The National Instruments PXI-7344 (Part Number: 777935-01) is a sophisticated 4-axis stepper and servo motion controller module designed for PXI, PCI, and 1394 bus computing systems. Engineered for advanced motion control applications, this module enables real-time execution of up to 10 motion programs simultaneously in a preemptive multitasking operating system environment. The PXI-7344 features enhanced PID/PIVff servo updates at a remarkable rate of 62 microseconds per axis. It includes comprehensive motion input/output capabilities, incorporating home switch inputs, breakpoint outputs, end-of-travel limits, and trigger inputs, supporting encoder feedback rates of up to 20 MHz.

This model is equipped with 32 digital I/O bits and provides a 12-bit analog input resolution across eight multiplexed analog input channels, alongside four analog output channels. It also features four 8-bit digital I/O ports, allowing for extensive connectivity options. The PXI-7344 supports the National Instruments Real-Time System Integration (RTSI) bus, facilitating high-speed synchronization between various National Instruments hardware, including data acquisition and image acquisition devices. This capability is vital for applications requiring coordinated timing and triggering across multiple systems.

A high-density 68-pin female VHDCI connector is provided for Motion I/O connections, ensuring versatile integration options. The PXI-7344 is compatible with a range of application software, including LabVIEW, LabWindows/CVI, and BridgeVIEW, enabling the creation of standalone executable programs through the FlexMotion software. Additionally, the FlexMotion VI Library offers a collection of virtual instruments designed specifically for use with LabVIEW and the PXI-7344, providing essential resources for custom automation solutions. This controller operates effectively within a temperature range of 0 to 55 °C. Although National Instruments has designated the PXI-7344 as obsolete, Apex Waves remains committed to providing both purchase and repair services for this motion controller indefinitely.
