Product Overview
The Schneider ATV71HD11N4 is a variable speed drive from the Altivar 71 series, specifically designed for complex, high-power machines. This robust drive offers 11 kW (15 HP) at 380...480 V three-phase, with an integrated EMC filter and a graphic terminal for easy configuration. Whether you are upgrading an existing system or installing new equipment, the ATV71HD11N4 provides reliable and precise motor control for both asynchronous and synchronous motors.
Standard Protection Features
Failures in industrial drives often stem from electrical faults, overheating, or mechanical stress. The Schneider ATV71HD11N4 addresses these common failure modes with comprehensive built-in protections. It guards against input phase loss, overvoltage, undervoltage, overcurrent, short-circuits, and overheating. Additionally, it includes thermal protection for both the drive and motor, as well as overload protection on the power supply. These features help minimize downtime and extend equipment life, making the ATV71HD11N4 a reliable choice for demanding applications.

Real-World Applications
The Schneider ATV71HD11N4 excels in applications that require precise speed and torque control. Common use cases include conveyors, pumps, fans, and compressors in manufacturing, water treatment, and HVAC systems. With its ability to handle both asynchronous and synchronous motors, it is also suitable for specialized machinery like extruders, mixers, and hoists. The integrated graphic terminal simplifies parameter adjustments for complex processes.
Installation and Setup
Mount the drive vertically within ±10 degrees to ensure proper cooling. Use shielded cable up to 164 ft (50 m) or unshielded up to 328 ft (100 m) for motor connections. The ATV71HD11N4 offers multiple wiring configurations: for control signals, use 2.5 mm² terminals; for power, use 16 mm² terminals. Tightening torques are 0.6 Nm for control and 3 Nm for power terminals. Ensure the power supply voltage is within 323...528 V and frequency between 47.5...63 Hz.
Troubleshooting Common Issues
If the drive trips on overvoltage, check the DC bus and braking resistor. For undervoltage faults, verify the line supply. Overcurrent alarms may indicate a short-circuit or motor phase loss. The LED indicator on the front panel provides diagnostic status. For advanced troubleshooting, the Modbus interface allows detailed parameter monitoring. Always consult the manual for specific fault codes.
Selection and Purchasing Guide
When ordering the Schneider ATV71HD11N4, verify that your motor power and voltage match the drive ratings. This model includes an integrated EMC filter and graphic terminal, but optional communication cards (e.g., Profibus DP, EtherNet/IP) are available for network integration. For fast delivery and genuine products, choose PLC Source PRO (formerly ubest101). Ensure you have the necessary cables and braking resistor if regenerative braking is required.
