National Instruments PXI-7332

The National Instruments PXI-7332 is a sophisticated 2-Axis Stepper Motion Controller Module designed for high-performance point-to-point motion control applications. This module integrates seamlessly into real-time systems, allowing for direct communication with various image acquisition and data acquisition hardware. It features advanced capabilities such as linear interpolation and high-level stepper generation to ensure smooth motion profiles and increased operational velocities. The PXI-7332 is compatible with the PXI trigger bus and RTSI bus, making it versatile in multiple setups.

For operation, the PXI-7332 requires a computer equipped with a PCI or PXI slot and is compatible with both NI and third-party drives and motors. It operates with the NI-motion driver software, which is included at no extra cost, and supports various software environments including Microsoft Visual Basic, LabVIEW, and Microsoft Visual C++. The module provides significant performance features, including a trajectory update rate ranging from 62.5 to 500 µs/sample and high-speed multi-axis synchronization at under 1 update sample.

Additionally, the PXI-7332 includes four 8-bit TTL ports capable of sourcing or sinking 24 mA outputs, along with multiple open-loop PWM outputs. Connections are facilitated through a 68-pin female high-density VHDCI type connector. The device requires 1 A of power at +5 VDC (±5%) and has a maximum power consumption of 5.7 W. Safety features, including a watchdog timer and shutdown input, are integrated to ensure reliable performance by resetting the module to its initial state and halting all axis motion as needed. While the PXI-7332 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves.
