NI LabVIEW FPGA-powered frame grabber and motion drive help engineers create custom inspection and machine control solutions.
National Instruments has introduced two new additions to its NI reconfigurable I/O (RIO) technology including a reconfigurable Camera Link frame grabber for demanding embedded vision applications and a motion module for the NI CompactRIO platform.
The NI PCIe-1473R frame grabber is a PC-based embedded vision board that combines field-programmable gate array (FPGA) technology with a Camera Link interface to help engineers create high-performance embedded imaging and inspection applications.
The NI 9502 brushless servo drive C Series module makes it possible for engineers to drive brushless servo motors, including six new custom NI motor options, directly from the reconfigurable CompactRIO system to address advanced motion control challenges.
The NI PCIe-1473R frame grabber is suitable for advanced inspection and imaging applications that require image pre-processing and high-speed control such as medical imaging, web and surface inspection and high-speed sorting. Engineers and scientists can program the frame grabber’s onboard FPGA with the NI LabVIEW FPGA module for custom image processing and analysis in real time, with little to no CPU intervention. The frame grabber combines the onboard FPGA with a high-bandwidth 850 MB/s Camera Link bus, which supports a range of Camera Link configurations up to 10 taps and 80 bits. The NI PCIe-1473R also supports Power over Camera Link (PoCL) to directly power cameras with no additional cables or external power supply. With such features, the frame grabber is an off-the-shelf solution that makes it possible to create high-performance imaging applications without spending substantial time and money to develop a custom design.
With the addition of the NI 9502 motion drive module for CompactRIO, engineers can now power brushless, stepper or brushed servo motors directly with NI C Series modules to provide a compact, highly customisable solution for integrating motion into advanced control, monitoring and test systems. The NI 9502 offers 4 A continuous/8 A peak current and multiple commutation modes. To complement the module, NI is also releasing six three-phase brushless motors that are specifically designed for maximum performance and direct connectivity with the NI 9502. With these features, the NI 9502 helps engineers implement proprietary custom drive control algorithms at the FPGA level through LabVIEW FPGA, eliminating the need for custom firmware from a drive manufacturer.
