Product Overview

The Schneider ATV340U40N4E is a 4 kW, 5 HP high-performance variable speed drive from the Altivar Machine ATV340 range. It is designed for complex industrial machinery using a three-phase 380–480 VAC electrical supply.

The N4E suffix identifies the embedded-Ethernet version, providing Modbus TCP, EtherNet/IP and Modbus serial connectivity. This communication arrangement supports integration with industrial PLCs, machine controllers and Ethernet-based automation networks.

The drive is designed for dynamic machine applications requiring accurate motor control, high overload performance, rapid acceleration and controlled deceleration.

• Three-phase 380–480 VAC power supply
• Embedded Ethernet version
• Modbus TCP communication
• EtherNet/IP communication
• Modbus serial communication
• Integrated Safe Torque Off function
• Designed for demanding machine duty

Technical Specifications

Compatible System and Applications

The ATV340U40N4E is suitable for packaging machinery, conveyors, mixers, textile machines, hoisting equipment, material-handling systems, woodworking machinery and other high-performance production equipment.

It is particularly appropriate for Ethernet-connected machines requiring EtherNet/IP or Modbus TCP communication. Network compatibility must be reviewed against the installed PLC, switch topology and controller program.

Final sizing must consider motor current, motor technology, encoder type, overload torque, acceleration time, braking duty, switching frequency and ambient conditions.

Maintenance and Replacement Notes

Verify the complete ATV340U40N4E model. ATV340U40N4 is the Sercos-oriented counterpart and requires a different communication project.

Back up the original drive configuration before replacement. Record Ethernet addressing, motor parameters, I/O functions, safety settings, option-module data and braking parameters.

For used drives, inspect cooling fans, DC-bus capacitors, Ethernet connectors, power terminals, control terminals and fault history.

Related Models

ATV340U40N4 is the corresponding 4 kW Sercos III version. It is intended for a different controller-network architecture.

Adjacent N4E models include ATV340U30N4E at 3 kW, ATV340U55N4E at 5.5 kW and ATV340U75N4E at 7.5 kW.

Inquiry and Supply Notes

Please provide the complete original model, motor nameplate, controller model, communication protocol, IP configuration, braking duty and machine application.

Confirm firmware, encoder interface, option cards, safety requirements, product condition, test scope, availability and delivery time before quotation.
