The NI 9502 is a one-axis C Series motor drive module capable of 4 A continuous, 8 A peak current output to drive three phase brushless servo motors (BLDC or BLAC PMSM). Motor control (traditionally fixed in drive firmware) is implemented on an NI CompactRIO chassis field-programmable gate array (FPGA) and is fully customizable in LabVIEW FPGA with LabVIEW NI SoftMotion Module motor control VIs.

The NI 9502 provides an alternative to expensive and time-consuming custom drive development or exposing proprietary IP to a drive vendor and paying for custom firmware. You can implement custom drive functionality directly on the CompactRIO chassis FPGA and connect each motor directly to an NI 9502, which eliminates large stand-alone motor drives and unwieldy cabling from multiaxis embedded motion systems.

The NI 9502 can operate in either trapezoidal or field-oriented control (FOC) commutation mode, and you can use it in any CompactRIO chassis, including EtherCAT, MXI-Express, and Ethernet expansion chassis. Hall sensors (5 V) and motor phases (24 V) must be independently powered, and external encoder feedback is required for most operation modes. (The NI 9411 is recommended for encoder feedback, which can also provide Hall sensor power. The NI PS-16 24 V supply is recommended for motor power.)

The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
