Overview

Product overview

Key product information and technical features.

The PCI-7342 supports host-centric programming and embedded motion execution. Its onboard multitasking environment allows motion programs and processes to execute independently of continuous host-PC intervention.

The NI 7340 hardware manual covers controller installation, motion and digital I/O connections, encoder feedback, and electrical specifications. Use the two-axis configuration when interpreting family-level documentation for the PCI-7342.

  • Dual-processor architecture for onboard motion processing.
  • Coordinated linear, circular, point-to-point, gearing, and vector-space control.
  • Blended trajectories and contouring for complex moves.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PCI-7342 control two axes or four?

The PCI-7342 controls two axes. Four-axis descriptions refer to other configurations in the 7340 family, not this model.

Can stepper and servo axes be mixed?

Yes. Each axis can be configured independently for stepper or servo control.

Does the PCI-7342 power motors directly?

No. An external motor drive or amplifier supplies motor power; the controller provides motion command and interface signals.
