Key Features and Benefits

1. Power and Performance

The ATV930U55N4 delivers 5.5 kW of power, making it ideal for medium-sized industrial motors. Its vector control technology ensures high-precision speed and torque regulation, even under varying loads. This is critical for applications like conveyors, pumps, and fans, where consistent performance is essential.

2. Integrated Braking Unit

The built-in braking chopper eliminates the need for external braking resistors, reducing installation complexity and costs. It enables rapid deceleration of high-inertia loads, such as centrifuges or cranes, by dissipating regenerative energy safely.

3. Advanced Control Modes

  • V/F Closed-Loop Control: Suitable for standard applications requiring speed stability.
  • Vector Control: Optimized for dynamic applications needing precise torque control (e.g., extruders, mixers).
  • Synchronous Motor Support: Compatible with permanent magnet synchronous motors (PMSM) and synchronous reluctance motors (SynRM), offering energy savings of up to 30% compared to induction motors.

4. Connectivity and Integration

With support for multiple industrial protocols (Ethernet/IP, Modbus TCP, Profibus, etc.), the ATV930U55N4 seamlessly integrates into existing automation systems. Its modular design allows expansion with I/O, encoder, and safety modules, enhancing flexibility.

5. Robust Design

  • IP21 Protection: Suitable for indoor environments, protecting against dust (≥12 mm particles) and vertical water droplets.
  • Wide Temperature Range: Operates from -10°C to +50°C, adapting to harsh industrial conditions.
  • Forced Ventilation: Ensures reliable cooling even in high-ambient-temperature settings.

6. Safety and Compliance

The drive meets global safety standards (SIL 3, STO) and includes features like safe torque off (STO) and safe stop 1 (SS1). It complies with EMC directives (EN/IEC 61800-3) and low-voltage directives, ensuring minimal electrical interference.

Applications

The ATV930U55N4 is versatile across industries:

  • Material Handling: Conveyors, cranes, and elevators benefit from its precise speed control and braking capabilities.
  • Process Industries: Pumps, compressors, and mixers require reliable torque regulation for consistent output.
  • Renewable Energy: Wind turbines and hydroelectric systems use its vector control for optimal energy capture.
  • HVAC Systems: Fans and blowers achieve energy savings through variable-speed operation.

Energy Efficiency and Sustainability

The ATV930U55N4 contributes to reduced energy consumption via:

  • Flux Optimization: Adjusts motor magnetization to minimize losses.
  • Sleep/Wake Functions: Powers down during idle periods and restarts automatically.
  • Harmonic Mitigation: Integrated EMC filters reduce grid distortion, avoiding penalties from utilities.

Installation and Maintenance

  • Wall-Mounted Design: Saves space and simplifies wiring.
  • User Interface: A detachable control panel with LCD allows local parameter adjustment.
  • Diagnostics: Real-time monitoring of currents, voltages, and temperatures prevents unexpected downtime.
  • Maintenance: Filter replacement and fan cleaning are required every 2–3 years, depending on operating conditions.

Conclusion

The Schneider Electric ATV930U55N4 is a feature-rich variable speed drive that balances performance, connectivity, and ease of use. Its integrated braking unit, advanced control modes, and compliance with industrial standards make it a reliable choice for demanding applications. By optimizing energy efficiency and reducing maintenance needs, it offers a low total cost of ownership, aligning with Industry 4.0 goals of smart, sustainable manufacturing.
