Check the listing for details. National Instruments NI PCI-7340 / PCI-7344 Motion Controller Card, 4-Axis. Condition: Used. Listed at 795.00 USD. National Instruments PCI-7344 motion controller card for 4-axis stepper or DC servo motor control. Confirmed to successfully initialize under NI MAX and guaranteed to be fully functional. Compatible with the current NI-Motion software.4-Axis, Stepper/Servo Motion Controller Device—The PCI‑7344 is recommended for both simple and complex motion applications. The PCI‑7344 includes dual processors, a real-time onboard OS, and multiaxis interpolation. The PCI‑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. The PCI‑7344 also provides contouring capability for complex moves. The onboard CPU uses an embedded real-time OS with event-driven multitasking control. With this approach, several motion control programs and processes can operate simultaneously on the controller, independent of the host PC and with no outside interaction unless the host program or user configuration initiates it.
