These specs show the Schneider ATV71HD15N4 provides robust performance and protection for high-torque applications, reducing downtime and maintenance costs.
Installation & Setup Guidance
For optimal performance, mount the Schneider ATV71HD15N4 vertically (within ±10°). Use shielded motor cables up to 50 m or unshielded up to 100 m. The drive accepts 3-phase supply via terminals rated for 35 mm² (AWG 2). Ensure proper tightening torque: 5.3 lbf·in for control terminals and 47.8 lbf·in for power terminals. The unit includes a built-in heatsink; maintain adequate airflow. For enclosure installation, use NEMA Type 1, IP21, or IP31 kits as specified in the datasheet from the manufacturer.
Compatibility & Integration
The Schneider ATV71HD15N4 supports Modbus (RS-485) and CANopen communication protocols natively, with RJ45 connectors on the front face and terminal. It can connect to a wide range of automation networks via optional communication cards (DeviceNet, EtherNet/IP, Profibus DP, Modbus TCP, and more). An encoder interface card enables closed-loop flux vector control for precise speed and torque regulation. This flexibility allows the Schneider ATV71HD15N4 to integrate seamlessly into existing control systems, improving overall system efficiency.
Selection Guide & Purchasing Advice
Before purchasing the Schneider ATV71HD15N4, confirm your motor power rating (15 kW/20 hp) and supply voltage (380–480 V, 3-phase). Verify mounting space: the unit measures 15.7 in high, 9.06 in wide, and 8.4 in deep, with a net weight of 28.7 lb. For complex applications requiring additional I/O or fieldbus interfaces, consider ordering the required option cards separately.
