Overview

Product overview

Key product information and technical features.

The PXI-7344 provides independent or coordinated motion control. Its dual-processor architecture and embedded real-time operating system allow motion programs to run on the controller rather than relying entirely on host execution.

Dedicated motion connections include encoder feedback, limit and home inputs, and analog inputs. The hardware manual documents signal assignments and electrical requirements for integrating external motion equipment.

Coordinated linear, circular, point-to-point, gearing, and vector-space motion.
Contouring and blended trajectory control.
Onboard multitasking motion-program execution.
Encoder and analog feedback resources.
