Product Overview

The Schneider ATV340U75N4 is a 7.5 kW, 10 HP 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 dynamic industrial machinery.

The N4 suffix identifies the Sercos-oriented version, with integrated Sercos III and Modbus serial communication. The model is intended for coordinated machine systems where the drive must operate as part of an established Sercos controller project.

The drive can control compatible asynchronous, synchronous and permanent-magnet motors. Exact motor-feedback compatibility must be confirmed according to the installed motor, encoder and option configuration.

Technical Specifications

Compatible System and Applications

The ATV340U75N4 is suitable for dynamic conveyors, hoisting mechanisms, packaging lines, textile machinery, material-handling equipment, woodworking machines and coordinated production systems.

The Sercos III network, controller type, project version, device configuration and cycle requirements must be checked before replacement or commissioning.

For hoisting or high-inertia applications, braking energy, load profile, motor feedback, mechanical brake sequence and safety functions require detailed review.

Maintenance and Replacement Notes

ATV340U75N4 must not be replaced automatically by ATV340U75N4E. The N4E model uses embedded Ethernet communication rather than the Sercos-oriented architecture.

Record the Sercos project, firmware, motor data, encoder settings, safety wiring, braking parameters and I/O assignments before removing the installed drive.

Inspect the cooling system, power terminals, Sercos ports, DC-bus components, keypad and stored fault history on used equipment.

Related Models

ATV340U75N4E is the corresponding 7.5 kW embedded-Ethernet version with Modbus TCP and EtherNet/IP communication.

Adjacent Sercos models include ATV340U55N4 at 5.5 kW and ATV340D11N4 at 11 kW.

Inquiry and Supply Notes

Please provide the existing drive nameplate, controller model, Sercos configuration, motor data, feedback device, braking arrangement and machine application.

Firmware, option cards, safety functions, product condition, testing requirements, availability and delivery time must be confirmed before quotation.
