Schneider Electric ATV31HU40N4 Overview

Powerful Motor Control Solution

The Schneider Electric ATV31HU40N4 Variable Speed Drive (VSD) stands as a powerful and versatile solution for controlling motors in applications that require variable speed control. Part of the Altivar ATV31 series, this VSD is meticulously engineered to optimize the performance of machines and processes, particularly in scenarios involving simple machines.

Robust Design for Industrial Environments

Designed with both robustness and advanced features in mind, the ATV31HU40N4 VSD is tailor-made for the demands of industrial environments. Its integrated Electromagnetic Compatibility (EMC) filter plays a pivotal role in minimizing electromagnetic interference, thereby contributing to stable and interference-free operations. This drive is carefully crafted to accommodate a supply voltage ranging from 380V to 500V, making it compatible with a wide spectrum of power systems.

Impressive Motor Power Capability

A standout feature of the ATV31HU40N4 is its impressive motor power capability. With a rated motor power of 4 kW (equivalent to approximately 5 horsepower), this VSD is primed to efficiently control motors operating within this power range. The motor control profile of the drive is founded on sensorless flux vector control, utilizing a pulse-width modulation (PWM) motor control signal. This profile comes factory-set to ensure consistent torque operation, rendering it an excellent fit for various industrial applications.

Precise Control and Monitoring Options

The VSD offers a multitude of analog input options (AI1, AI2, AI3), enabling precise control and monitoring capabilities. It caters to a range of input types, spanning voltage and current, thus ensuring seamless compatibility with an array of control signals. Complementing the analog inputs, the drive provides a comprehensive suite of discrete inputs (LI1...LI6) and outputs (R1A, R1B, R2A, R2B), offering versatile control configuration possibilities.

Comprehensive Protection Features

Protection features are integral to the longevity and safety of both the drive and the connected motor. The ATV31HU40N4 excels in this regard by providing comprehensive safeguards against various electrical faults. These include input phase breaks, line supply overvoltage, and undervoltage, motor phase breaks, overcurrent, overheating, and short-circuits between motor phases, among others. Such robust protection mechanisms effectively mitigate the risk of equipment damage and enhance overall operational safety.

User-Friendly Monitoring and Integration

Ease of use and monitoring are paramount, and the ATV31HU40N4 excels in this aspect. It boasts a 7-segment LED display that furnishes pertinent information about drive voltage and status, facilitating efficient monitoring. Additionally, the drive seamlessly integrates into control systems through diverse communication interfaces, including CANopen and Modbus via RJ45 connectors. This feature ensures effortless assimilation into larger automation setups.
