Schneider Electric ATV71HU40N4: Empowering High-Power Machines with Precision Control

The Schneider Electric ATV71HU40N4 is a highly advanced AC drive, part of the Altivar 71 series, known for its exceptional performance and precise control. Designed to meet the demands of complex, high-power machines, this variable-speed drive provides seamless motor control, enhanced energy adaptation, and reliable operation in industrial applications.

Unmatched Power and Versatility:

The ATV71HU40N4 offers impressive motor power, with a rating of 4 kW (5 hp) for 3-phase motors operating at 380-480 V. Its high line current of 11.5 A for 480 V 3 phases ensures that it can handle heavy loads efficiently. Additionally, the drive supports a wide output frequency range from 0.1 Hz to 599 Hz, allowing for precise speed control and application adaptability.

Advanced Sensorless Flux Vector Control (SFVC):

One of the key features of the ATV71HU40N4 is its Sensorless Flux Vector Control (SFVC) capability. This advanced control technique, based on either voltage or current vectors, ensures smooth and precise control of the motor's torque and speed. The SFVC system eliminates the need for external feedback sensors, simplifying installation and reducing maintenance requirements, while delivering reliable and efficient motor control.

Voltage/Frequency Ratio and Energy Adaptation:

The drive supports two or five points voltage/frequency ratios, providing flexibility in matching the motor's voltage and frequency characteristics for optimal performance. Additionally, the ATV71HU40N4 features an Energy Adaptation (ENA) system that efficiently handles unbalanced loads. This technology enhances the drive's ability to cope with dynamic loads, ensuring stability and consistent performance in real-world industrial applications.

Integrated EMC Filter for Noise Suppression:

Industrial environments are often susceptible to electromagnetic interference, which can affect the smooth operation of electronic equipment. To address this, the ATV71HU40N4 comes with an integrated EMC filter, providing effective electromagnetic noise suppression. This feature ensures reliable operation in noise-sensitive environments and compliance with electromagnetic compatibility (EMC) standards.

High Switching Frequency and Energy Efficiency:

The variable speed drive offers a nominal switching frequency of 4 kHz, which can be adjusted from 1 to 16 kHz to meet specific application requirements. This high switching frequency ensures precise motor control, reduced motor noise, and improved energy efficiency. The ATV71HU40N4 is designed to provide optimal performance even in high-speed applications.

Robust Design with Integrated Heat Sink:

The ATV71HU40N4 is engineered with a robust assembly style, featuring an integrated heat sink. This design ensures effective heat dissipation and reliable performance in challenging industrial environments. The integrated heat sink helps maintain the drive's efficiency and extends its service life, reducing the need for frequent maintenance.

User-Friendly Interface and Easy Connectivity:

The ATV71HU40N4 is equipped with a user-friendly interface, allowing operators to configure and monitor drive parameters with ease. Its intuitive keypad and graphical display provide real-time feedback, diagnostics, and parameter adjustments. The drive supports Modbus communication with no impedance, simplifying connectivity to external systems and enabling seamless integration into automation networks.


The Schneider Electric ATV71HU40N4 AC drive represents the pinnacle of precision control and power in the Altivar 71 series. Designed for complex, high-power machines, this variable-speed drive delivers exceptional motor control, energy adaptation, and versatility. Its advanced Sensorless Flux Vector Control (SFVC), voltage/frequency ratio options, and integrated EMC filter ensure reliable and efficient performance in diverse industrial applications. With its user-friendly interface, high switching frequency, and robust design, the ATV71HU40N4 empowers industrial processes with enhanced productivity and optimized energy consumption. Whether it's managing high-power motors or handling unbalanced loads, the ATV71HU40N4 sets a new standard for precision and efficiency in industrial automation.
