PCI-7344 运动控制器设备

4-axis stepper/servo motion controller device – PCI‑7344 is suitable for both simple and complex motion applications. PCI‑7344 includes two processors and a real-time onboard system with multi-axis interpolation. PCI‑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.
PCI‑7344 also provides contour control for 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, independent of the host PC, and without external interaction, unless the host program or user is configured to actively initiate the interaction.

Featured with 3D contouring, 3D linear and circular interpolation, and up to 62 ms PID loop update rate, the National Instruments PCI-7344 (Part number: 778916-04) is a high-quality Motion Controller for stepper/servo control applications. This device is well-suited for machine builders and end users who require the capability of creating powerful applications swiftly and effortlessly. This device has a unique construction in which the DSP and CPU operate together to provide the user with optimized closed-loop controlling, motion command processing, and automated systems controlling. The NI PCI-7344 Motion Control Board comes with integrated system safety mechanisms. For example, the watchdog timer function has 63 ms timeout and resets the board to the startup state.

The NI PCI-7344 has 62.5 to 500 µs/sample trajectory update range and offers 62.5 µs/axis maximum update range. This Motion Controller enables the user to acquire stepper outputs at 4 MHz maximum pulse rate and 120 ns maximum pulse width over a voltage range of 0 to 5 V.

The PCI-7344 National Instruments offers four 8-bit digital I/O ports; each bit can be programmed individually. For motion controlling and digital I/O, two separate 68-pin female high-density VHDCI I/O connectors are provided. The motion I/O connector incorporated in this Motion Controller contains all necessary signals required to control as many as four axes of stepper and servo motion, including: inhibit outputs, breakpoint outputs, motor command outputs, reverse limit inputs, home limit inputs, and more. For high-speed connectivity between the NI Motion Controller PCI-7344 and other National instruments devices, the user can utilize the RTSI connector provided.
