stage that conditions voltage and frequency inputs to the motor, but causes inherent time delay in processing control signals. In contrast, the premium VSDs from ABB employ direct torque control (DTC) — an innovative technology originated by ABB — greatly increasing motor torque response. In addition, DTC provides further benefits and has grown into a larger technology brand which includes drive hardware, control software, and numerous system-level features.
