选择运动控制卡： PCI还是PXI？

[wlan]

大家好！

想请问一下，我想买一张能同时实时控制8个马达的运动控制卡，现在发现有NI PXI-7358和NI PCI-7358两种可供选择。

由于我是个新手，对于选择硬件也没有什么经验，所以想请问大家：PCI和PXI卡到底有什么区别，如何选择？

谢谢！

个人认为PXI和PCI的区别在于PXI卡插在PXI机箱上自动实现时钟的同步，且插拔方便；而2块PCI卡要实现同步则要另外加控制线，实际上PXI就是extra－PCI。如果你没有PXI机箱，买PXI卡就没有意义了。

谢谢大家。不好意思我忘记写了，我的马达是Faulhaber公司的Brushless Servo Motor 3564 024BC。

大家教教我选择运动控制卡吧，对了，是不是还另外需要别的硬件比如说Drive呢？

need a motor driver (hardware), you can buy Panasonic. or the other.

You can purchase or make it yourself. I usually make by myself. but you must know where the corresponding pin assignment are about.
