Siemens 6AU1445-0AA00-0AA1 SIMOTION D445-1 Motion Controller
01Technical Summary
Siemens 6AU1445-0AA00-0AA1 is a SIMOTION D445-1 programmable motion controller in the high-performance class. It is a legacy spare-part article for machines combining PLC, motion, and SINAMICS drive-control tasks. Siemens identifies this article as discontinued and deleted without a stated direct replacement, so procurement and migration must be controlled against the installed project.
02Applications
Typical Uses
- High-performance multi-axis machines originally engineered around the SIMOTION D445-1 platform.
- Coordinated positioning, gearing, camming, interpolation, and technology control with SINAMICS drives.
- PROFIBUS-based distributed automation combined with DRIVE-CLiQ drive topology.
- Legacy spare-part replacement where the exact controller revision, memory card, software, and project are retained.
- Lifecycle planning for machines that cannot yet be migrated to a current automation 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.

- Lifecycle: Product Discontinued
05Compatibility
- Match the complete 6AU1445-0AA00-0AA1 article and do not collapse it with a D445-2, D455, or another hardware revision.
- Confirm the controller firmware, SIMOTION software release, CompactFlash card, licenses, technology packages, and option board.
- Preserve PROFIBUS addresses, Industrial Ethernet settings, telegrams, DRIVE-CLiQ topology, and drive firmware.
- Verify the dual fan/battery module, 24 V supply, connector keying, grounding, shielding, and cabinet cooling.
- Because Siemens states no replacement for this article, any platform change must be treated as a full engineered migration.
- Validate obsolete option modules and field devices separately because a controller-only comparison does not prove system compatibility.
06Maintenance & Replacement
- Create verified backups of the project, card contents, licenses, drive parameters, safety data, and commissioning records.
- Record hardware and firmware versions, option board, axis and drive assignments, fieldbus settings, I/O wiring, and machine-specific technology parameters.
- Inspect the fan/battery module and keep a controlled record of battery replacement and cabinet thermal condition.
- After exchange, verify startup, memory-card recognition, project consistency, communication, axes, encoders, limits, alarms, interlocks, and safety functions.
- Run reference, low-speed, synchronized-motion, and controlled production tests before release.
- Maintain a migration plan because the official lifecycle record identifies the article as discontinued without replacement.
FAQFrequently Asked Questions
What is 6AU1445-0AA00-0AA1?
6AU1445-0AA00-0AA1 is a discontinued high-performance SIMOTION D445-1 programmable motion controller for legacy multi-axis machines.
Where is this product normally used?
It is used in machines combining high-performance motion control, PLC logic, and SINAMICS drive coordination.
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, option module, fieldbus settings, drive topology, axes, I/O, safety records, and validated commissioning data.
Can a similar Siemens article be used as a direct replacement?
No direct replacement is stated by Siemens. A different SIMOTION or automation controller requires an engineered migration and complete machine validation.
What should be verified after installation?
Verify project and card recognition, communication, all axes, encoders, brakes, limits, I/O, alarms, interlocks, safety functions, and the full machine process.
