The National Instruments PXI-7358 Stepper/Servo Motion Controller Module (Part Number: 778540-08) is a high-performance motion control solution designed for the PXI platform, capable of managing eight axes for a diverse range of motion applications. This versatile module allows for independent configuration of each axis, supporting both stepper and brushed servo control modes. It includes eight 16-bit analog-to-digital converters for localized data acquisition, as well as advanced features for motion trajectory planning and triggering.

The PXI-7358 provides a voltage range of +/- 10 V, with a resolution of 16 bits, and accommodates a velocity range from 1 to 8,000,000 steps per second, and acceleration of +/- 1,200,000 steps per second. Additionally, it supports up to +/- 256,000 revolutions per second, with a programmable offset and limit configurations. Equipped with 64 digital I/O channels, the module integrates seamlessly with NI-Motion driver software and supports application development environments such as LabVIEW, LabWindows/CVI, Microsoft Visual C++, and Microsoft Visual Basic.

Buffered breakpoints enhance timing accuracy between motion and measurements or vision systems, enabling users to send a buffer of position breakpoints that can trigger an output signal upon reaching target positions. Triggering can occur at rates up to 2 kHz for individual breakpoints and up to 4 MHz for periodic breakpoints.

While the PXI-7358 has been declared obsolete by National Instruments, it remains available for purchase and repair through Apex Waves. The module features a compact 1-slot 3U PXI form factor, operates within an ambient temperature range of 0 to 55 °C, and has a maximum power consumption of 18 W. For users seeking further information, the user and maintenance manuals can be downloaded, and pricing inquiries should be directed to a sales representative.
