The Schneider Variable Speed Drive ATV71HD11N4 is an 11 kW variable speed drive engineered for sophisticated motor control applications, supporting both asynchronous and synchronous three-phase motors. It operates within a wide power supply range from 323V to 528V, with a frequency tolerance of 47.5 to 63 Hz, ensuring compatibility with various global power standards and stable performance despite voltage fluctuations. This flexibility makes the drive suitable for diverse industrial environments where power conditions may vary.

A key strength of the Schneider Variable Speed Drive ATV71HD11N4 lies in its advanced control capabilities. It offers multiple control profiles including Sensorless Flux Vector Control (SFVC) for high-performance operation without an encoder and precise Flux Vector Control (FVC) with encoder feedback for closed-loop applications. The drive also features configurable voltage/frequency ratios and an ENA (Energy Adaptation) system that automatically compensates for unbalanced loads, enhancing motor stability and efficiency across different operating conditions.

The performance specifications of the Variable Speed Drive ATV71HD11N4 are particularly impressive, especially in closed-loop configuration where it achieves a speed range of 1:1000 with exceptional accuracy of ±0.01% of the nominal speed. Even in open-loop mode, it maintains a respectable 1:100 speed range for asynchronous motors. This level of precision ensures reliable operation in demanding processes where consistent speed maintenance is critical, from conveyor systems to precision machining applications.

Designed for seamless integration into industrial networks, the Drive ATV71HD11N4  Schneider includes Modbus communication capability while operating without impedance polarization. The versatility of the SCHNEIDER ATV71HD11N4 makes it an ideal solution for applications requiring both high dynamic performance and energy efficiency, effectively reducing mechanical stress on driven equipment while optimizing power consumption in continuous operation scenarios.
