National Instruments PXI-7350 Servo/Stepper Motion Controller Module

The PXI-7350 (Part Numbers: 778540-02, 778540-04, 778540-06, and 778540-08) Servo/Stepper Motion Controller Module is suited for straightforward and complex motion applications and is equipped with 2 to 8 axes. The part numbers correspond with different models in the series, depending on how many axes they have. The PXI-7352 (Part Number: 778540-02 ) is a 2-Axis module, the PXI-7354 (Part Number: 778540-04 ) is a 4-Axis module, the PXI-7356 (Part Number: 778540-06 ) is a 6-Axis module, and the PXI-7358 (Part Number: 778540-08 ) is a 8-Axis module. 

This module offers combined motion path control and circular, linear, point-to-point, and completely coordinated vector control in inserted constant task or programming conditions. The NI PXI-7350 incorporates eight 32-bit analog-digital converters (multiplexed and single-ended) for inner data acquisition and a server for advanced motion and trigger path features. It has a PID update rate range of 62.5 us/sample to 5 ms/sample. The module also offers sinusoidal switching, which makes it a brushless motor controller.

The PXI-7350 Motion Controller Module provides buffered breakpoints for exact timing between motion and measurements or vision. With this feature, the user can transmit a buffer of position breakpoints to the controller that trigger a digital signal after reaching the positions in the buffer.
The ANSI C-based LabWindows/CVI is one of the software choices for the NI PXI-7350, which includes intuitive graphics and a state-of-the-art UI. Utilizing LabWindows/CVI, the user can create C code for custom data acquisition, test, estimation, and mechanization arrangements. The NI-Motion programming incorporates a progression of example programs for utilizing LabWindows/CVI with National Instruments motion control hardware.

The NI PXI-7350 can also be used with NI Motion Assistant, which offers a point-and-click interface for making movement control arrangements rapidly and effectively. When the user has made a motion assignment, they can utilize Motion Assistant to output the task in LabVIEW code or code creations. The NI PXI-7350 Controller Module utilizes the DSP for all closed-loop control, including position tracking, PID control closed-loop, and motion trajectory generation. The DSP chip is supported by a custom FPGA that performs the fast encoder interfacing, position catch and breakpoint (position compare) functions, motion I/O processing, and stepper pulse generation for hard real-time functionality.

The installed CPU in this module runs a multitasking real-time working framework and handles host communications, command processing, multi-axis interpolation, onboard program execution, error handling, general-purpose digital I/O, and overall motion framework integration capacities. The NI device weighs 6 oz, and measures 6.3 x 3.9 in. in physical dimensions.

The PXI-7350 is no longer available from National Instruments, but the PXI Motion Control Module remains available in perpetuity from Apex Waves for both purchase or repair services.
