Product Overview
The Schneider ATV340U22N4 is a 2.2 kW, 3 HP high-performance Altivar Machine ATV340 variable speed drive for three-phase 380–480 VAC industrial power systems.
The N4 suffix identifies the Sercos-oriented communication version. It supports Sercos III and Modbus serial communication and is intended for machine-control systems requiring coordinated communication between a controller, drive and other motion components.
The ATV340U22N4 is suitable for high-dynamic machine applications requiring rapid response, accurate speed or torque regulation and reliable integration into an existing Sercos automation project.

Compatible System and Applications
The ATV340U22N4 is suitable for machinery using a Sercos III controller network. Typical applications include packaging systems, coordinated conveyors, material-handling equipment, hoisting machines, textile equipment and automated manufacturing lines.
The controller model, Sercos topology, cycle time, device addressing, axis configuration and machine project must be checked before using this drive as a replacement.
Motor selection must also consider rated current, feedback device, acceleration profile, overload torque, braking requirements and operating environment.
Maintenance and Replacement Notes
Do not treat ATV340U22N4 and ATV340U22N4E as interchangeable. Although both have the same nominal power and supply class, their integrated communication architectures are different.
Before replacement, back up or record the Sercos configuration, drive parameters, firmware, motor data, I/O assignments, safety wiring and installed option modules.
Inspect the Sercos ports, cooling system, power terminals, DC-bus components, control terminals and stored fault history when evaluating a used unit.
Related Models
ATV340U22N4E is the corresponding 2.2 kW embedded-Ethernet version with Modbus TCP and EtherNet/IP communication.
Adjacent Sercos versions include ATV340U15N4 at 1.5 kW, ATV340U30N4 at 3 kW and ATV340U40N4 at 4 kW.
Inquiry and Supply Notes
Please provide the original drive model, controller model, Sercos project information, motor nameplate, encoder type, supply voltage and machine application.
Firmware, option modules, safety functions, braking configuration, product condition, functional testing, availability and delivery time must be confirmed before quotation.
