SIMOTION D425-2 DP SIEMENS, multi-axis brushless controller for precise, high-speed motion

Designed for demanding industrial environments, the SIMOTION D425-2 DP is intended for maintenance teams, system integrators and machine builders seeking reliable brushless axis control and consistent responsiveness. This drive-based control unit manages up to 16 axes and delivers interpolation and servo cycles of 0.5 ms, enabling smooth trajectories, precise synchronization and stable productivity. Its extensive connectivity, with 4 DRIVE-CLiQ ports for drives, 2 PROFIBUS interfaces and 3 Ethernet ports, simplifies integration into new or existing architectures. The 24 V DC power supply, IP20 protection rating, plus the included dual fan module and backup battery, enhance service continuity. Compact and powerful, the SIMOTION D425-2 DP is a benchmark solution for confidently controlling your brushless axes in packaging, assembly, handling and general automation applications.

Productivity, precision and seamless integration

• High-speed synchronization – 0.5 ms interpolator and servo cycles, promoting trajectory accuracy and repeatability on brushless axes.
• Up to 16 controllable axes – Multi-axis capacity to scale your machines without multiplying controllers.
• Accelerated integration – 4 DRIVE-CLiQ connectors, 2 PROFIBUS and 3 Ethernet ports for direct connection to drives and factory networks.
• Improved availability – Dual fan module and backup battery included for operational continuity and simplified maintenance.
• Compact footprint – Size 380 x 50 x 270 mm for easy cabinet integration, IP20 suitable for automation environments.

Reliable, scalable technical architecture

The SIMOTION D425-2 DP belongs to the BASIC performance class, suited to a wide range of motion applications. It offers integrated control of 6 servo axes, 6 vector axes, or 12 V/f axes to optimize the match between kinematics and process requirements. The platform communicates with drives via 4 DRIVE-CLiQ ports and interfaces with the field via 2 PROFIBUS links, with a minimum cycle time down to 1 ms to ensure deterministic exchanges. The presence of 3 Ethernet ports and 2 USB ports simplifies engineering, supervision and maintenance. On the signal side, the unit integrates 12 digital inputs as well as 16 digital I/O channels for auxiliary functions and peripheral safety, depending on the chosen architecture. The 24 V DC supply accepts 20.4 to 28.8 V for compatibility with cabinet standards. The IP20 enclosure, complemented by a dual fan module and backup battery, strengthens operational robustness. The fast interpolator and servo cycles, both at 0.5 ms, support production rates while stabilizing trajectory quality on brushless motors. An optional slot is available for targeted expansions if needed.

Typical uses and operating contexts

The D425-2 DP is suitable for packaging, assembly and handling machines, as well as light robotic systems that require precise brushless axis control. Engineering departments use it for compact multi-axis architectures, while maintenance teams appreciate its straightforward implementation and versatile communications. In retrofit as well as new-build projects, it increases axis density without complicating the cabinet.
