Key Advantage: Multi-Axis Distributed Control

Machine designers are on a constant search to cram more speed, performance and complex motion profiles into todayís cutting-edge multi-axis automation solutions -- and that can place punishing demands on PLC-based centralized control architectures. Sercos was designed specifically to support more efficient distributed control architecture. Distributed control improves machine flexibility by moving processing power and decision-making from the CNC or motion control down into the drives and sensors.

Sercos is well-suited for distributed control because it supports the placement of axis dependant control functions, such as loop closures, interpolation and registration in the drives, not only in the motion controllerógiving the machine designer the option of having motion controllers concentrate on motion control profiles and tool paths independent of the axes.

Sercos also supports centralized control. With a minimum cycle time of 31.25 μs, it is possible to implement both distributed control drive concepts, with all control loops closed in the drive, or centralized signal processing concepts where only the current loop is closed in the drive and all other loops are handled by the motion controller. Sercos III is the only high-performance automation network that supports centralized and distributed drive concepts.  Next >>
