National Instruments 779035-02

The National Instruments part number 779035-02 corresponds to the PXI-7332 PXI Motion Control Module, designed for advanced motion control applications. This module provides robust support for linear interpolation and sophisticated stepper generation, enabling precise motion control with 12-bit resolution for accurate positioning of controlled drives. The PXI-7332 features a trajectory update rate spanning from 62.5 to 500 µs per sample, ensuring swift responsiveness to motion commands and adjustments. Multi-axis synchronization is achieved with less than one update sample, promoting seamless coordination among multiple axes.

The module integrates with both the PXI trigger bus and RTSI bus, facilitating synchronized operations with additional PXI modules and control systems. It is compatible with various drive types including those from NI and other manufacturers, and it works with the NI-Motion driver software to support programming across several environments, such as Microsoft Visual Basic, LabVIEW, and Microsoft Visual C++. The PXI-7332 incorporates four 8-bit TTL ports capable of sourcing or sinking 24 mA, alongside two open-loop PWM outputs for enhanced control functionalities.

For connectivity, it features a reliable 68-pin female high-density VHDCI type connector for motion I/O. The module operates at +5 VDC (±5%) and requires a power supply of 1 A, with a maximum power consumption of 5.7 Watts. Safety is prioritized with a built-in watchdog timer, which resets the module in the event of a fault, and a shutdown input that can be set to stop all axis operations and common outputs. It is essential to operate the PXI-7332 in environments with a maximum temperature of 55 degrees Celsius and humidity levels below 85%. Please note that the module lacks an Ingress protection rating, and it is advised to keep it away from harsh industrial conditions that may compromise performance and longevity.
