Overview

Product overview

Key product information and technical features.

The PCI-7334 provides programmable stepper motion control for independent axes or coordinated straight-line moves. It fits PCI-based motion systems requiring point-to-point positioning.

NI documents real-time integration with data acquisition and image acquisition hardware, allowing motion control to form part of a larger measurement or imaging system.

Four axes of stepper motion control.
Linear interpolation for coordinating multiple axes.
Stepper pulse generation designed for smooth motion at high velocities.
Supports step/direction or clockwise/counterclockwise digital command outputs.
Supports open-loop and closed-loop stepper operation.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

How many axes does the PCI-7334 control?

It controls four stepper axes and supports linear interpolation for coordinated motion.

Can the PCI-7334 operate with encoder feedback?

Yes. NI documents closed-loop stepper operation with encoder feedback, as well as open-loop operation.

Which software does NI document for controller configuration?

NI's setup procedure uses the NI-Motion driver and Measurement & Automation Explorer (MAX). Verify the applicable driver release and operating-system requirements for your system.
