One Network from IT to Motion Control
Features 7/23/2010 Post a comment Machine builders achieve new levels of design flexibility by using the standard Ethernet network platform to connect devices across the enterprise and an entire machine, including variable frequency drives and servo drives for integrated motion control.
Anti-resonance and Vibration Suppression Application in Servo Systems
Features 7/2/2010 Post a comment Vibrations, resonances, and oscillations can cause problems in a servo-motor application. But when you turn down the control-loop gains, the driven machine responds more slowly. So what do you do when the tuning gains that run the machine with fast settling time cause it to screech and oscillate out of control?
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
