National Instruments PXI-7340 PXI Motion Controller

With the NI PXI 7340 (Part Numbers: 779036-02 and 777935-01) Motion Controller, the user can take advantage of as many as four axes of synchronous, coordinated motion control in a preemptive, multitasking, constant condition. This model offers progressed double-processor architecture that uses a 32-bit CPU combined with a digital signal processor (DSP) and custom FPGAs to give this Motion Controller superior abilities. The FIFO bus interface and intense capacity set give fast communications, while off-loading complex motion capacities from the host PC for optimized framework execution. The PXI 7340 has 8 analog inputs and 4 analog outputs. It has a maximum update rate of 62.5 us/axis.

The NI PXI-7340 Motion Controller utilizes the DSP for all closed-loop control, including position tracking, PID closed-loop control computation, and motion trajectory generation. The DSP chip is supported by custom FPGAs that perform the rapid encoder interfacing, position catch and breakpoint functions, motion I/O processing, and stepper pulse generation for hard real-time functionality. The inserted CPU in this model runs to multitasking, constant working framework and handles host communications, command processing, multi-axis interpolation, error handling, general-purpose digital I/O, and overall motion framework integration capacities.

The embedded firmware depends on an installed RTOS piece and gives ideal framework execution in different motion applications. Motion tasks are organized. Task execution order relies upon the need of each task, the condition of the whole motion framework, I/O or other framework events, and the real-time clock

The PXI 7340 is run using the NI-Motion driver software which is compatible with software packages/application development environments (ADES) such as LabVIEW, LabWindows/CVI, Microsoft Visual C++, Microsoft Visual Basic, and AKD WorkBench software. The device hardware can be configured using the Measurement & Automation Explorer (MAX) tool.

The NI PXI 7340 Motion Controller direction generators figure the quick position charge that controls increasing speed and speed while it moves the hub to its objective position. Contingent upon how the user designs the hub, this order is then sent to the PID servo circle or stepper beat generator.

The NI device weighs 6 oz, and measures 6.3 x 3.9 in. in physical dimensions.
