Schneider Electric ATV71HD11N4

The Schneider Electric Altivar 71 Variable Speed Drive is designed for complex, high-power machines, offering superior performance and reliability. With a motor power of 11 kW and a maximum horsepower rating of 15 HP, this drive supports three-phase 380-480V power supply. It features an integrated EMC filter and a graphic terminal for easy monitoring and control.

This variable speed drive is suitable for both synchronous and asynchronous motors, providing advanced control profiles such as ENA (Energy adaptation) system for unbalanced loads, Sensorless flux vector control (SFVC), and Flux vector control (FVC) with sensor. The drive offers a wide output frequency range of 0.1 to 599 Hz and a nominal switching frequency of 4 kHz, adjustable up to 16 kHz with a derating factor.

Key benefits include precise speed and torque accuracy, with a speed range of 1-100 for asynchronous motors in open-loop mode and up to 1000 in closed-loop mode with encoder feedback. The drive ensures reliable performance with features like adjustable PI regulator, motor slip compensation, and transient overtorque capabilities.

Designed for easy integration, the Altivar 71 supports various mounting styles and electrical connections, including terminal connections for analog and discrete inputs/outputs. It also includes internal supplies for reference potentiometer and 24V DC with overload and short-circuit protection.

Applications include high-power industrial machines requiring precise motor control and...
