Product Overview
The Schneider ATV340U75N4E Variable Speed Drive is a high-performance AC Variable Frequency Drive (VFD) from the Altivar Machine ATV340 series, specifically developed for advanced industrial automation systems that require intelligent motor control, rapid dynamic response, and reliable long-term operation. Designed for OEM machine builders, automation integrators, and industrial manufacturers, the ATV340U75N4E combines Schneider Electric’s advanced vector control technology with embedded Industrial Ethernet communication, enabling seamless integration into modern Industry 4.0 production environments.
Rated for 7.5 kW heavy-duty applications, the drive provides highly accurate control of both three-phase asynchronous induction motors and permanent magnet synchronous motors. Its advanced digital control platform delivers excellent low-speed torque, precise speed regulation, fast acceleration and deceleration, and stable performance under varying load conditions. These capabilities make the drive particularly suitable for demanding machinery where productivity, repeatability, and motion precision are essential.
The integrated Industrial Ethernet interface allows direct communication with Schneider Modicon PLCs, Human Machine Interfaces (HMIs), SCADA platforms, industrial PCs, and Ethernet-based automation networks. Engineers can remotely configure parameters, monitor operating conditions, perform diagnostics, and implement predictive maintenance strategies without requiring additional communication modules.
Comprehensive protection functions—including overload protection, motor thermal protection, overvoltage protection, undervoltage protection, phase-loss monitoring, overtemperature protection, short-circuit protection, motor stall detection, and integrated Safe Torque Off (STO)—help ensure maximum equipment reliability while improving personnel safety and reducing maintenance requirements.
With compact dimensions of 110 × 270 × 234 mm and an approximate weight of 3.0 kg, the ATV340U75N4E offers an excellent combination of high power density and space-saving installation, making it ideal for modern industrial control cabinets.
