FAQ

The ATV900 series offers significant improvements, including enhanced energy efficiency, built-in Ethernet connectivity for IoT integration, advanced real-time intelligence, and more sophisticated motor control algorithms compared to the robust but older ATV71 technology.

No. The 'N4' suffix in the model number specifically indicates a three-phase input voltage range of 380-480V. Using it with a single-phase supply would damage the drive or cause it to fault.

The Altivar 71 natively supports CANopen and Modbus RTU protocols. Additional communication capabilities can be added via optional expansion cards, including protocols like EtherNet/IP, Modbus TCP, Profibus DP, and DeviceNet.
