Compatible System and Applications
The ATV340D11N4 is suitable for Sercos-based conveyors, hoisting systems, packaging machinery, material-handling equipment, textile machinery and coordinated production lines.
The Sercos master, topology, cycle time, project configuration, device addressing and firmware must be checked before replacement.
Maintenance and Replacement Notes
ATV340D11N4 must not automatically be replaced by ATV340D11N4E. Although the power and voltage classes are similar, the communication architectures are different.
Back up the Sercos project, drive parameters, motor data, encoder settings, safety wiring and installed option modules before removing the original drive.
Inspect cooling fans, power terminals, Sercos ports, DC-bus components and stored fault history when evaluating used equipment.
