Product features

Schneider ATV71HD30N4 is a high-performance variable speed drive from Schneider Electric's Altivar 71 series, designed for industrial motor control. This 30 kW (40 HP) inverter runs on a three-phase voltage range of 380 to 480 volts AC, making it compatible with the majority of common industrial power systems. It employs innovative flux vector control technology, which can operate with or without a sensor to provide steady and precise speed regulation-its speed range is 1:1000 in closed-loop mode with an encoder and 1:100 in open-loop mode. This makes the Schneider ATV71HD30N4 perfect for applications requiring precise speed control, such as conveyor belts, mixers, pumps, and fans.

The Schneider ATV71HD30N4 has several built-in functions. It protects both the motor and the drive by providing overcurrent, overvoltage, undervoltage, and short-circuit protection. It can work reliably in temperatures ranging from -10°C to 50°C and be kept at -25°C to 70°C, making it suitable for a variety of industrial situations. With an IP20 protection rating, it is appropriate for panel or wall mounting in indoor industrial environments.

Connectivity is another benefit of the Schneider ATV71HD30N4. It has Modbus and CANopen communication protocols and supports additional connection cards like Ethernet, PROFIBUS DP, and DeviceNet for seamless integration into various industrial control systems. It also includes I/O expansion options and an encoder interface board, enabling users to tailor the drive to their exact requirements. Optional brake resistors can be added to improve braking torque by up to 150%, making it even more useful for cranes and hoists.

Application scenarios

One important application for the Schneider ATV71HD30N4 is in industrial pump and fan systems. Many factories, water treatment plants, and HVAC facilities rely on pumps and fans to circulate fluids or air, and this VFD's built-in PID controller and energy-saving features help to maximize operation. It modifies motor speed in response to real-time demand, such as slowing down a water pump when tank levels are high or a fan when temperature requirements are met. This not only saves energy but also decreases equipment wear, since the Schneider ATV71HD30N4's 170% rated torque capacity handles start-up loads easily and without straining the motor. Its built-in Class A EMC filter also protects against electromagnetic interference, ensuring trouble-free operation alongside other plant equipment.

The Schneider ATV71HD30N4 is also suitable for conveyor systems in factories, warehouses, and distribution centers. Conveyors frequently require precise speed control to match manufacturing lines or avoid product damage, and this drive offers a 1:1000 speed range in closed-loop mode (by encoder). Whether moving big boxes, assembly parts, or bulk items, the Schneider ATV71HD30N4's flux vector control maintains speed even under fluctuating loads. Its short-circuit and overcurrent protection mechanisms protect the conveyor motor and drive from mishaps, reducing downtime. Furthermore, built-in Modbus and CANopen connectivity allow it to interact easily with factory control systems, making it simple to monitor and alter conveyor speed remotely.

FAQ

Q: What is the Schneider Electric ATV71HD30N4?

A: Schneider Electric's ATV71 series includes the ATV71HD30N4, a high-performance three-phase asynchronous and synchronous motor drive. It is intended for demanding industrial applications that necessitate accurate speed and torque control. The "HD30N4" in the model number normally refers to a drive with a power rating of 30 kW (about 40 HP) and is designed for a 380-480 V AC three-phase power supply.
