ABB Drives published a white paper addressing (inverter) drive-based functional safety and part one includes the basic definitions for industrial systems. This addresses the replacement of electro-mechanical safety systems with electronic safety built into the drive’s safety logic. The white paper also addresses the EU Machinery Directive and harmonized standards, and ABB drives safety offering. […]
Installing an ABB drive on a mechanical agitator at a production bottleneck has reduced stoppages, cut maintenance and saved energy. Bairds Malt has five malt houses across England and Scotland, supplying 250,000 tonnes of malt a year to brewers and distillers. The ABB ACS880 industrial drive controls four gear motors located on the corners of […]
Virtual engineering and commissioning allow machine builders to develop and simulate entire industrial processing lines and machines without running hardware. This provides them with invaluable savings and other benefits through the designing, commissioning and operating phases of ABB enabled machines. ABB’s Virtual Commissioning platform lets them set up virtual drives for offline simulation, eliminating the […]
Initially, DC drives were used for variable speed control because they achieved good torque and speed response with high accuracy. DC offers accurate and fast torque control, high dynamic speed response and is simple to control. However, while a DC drive produces an easily controlled torque from zero to base speed and beyond, the motor’s […]
When refurbishing machines, converting from DC to AC motors and drives has many advantages. They include the use of AC variable speed drives to improve reliability, reduce running costs and provide energy savings. Over 20 years ago DC motors and drives dominated many markets and industries. The reason was that only DC motors could […]
