PXI-7344

PXI motion control module

4-axis, stepper/servo PXI Motion Controller module - PXI‑7344 is suitable for both simple and complex motion applications. It includes two processors and a real-time onboard system with multi-axis interpolation. The PXI‑7344 provides hybrid motion trajectory control and fully coordinated circular, linear, point-to-point, gear and vector space control for embedded real-time motion operations or host-centric programming environments.

NI provides contour control for more complex movements. The on-board CPU uses an embedded real-time operating system to implement event-based multi-task control. With this approach, multiple motion control programs and processes can run synchronously on the controller independently of the host PC and without external programming interaction unless the host program or user configuration actively initiates the interaction.

With the NI PXI 7340 (Part number: 779036-02 and 777935-01) motion controllers, users can coordinate motion control synchronously with up to 4 axes in preemptive, multitasking, constant conditions. This model offers an advanced dual-processor architecture that uses a 32-bit CPU in combination with a digital signal processor (DSP) and a custom FPGA to give this motion controller exceptional functionality. The FIFO bus interface and strong capacity set provide fast communication while offloading complex motion capacity from the host PC to optimize frame 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 DSP for all closed loop control, including position tracking, PID closed loop control calculation and motion trajectory generation. The DSP chip is powered by custom FPgas that perform fast encoder interfaces, position capture and breakpoint functions, motion I/O processing, and step pulse generation for hard real-time functionality. The CPU inserted in this model runs into a multi-tasking, constant-working framework and handles host communication, command processing, multi-axis interpolation, error handling, universal digital I/O, and overall motion framework integration capabilities.
