Its compact design, integrated EMC filter, and advanced control capabilities make it an essential choice for industries that require precise motor control and reliable performance.

Power and Voltage Specifications

The ATV320U55N4B operates on a three-phase power supply with a 380 to 500 V voltage range, accommodating variations between -15% to +10% of rated voltage. With a power rating of 5.5 kW for heavy-duty applications and a maximum power of 7.5 hp, this drive can handle substantial motor loads while maintaining efficiency and control. The power range of 5.5 to 7.5 kW and the adjustable switching frequency between 2 and 16 kHz (up to 4-16 kHz with a derating factor) add to its flexibility, allowing it to meet diverse motor control needs with minimal noise.

Advanced Motor Control and Precision Regulation

The ATV320U55N4B drive is designed to provide advanced control over synchronous and asynchronous motors, featuring vector control without sensors for synchronous motor applications. This control method enables precise torque and speed regulation, even without sensor feedback, making it ideal for open-loop applications. The drive’s output frequency ranges from 0.1 to 599 Hz, which enables users to tailor the motor’s speed to meet specific operational requirements. Its adjustable PID regulator further enhances control precision, allowing the drive to adjust motor operation dynamically based on the load and system feedback. It is beneficial in applications that require constant regulation.

Protection, Durability, and Cooling

With an IP20 protection rating in compliance with IEC 61800-5-1 and IEC 60529 standards, the ATV320U55N4B drive is designed to resist dust and minor particle ingress in controlled industrial environments. Schneider Electric’s reliable cooling system, equipped with a built-in fan, ensures that the drive maintains optimal operating temperatures, even under heavy-duty conditions. This cooling mechanism minimizes the risk of overheating and extends the drive’s lifespan, contributing to the durability and reliability that Schneider Electric is known for. A two-year warranty through MRO Electric and Supply and free shipping add peace of mind and value for customers.

Communication and Connectivity

To meet the requirements of modern industrial systems, the ATV320U55N4B is equipped with integrated Modbus serial and CANopen communication options, enabling seamless integration with various automation systems. These communication protocols allow for efficient data exchange, remote monitoring, and easy configuration, making the drive ideal for complex machine applications that require centralized control or real-time monitoring. The integrated Class C2 EMC filter ensures that the drive complies with electromagnetic compatibility standards, reducing interference with other equipment in the workspace.
