Schneider ATV340U55N4E ATV340 5.5kW Embedded Ethernet Variable Speed Drive
Product Overview
The Schneider ATV340U55N4E is a 5.5 kW high-performance variable speed drive from the Altivar Machine ATV340 series. It operates from a three-phase 380–480 VAC supply and is designed for demanding industrial machinery.
The N4E suffix identifies the embedded-Ethernet version, supporting Modbus TCP, EtherNet/IP and Modbus serial communication. This makes the drive suitable for machines integrated with industrial PLC and Ethernet control systems.
The drive is intended for applications requiring fast acceleration, controlled deceleration, high overload capability and accurate motor-speed or torque regulation.

Maintenance and Replacement Notes
Verify the complete ATV340U55N4E reference. The corresponding ATV340U55N4 model uses a different Sercos-oriented communication architecture.
Back up motor parameters, network addresses, I/O functions, safety settings, acceleration profiles and firmware information before replacing the original drive.
For used products, inspect cooling components, power terminals, DC-bus components, Ethernet ports and stored fault records.
