3. Advantages and Features
- Multi-Axis Synchronization: Coordinates up to 4 axes for complex motion profiles (e.g., linear interpolation, circular arcs).
- Real-Time Performance: 20 kHz position update rate ensures minimal latency for dynamic applications.
- Flexible Control Modes: Supports velocity, torque, and position control with customizable PID parameters.
- Easy Integration: Pre-built drivers and LabVIEW modules reduce development time by 30% compared to custom solutions.
- Compact Design: 3U PXI form factor saves space in industrial environments.
4. Application Areas and Case Studies
Industries:
- Industrial automation (pick-and-place systems)
- Robotics (SCARA, Cartesian robots)
- Semiconductor manufacturing (wafer handling)
Case Study:
A leading electronics manufacturer improved assembly line efficiency by 25% using the PXI-7344 to control a 4-axis SCARA robot. The controller’s real-time trajectory planning minimized cycle times while maintaining micron-level precision, reducing defective products by 15%.
5. Competitor Comparison
Compared to legacy motion controllers, the PXI-7344 offers:
- Scalability: Expandable via PXI modules (e.g., analog I/O, vision systems).
- Software-Defined Flexibility: Customizable logic in LabVIEW without hardware modifications.
- Cost-Effectiveness: Lower maintenance costs due to standardized PXI components.

6. Selection Recommendations
- Axis Requirements: Opt for the PXI-7344 for 4-axis systems; consider the PXI-7358 for 8-axis needs.
- Environment: Use shielded cables in high-EMI environments to prevent signal interference.
- Software: Pair with LabVIEW for rapid prototyping or TestStand for automated test sequences.
7. Precautions
- Installation: Ground the chassis properly to avoid electrostatic discharge (ESD) damage.
- Motor Matching: Ensure motor torque and encoder resolution align with application requirements.
- Firmware Updates: Regularly update NI drivers to access new features and bug fixes.
