6AU1435-0AA00-0AA1 - Motion control system - SIEMENS

SIMOTION D435 6AU1435-0AA00-0AA1, the precise, scalable brushless controller for your axes

Designed for industrial environments where production continuity and trajectory repeatability are critical, the SIMOTION D435 from SIEMENS provides a robust control platform for brushless motors and servo motors. This drive-based motion controller consolidates logic, interpolation and axis synchronization close to the drive to reduce latency and optimise machine dynamics. It controls up to 32 axes in total and natively supports control for 6 servo axes, 4 vector axes and 8 V/f axes, covering a wide range of applications from precise positioning to coordinated high-speed motion. DRIVE-CLiQ, PROFINET and PROFIBUS interfaces accelerate integration into existing automation architectures, while minimum cycle times of 0.5 to 1 ms ensure consistent responsiveness. For methods, maintenance and integration teams, it is a pragmatic, stable and well-documented solution sized for series production as well as high-variability lines.

Axis performance, repeatability and operational availability

• Stable multi-axis synchronization – The interpolator and 1 ms servo control guarantee coherent trajectories and smooth transitions for brushless motors.
• Scalable up to 32 axes – The platform supports progressive machine expansion without heavy requalification of the architecture.
• Accelerated integration – 4 DRIVE-CLiQ ports and standard industrial buses reduce engineering and commissioning time.
• Short cycle times – PROFINET at 0.5 ms and PROFIBUS at 1 ms help maintain throughput and precision at high speed.
• Operational reliability – cULus and RCM certified design, operating temperature range 0 to 55 °C and IP20 rating suitable for industrial workshops.

Controlled architecture and technical specifications

The SIMOTION D435, reference 6AU1435-0AA00-0AA1, offers comprehensive connectivity with 4 DRIVE-CLiQ interfaces, 2 Industrial Ethernet ports, 2 PROFIBUS interfaces, 2 USB ports, as well as 8 digital inputs and 8 channels configurable as digital inputs/outputs. For processing it provides 48 MB of working RAM, 20 MB dedicated to Java, 29 MB of RAM disk, 364 KB of retention memory and 300 MB of persistent memory, ensuring storage of projects and machine parameters. Power is 24 V DC with a nominal current of approximately 600 mA and a typical power loss of 15 W. On the dynamics side, minimum cycle times are 1 ms for the interpolator and servo loop, 0.5 ms on PROFINET and 1 ms on PROFIBUS. The compact form factor fits in a cabinet with dimensions of 380 x 50 x 270 mm. The operating temperature range is 0 to 55 °C, storage -40 to 70 °C, degree of protection IP20. cULus and RCM certifications attest to compliance with safety and compatibility requirements.
