B&R is introducing the Generic Motion Control platform that includes drives, movement and path control, visualisation and I/O handling. Machine builders and system integrators typically need to integrate movement and path control, connect drives and use functions such as visualisation, I/O processing and communications. Until now, this has been difficult because suitable systems for this type of homogeneous integration were not available.
Anthropomorphic robots, complex CNC 3D processing, multiple linked-axis movements and single-axis positioning that can be modified in real-time have traditionally been separate areas of technology. However, B&R is introducing the General Motion Control platform that combines all components in one system. In particular, path control with CNC functionality works as an integral part of the complete automation system, which can be configured with a single software tool.
The system is extremely versatile because the real-time operating system creates the environment needed for high-precision positioning tasks. CNC cycle times of 400us enable sub-micron path precision to be achieved. Generated set positions are transferred to the drive without jitter via Powerlink. Additionally, the required I/O points can be added to the system in an extremely flexible manner.
Predefined visualisation components can also be used to create complex machine functions. In addition to 'classic' components such as parameter configuration and movement program operation, this also includes tools for simulation, logging and process diagnostics. This provides the foundation for custom visualisation. The flexible system architecture and the large number of functions make it possible to customise machine lines to meet specific application requirements.
The Soft CNC has an extensive list of functions. Part programs and movement procedures are programmed according to DIN 66025. Division into main and sub-programs enables clear management of NC programs. Helpful functions have also been added to the basic functions defined in the standard. The extended programming techniques permit the use of elements from a high-level language, such as loops, conditional statements and branches.
Data from application programs on the PLC is exchanged using a powerful interface. Various access functions enable program execution to be controlled in real-time. Data, such as the tool radius or even end points of path sections, can be changed while the program is being executed, and certain data is available synchronous to the path.
