SIMOTION D445-2 DP/PN 6AU1445-2AD00-0AA0, high-performance multi-axis brushless controller

For maintenance teams and system integrators who need stable trajectories and high throughput with brushless servomotors, the SIMOTION D445-2 DP/PN provides deterministic motion control and a drive-oriented architecture. This drive-based control unit concentrates computation close to the drives, reducing latency, improving motion profile accuracy and simplifying the control cabinet. Designed to coordinate multi-axis groups, it supports up to 128 axes depending on configuration. DP/PN buses, DRIVE-CLiQ links and integrated I/O speed up integration, commissioning and maintenance. Beyond performance, its Booksize format makes it easy to install in space-constrained environments. In case of failure or obsolescence, Standard Exchange Industry offers this brushless controller as a standard exchange unit, new or refurbished, with 24 to 72-hour lead times to secure your restart.

Motion control and production continuity

• Reliable multi-axis synchronization – Coordinated control of brushless servomotors for precise, repeatable profiles, even in high-throughput applications.
• Faster commissioning – Built-in DP/PN, DRIVE-CLiQ and I/O interfaces reduce wiring, simplify axis auto-detection and minimise downtime.
• Proven scalability – Expandable up to 128 axes depending on topology, supporting increased throughput and added stations without redesigning the architecture.
• Structured diagnostics – Clear status messages and link monitoring that simplify root-cause analysis and support preventive maintenance.
• Compact footprint – Booksize format and drive-proximate control save control cabinet space and optimise thermal management.

Architecture, interfaces and design quality

The SIMOTION D445-2 DP/PN is a drive-based motion control unit from the D4x5-2 range. Its design moves computation closer to the drives to execute regulation and motion functions at the drive level. The device supports multi-axis coordination and provides control capabilities for up to 128 axes depending on sizing. On the communication side, it includes DRIVE-CLiQ links for connection to compatible drives and sensors, as well as DP/PN buses for deterministic data exchange with the rest of the machine. Digital inputs and mixed DI/DO points are available to handle control signals and machine states, complemented by USB ports for backup and maintenance. Offered in Booksize format, the unit enables compact integration into automation cabinets. Engineering choices prioritise link robustness, clarity of diagnostics and timing stability of motion sequences—key criteria for meeting tolerances and maintaining cycle times in industrial environments.

Applications and environments

This brushless controller is used in assembly, packaging and handling machines and in any application requiring precise multi-axis coordination with brushless servomotors. It is aimed at operators who need to secure an existing line, integrators modernising obsolete machines, and design offices seeking deterministic control for complex motion profiles. Its DP/PN and DRIVE-CLiQ connectivity facilitates interfacing with drives and the machine control layer.

Differentiation, reliability and service

Backed by SIEMENS expertise in motion control, the D445-2 DP/PN stands out for its drive-based execution that reduces latency and for streamlined integration via DRIVE-CLiQ. Standard Exchange Industry reinforces this reliability with test processes, full traceability of interventions and solutions adapted to production emergencies. Depending on the selected service, you benefit from a 6 to 24-month warranty. International availability, 24–72-hour shipping and technical support aim to reduce the risk of extended downtime and secure the restart of your installations.
