8.4.1 Basic signal flow
The main element of the technology application is the Motion Control Kernel.
• The Motion Control Kernel is controlled via a 32-bit double control word. All motion profiles in
the different operating modes can be controlled with this interface.
• Upstream to the Motion Control Kernel there is a so-called MCKInterface called which provides
additional process inputs for the application in order to control the Motion Control Kernel.
