Overview

Product overview

Key product information and technical features.

The PXI-7358 supports blended trajectories and coordinated circular, linear, point-to-point, gearing and vector-space motion. Motion operations can run in embedded real-time or host-centric programming environments.

NI-Motion lets users start all axes together while assigning acceleration and velocity profiles to each axis. Onboard analog inputs and digital I/O complement the motion-control functions.

  • Eight-axis stepper/servo control.
  • Sinusoidal commutation for brushless motor control.
  • Coordinated circular and linear motion with trajectory blending.
  • Onboard 16-bit analog acquisition and 64 digital I/O channels.
