Key Features and Benefits

Energy Efficiency Optimization

The ATV630D55N4 integrates Schneider Electric’s EcoStruxure™ energy management technology, which automatically adjusts motor speed to match load demands—reducing energy consumption by up to 30% compared to fixed-speed drives. This feature is particularly valuable in applications like pumps, fans, and compressors, where variable load conditions are common, translating to long-term cost savings for users.

Robust Motor Protection

Equipped with comprehensive protection mechanisms, the ATV630D55N4 safeguards both the drive and connected motor against faults such as overcurrent, overvoltage, undervoltage, phase loss, and overtemperature. It also includes a built-in motor thermal protection function that eliminates the need for external thermal relays, simplifying system design and enhancing reliability.

Flexible Integration & Communication

The ATV630D55N4 supports a wide range of industrial communication protocols, including Modbus RTU, BACnet MS/TP, Ethernet/IP, and PROFINET. This allows seamless integration with PLCs, DCS systems, and building automation platforms, enabling centralized monitoring and control of multiple drives. Its plug-and-play compatibility with Schneider Electric’s TeSys™ motor control components further streamlines installation in new or retrofitted systems.

User-Friendly Operation & Diagnostics

The ATV630D55N4 features a large, backlit LCD display with intuitive navigation buttons, making it easy to configure parameters, monitor real-time data (e.g., current, voltage, speed), and troubleshoot issues. It also includes advanced diagnostic functions that log fault codes and operating trends, allowing maintenance teams to quickly identify and resolve problems—minimizing unplanned downtime.

Durability for Harsh Environments

Built with a rugged metal chassis and conformal-coated circuit boards, the ATV630D55N4 withstands dust, vibration, and temperature fluctuations in industrial settings. Its IP21 protection rating ensures safe operation in indoor environments where exposure to drips or light dust is possible, making it suitable for use in factories, warehouses, and water treatment facilities.
