Raspberry Pi Motion Control


       Amtech bring you Pi-Motion! The ultimate low cost, touch screen motion control system. Bringing together the Raspberry Pi with its high level of functionality, LAN-Motion our latest high performance multi axes control card and GNC motion control software. Pi-Motion is an extremely powerful multi axes control system. At the heart of the system is a Raspberry Pi computer which is running on a 64 bit quad-core ARM Cortex processor. The motion controller is based on a fast 32-bit RISC processor with a floating point co-processor. These two device communicate over 10/100 Ethernet interface, and is capable of transferring 8000 program blocks per minute.
       The controls user interface is provided by GNC motion control software, giving a truly intuitive operator interface. The combination of these products offers a flexible and affordable motion control solution, for use in a wide variety of industrial applications. 
The panel mount enclosure which is rated to IP65, can be used to house the touch screen and processor to give it extra protection, for use in industrial environments. The fact that it can be panel mounted simplifies the installation of this control system
