4-Axis, Stepper/Servo PXI Motion Controller Module—The PXI‑7344 is recommended for both simple and complex motion applications. It includes dual processors, a real-time onboard OS, and multiaxis interpolation. The PXI‑7344 offers blended motion trajectory control and fully coordinated circular, linear, point‑to‑point, gearing, and vector-space control in either embedded motion operation or host-centric programming environments. NI provides contouring capability for more complex moves. The onboard CPU uses an embedded real-time OS that has event-driven multitasking control. With this approach, several motion control programs and processes can operate simultaneously on the controller independently of the host PC and with no outside program interaction unless the host program or user configuration initiates it.
