4軸步進(jìn)/伺服運(yùn)動(dòng)控制器設(shè)備- PCI – 7344適用于簡(jiǎn)單和復(fù)雜的運(yùn)動(dòng)應(yīng)用。PCI – 7344包括兩個(gè)處理器和一個(gè)帶有多軸插值的實(shí)時(shí)板載系統(tǒng)。PCI – 7344為嵌入式實(shí)時(shí)運(yùn)動(dòng)操作或以主機(jī)為中心的編程環(huán)境提供混合運(yùn)動(dòng)軌跡控制和完全協(xié)調(diào)的圓形、線性、點(diǎn)對(duì)點(diǎn)、齒輪和矢量空間控制。
PCI – 7344還為復(fù)雜的運(yùn)動(dòng)提供輪廓控制。板載CPU采用嵌入式實(shí)時(shí)操作系統(tǒng)，實(shí)現(xiàn)基于事件的多任務(wù)控制。通過(guò)這種方法，多個(gè)運(yùn)動(dòng)控制程序和進(jìn)程可以在控制器上同步運(yùn)行，獨(dú)立于主機(jī)PC，并且沒(méi)有外部交互，除非主機(jī)程序或用戶被配置為主動(dòng)啟動(dòng)交互。
美國(guó)國(guó)家儀器公司的PCI-7344(部件號(hào):778916-04)具有3D輪廓，3D線性和圓形插值，以及高達(dá)62 ms的PID環(huán)路更新速率，是一款高質(zhì)量的運(yùn)動(dòng)控制器，用于步進(jìn)/伺服控制應(yīng)用。該設(shè)備非常適合需要快速、輕松地創(chuàng)建強(qiáng)大應(yīng)用程序的機(jī)器制造商和最終用戶。該裝置具有獨(dú)特的結(jié)構(gòu)，DSP和CPU一起工作，為用戶提供優(yōu)化的閉環(huán)控制，運(yùn)動(dòng)命令處理和自動(dòng)化系統(tǒng)控制。NI PCI-7344運(yùn)動(dòng)控制板具有集成的系統(tǒng)安全機(jī)制。例如，看門(mén)狗定時(shí)器功能的超時(shí)時(shí)間為63毫秒，會(huì)將單板復(fù)位到啟動(dòng)狀態(tài)。
NI PCI-7344具有62.5至500μs/樣本軌跡更新范圍，并提供62.5μs/軸最大更新范圍。該運(yùn)動(dòng)控制器使用戶能夠在0至5 V的電壓范圍內(nèi)獲得4 MHz最大脈沖速率和120 ns最大脈沖寬度的步進(jìn)輸出。
PCI-7344國(guó)家儀器公司提供4個(gè)8位數(shù)字I/O端口;每個(gè)位可以單獨(dú)編程。對(duì)于運(yùn)動(dòng)控制和數(shù)字I/O，提供了兩個(gè)獨(dú)立的68針雌性高密度VHDCI I/O連接器。該運(yùn)動(dòng)控制器中包含的運(yùn)動(dòng)I/O連接器包含控制多達(dá)四軸步進(jìn)和伺服運(yùn)動(dòng)所需的所有必要信號(hào)，包括:抑制輸出，斷點(diǎn)輸出，電機(jī)命令輸出，反向限制輸入，home限制輸入等。對(duì)于NI運(yùn)動(dòng)控制器PCI-7344和其他國(guó)家儀器設(shè)備之間的高速連接，用戶可以利用提供的RTSI連接器。
PCI-7344 運(yùn)動(dòng)控制器設(shè)備
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.
