Taking kinematics to the next level
10 June 2014
TwinCAT Kinematic Transformation, from Beckhoff, is said to enable machine manufacturers and users to control robots and their own complex kinematic constructions directly from within the TwinCAT software platform.
TwinCAT Kinematic Transformation offers numerous kinematics that are divided into three different product levels, depending on their complexity.
These include 2D, shear, 3D Delta and SCARA kinematics. The new Level 4 version represents a consistent extension of the range of functions, allowing more complex kinematics to be implemented.
Examples are serial 6-axis kinematics and the Steward platform.
TwinCAT performs the set value generation and necessary kinematic transformations. The set values for the axes are cyclically transferred via EtherCAT to the drive amplifier – for example an AX5000 servo drive. The robot movements are programmed directly from the PLC. Path movements for following contours can also be implemented with TwinCAT NC I, according to DIN 66025.
With TwinCAT Kinematic Transformation an additional robot controller, and therefore the need to learn a special robot programming language, is not required. Accordingly, the entire machine can be operated with just one control CPU.
