Siemens 6AU1435-2AA00-0AA0 SIMOTION D435-2 DP Motion Controller
01Technical Summary
Siemens 6AU1435-2AA00-0AA0 is the SIMOTION D435-2 DP programmable motion controller in the standard-performance class. It combines motion control, PLC, and technology functions with an integrated SINAMICS drive-control platform. This DP version provides two PROFIBUS interfaces and does not include the onboard three-port PROFINET interface found on the DP/PN article.
02Applications
Typical Uses
- Coordinated multi-axis machine automation requiring motion control and standard PLC logic in one controller.
- Machines using PROFIBUS DP for distributed I/O, drives, or higher-level automation communication.
- SINAMICS S120 drive systems connected through the integrated DRIVE-CLiQ interfaces.
- Electronic gearing, camming, positioning, synchronous operation, and technology-object applications.
- Like-for-like maintenance of an installed D435-2 DP hardware and software architecture.
Selection Boundary
- Use application examples only as engineering context; they do not prove compatibility with an installed machine.
- Confirm electrical, mechanical, network, software, safety, environmental, and lifecycle requirements against the complete project.
- Preserve configuration records and perform controlled commissioning whenever hardware is exchanged.

04Features
Design and Functions
- Standard-performance SIMOTION D platform rated for configurations with up to 32 axes.
- Integrated drive control supports up to six servo axes, six vector axes, or twelve V/f axes within the documented drive limits.
- Minimum documented PROFIBUS cycle is 1 ms; minimum servo and interpolator cycle is 0.5 ms.
- Two PROFIBUS, three Industrial Ethernet, two USB, and six DRIVE-CLiQ interfaces support machine-level integration.
- Twelve digital inputs and sixteen configurable digital input/output channels are available for local signals.
- The order record includes the dual fan/battery module and battery; the required CompactFlash card and project remain configuration items.

05Compatibility
- Use this DP article where the project and cabinet are engineered for PROFIBUS; do not assume the DP/PN article is wiring- or project-identical.
- Confirm SIMOTION SCOUT or SCOUT TIA software release, controller firmware, CompactFlash card, licenses, technology packages, and project archive.
- Match the SINAMICS topology, DRIVE-CLiQ node sequence, drive firmware, motor and encoder data, and safety design.
- Preserve PROFIBUS addresses, bus parameters, termination, telegrams, diagnostics, and higher-level controller links.
- Check the fan/battery module, option board, memory card, connectors, shielding, grounding, and 24 V supply before exchange.
- A controller with higher performance or a different communication variant still requires an engineered migration and project conversion.
06Maintenance & Replacement
- Create a complete SCOUT or SCOUT TIA project archive and save the CompactFlash card contents before removing the controller.
- Record article number, hardware and firmware versions, licenses, axis assignments, drive topology, PROFIBUS addresses, Ethernet settings, I/O wiring, and option modules.
- Inspect fan operation, battery condition, memory card seating, connector locking, shielding, cabinet cooling, and supply quality.
- After replacement, verify controller startup, project consistency, axis enables, encoder feedback, homing, limits, synchronization, PROFIBUS communication, diagnostics, alarms, and safety functions.
- Run the machine through a controlled commissioning sequence before returning it to automatic production.
- For lifecycle planning, evaluate a supported SIMOTION or alternative Siemens architecture as a project migration rather than a direct article-number swap.
FAQFrequently Asked Questions
What is 6AU1435-2AA00-0AA0?
6AU1435-2AA00-0AA0 is a standard-performance SIMOTION D435-2 DP programmable motion controller with integrated SINAMICS drive control.
Where is this product normally used?
It is used in coordinated motion machines that use PROFIBUS communication and DRIVE-CLiQ-connected SINAMICS components.
What must be checked before ordering?
Confirm the complete article number, installed hardware revision, lifecycle state, supply and I/O design, communication interfaces, connector assignment, software release, approvals, and project configuration.
What information should be saved before replacement?
Save the complete project and card image, licenses, firmware, axis and drive topology, addresses, telegrams, I/O wiring, option modules, safety data, and commissioning records.
Can a similar Siemens article be used as a direct replacement?
No. The DP/PN model and newer controllers differ in communication hardware, firmware, memory, software support, and project requirements, so Siemens-supported migration checks are required.
What should be verified after installation?
Verify project loading, topology, every axis, encoders, brakes, limits, I/O, PROFIBUS, Ethernet service access, alarms, interlocks, safety functions, and the full machine cycle.
