Event-driven Motion Control
Using flexible profiles and integrating event-driven strategies into motion control schemes help optimize automation systems.

Integrating event-driven strategies into motion control schemes may optimize automation systems beyond what’s possible with traditional electronic cams or motion profiles. Until now, such strategies have tended to be limited by point-to-point motions and ad hoc methods. A flexible profile technology, as provided by Bosch Rexroth, provides a structure for event-driven strategies to be fully realized. Servo motors have largely replaced mechanical cams as the standard means of meeting the motion demands of the automation industry. The reasons are well-known: Mechanical simplicity and system configurability are the two most common, but improved synchronization, ease of machine servicing, and elimination of wear parts, among other benefits, are often cited. Even when not physically present, the influence of mechanical cams may still be felt. Cams continue to shape machine building and automation system programming when engineers think in terms of “electronic cams” and their associated cam tables. In packaging machines, that makes sense; since they require repetitive motions, the cam paradigm fits.
