Altivar ATV31 VSD

The ATV31HU55N4, a remarkable variable speed drive from the Altivar series, is a sophisticated and versatile component designed to optimize the performance of simple machines across a wide range of industrial applications. With its compact assembly style, integrated EMC filter, and robust IP20 protection rating, this drive unit represents a pinnacle of engineering innovation.


Central to its capabilities is its adaptability to a 3-phase supply network, with a rated voltage spanning from 380 to 500 volts, encompassing a 5.5 kW power range. Its ability to function seamlessly within a frequency range of 50 to 60 Hz further solidifies its versatility. This makes the ATV31HU55N4 ideal for applications requiring precision control, such as in modern manufacturing and automation processes.

One of the key highlights of the ATV31HU55N4 is its advanced control over asynchronous motors. Factory-set for constant torque, the drive employs sensorless flux vector control with PWM-type motor control signals. Its three analog input channels enable precise motor control and regulation.


Designed to cater to both simple machines and more complex systems, the ATV31HU55N4 is equipped with an integrated EMC filter, which plays a pivotal role in reducing electromagnetic interference and ensuring optimal performance. This feature is particularly vital in environments where precision and stability are paramount.


Operating within a three-phase network, the ATV31HU55N4 exhibits a line current of 16.5 A at 500 V and 21.9 A at 380 V. Its nominal output current is 14.3 A at 4 kHz, with a maximum transient current of 21.5 A for 60 seconds. The drive showcases an impressive peak power dissipation of 232 W at nominal load, a testament to its efficient energy management capabilities.

The Schneider Electric ATV31HU55N4 drive unit offers a plethora of adjustable parameters. Its regulation loop employs a Frequency PI regulator, ensuring smooth and consistent motor performance. Furthermore, the ATV31HU55N4 allows for motor slip compensation, which is automatically adjusted based on the load, ensuring efficient operation regardless of the workload.

In terms of environmental robustness, the ATV31HU55N4 is built to withstand a spectrum of conditions. With a dielectric strength of 2410 V DC between earth and power terminals and 3400 V AC between control and power terminals, it offers reliable protection against electrical disturbances. Its vibration resistance, shock resistance, and wide operating temperature range further underscore its durability and suitability for demanding industrial environments.


For utmost convenience, the ATV31HU55N4 incorporates a user-friendly display featuring LED indicators for drive voltage and four 7-segment displays for CANopen bus status. This intuitive interface enhances the monitoring and management of the drive's performance.


Connectivity is a hallmark of the ATV31HU55N4. It offers a range of physical interfaces, including an RJ45 connector for CANopen via the VW3 CANTAP2 adaptor and another RJ45 for Modbus communication. This enables seamless integration into industrial networks and systems, facilitating real-time data exchange and remote management.

In conclusion, the ATV31HU55N4 variable speed drive is a true testament to engineering excellence. With precise control, robust design, and advanced features, the ATV31HU55N4 optimizes processes, enhances efficiency, and ensures consistent and reliable performance.
