These low-cost motion controllers provide new solutions for machine builders who need simple, straightforward motion control without a lot of extra features. Unlike other low-cost motion controllers, NI 7330 controllers still have a variety of powerful features including: • Linear interpolation for coordinating multiple axes. • Real-time system integration for directly communicating with data acquisition or image acquisition boards • High-performance stepper generation for ensuring smooth motion at high velocities. NI-Motion Driver Software NI 7330 devices use the NI-Motion driver. The advantage of this is that if your application needs change in the future, you can easily upgrade your hardware without having to change your code. You can also take advantage of any firmware updates with the fieldupgradable firmware.

NI 7330 Series Features Integration Capabilities Like other NI Motion controllers, NI 7330 controllers offer powerful integration capabilities with both data acquisition and machine vision. One of the most powerful is the RTSI bus or PXI trigger bus capability that you can use to communicate directly with other devices without extra wiring and without consuming bandwidth on the host bus. An NI 7330 is ideal when using stepper motors for applications where only simple motion is required. 638 National Instruments • Tel: (800) 433-3488 • Fax: (512) 683-9300 • info@ni.com • ni.com Low-Cost Stepper Motion Controllers Low-Cost Stepper Controller Technical Support for Motion Software As a complement to your motion software product, consider: Technical Support – FREE through applications engineers worldwide, Web resources, and Premier Support – ni.com/support Motion Control Fundamentals Training – Instructor-led courses – ni.com/training Professional Services – Feasibility, consulting, and integration through our Alliance Program members – ni.com/alliance For more information on NI services and support, visit ni.com/services Ordering Information NI PCI-7334 (4-axis stepper) ......................................778417-01 NI PXI-7334 (4-axis stepper) ......................................778444-01 Includes hardware and NI-Motion software, libraries, and examples Accessories NI Motion Assistant......................................................778553-01 Universal Motion Interfaces ......................................see page 640 Drives..........................................................................see page 642 Cables..........................................................................see page 645 BUY ONLINE!
