SIEMENS SIMOTION D445 6AU1445-0AA00-0AA0, high-performance multi-axis brushless controller

Built for demanding industrial environments, the SIEMENS SIMOTION D445, reference 6AU1445-0AA00-0AA0, is a brushless controller for multi-axis applications requiring accuracy, reliable synchronization and fast integration. It meets the needs of maintenance managers, system integrators and machine builders facing the complexity of driving brushless servomotors across multiple axes. By centralising trajectory computation and application logic, it optimises motion coordination, reduces drift risk and eases continuous operation. Its industrial connectivity, including DRIVE-CLiQ for direct interfacing with drives and actuators, plus PROFIBUS and Ethernet for communication with the PLC and the rest of the plant, enables controlled integration into automation architectures. 24 VDC power supply, 8 digital inputs and 8 digital channels configurable as input or output support structured commissioning and effective on-site diagnostics.

Productivity, reliability and control of brushless axes

• Precise multi-axis synchronization – The controller orchestrates motion profiles and coordination between brushless drives via DRIVE-CLiQ, ensuring consistent trajectories even at high cycle rates.
• Advanced industrial integration – PROFIBUS and Ethernet simplify data exchange with the PLC, HMIs and cell equipment for a smooth, traceable control chain.
• Streamlined commissioning – Integrated digital I/O and the SIMOTION architecture promote clear wiring, step-by-step testing and methodical validation, reducing downtime.
• On-site diagnostics – The 8 DI and 8 DI/DO channels ease status checks of sensors and actuators, giving immediate visibility on critical signals during adjustments and troubleshooting.
• Scalability and longevity – The SIMOTION platform allows machine growth, addition of brushless axes and software consistency, limiting modification costs.

Key technical features and build quality

The SIMOTION D445 is a SIEMENS motion controller designed for brushless axis control, with an architecture focused on precision and robustness. The DRIVE-CLiQ interface provides native connectivity to compatible drives and drive components, supporting a clear topology and homogeneous parameterisation. PROFIBUS and Ethernet links ensure reliable connectivity with existing automation infrastructure, whether supervision, HMI or cell controllers. The 24 VDC power supply simplifies cabinet integration and meets common control system standards. The 8 digital inputs, complemented by 8 digital channels configurable as input or output, offer immediate flexibility for managing sensors, limit switches, enable or fault signals. The industrial design, stemming from SIEMENS expertise, targets endurance in demanding production environments with attention to consistent performance and stable control in steady-state operation.
