National Instruments PCI-7334

The National Instruments PCI-7334 is a versatile motion controller designed for PCI bus computers, offering advanced control features for complex motion tasks. This device supports fully programmable motion for up to four coordinated or independent axes, accommodating both stepper and servo motor applications. The PCI-7334 is equipped with a high-performance 32-bit Motorola MC68331 real-time processor, complemented by an ADSP-2185 DSP and FPGAs, enabling it to execute up to ten motion programs concurrently in a real-time multitasking environment. The motion control capabilities include both closed-loop servo control—utilizing analog inputs and quadrature encoders for precise feedback—and open or closed-loop operation for stepper motors.

The controller integrates user-friendly features, including non-dedicated I/O with four analog inputs and 32 digital I/O lines, all accessed via high-density 68-pin VHDCI connectors. The device supports a trajectory update rate range from 62.5 to 500 µs/sample, with a maximum step frequency of 4 MHz. Its capabilities extend to controlling a variety of servo devices, such as hydraulic systems and servo motors, while enabling smooth trajectory manipulation through a wide velocity range of 1 to 4,000,000 steps/s. Full compatibility with the NI-Motion software driver enhances the ease of integration, requiring an Application Development Environment such as LabVIEW or LabWindows/CVI.

Although the PCI-7334 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves. The device measures 6.9 inches by 3.9 inches and weighs 0.25 pounds, making it compact for integration into various setups. For detailed specifications and connectivity options, including specific cable requirements, users can consult the available user and maintenance manuals.
