Robotics Safety Architecture. Ready for 2028!
Open safety architecture for the next generation of robotics
New requirements under ISO 10218:2025, increasing complexity in HRC (human-robot collaboration) applications, and proprietary safety solutions present new challenges for machine builders, robotics OEMs, and integrators. Today, safety must be considered early on in architectural decisions—because later adjustments result in high engineering costs, long integration times, and limited scalability.
To address precisely these challenges, Kendrion combines its SIL3/PLe safety controller with a safety library that includes kinematic functions for robot applications. The open safety architecture enables vendor-neutral integration into EtherCAT- and FSoE-based robotics systems and reduces dependence on proprietary robot platforms.
With an integrated safety library for motion, force, and spatial zone monitoring, a minimum cycle time of 2 ms, and support for up to 9 axes, Kendrion lays the foundation for flexible, scalable, and standards-compliant robotic safety concepts up to SIL 3 / PLe.
The Kendrion safety architecture enables the seamless integration of modern robotic safety functions into existing EtherCAT and FSoE networks. The EtherCAT master communicates directly with the safe FSoE servo drives via the Kendrion safety PLC, providing end-to-end safety communication for robots with up to 9 axes.
The Safety PLC handles the kinematic safety monitoring of the entire robot movement and processes safety-relevant data from all integrated axes and drives in real time with a minimal cycle time of 2 ms. Movements, speeds, forces, as well as spatial and distance zones are continuously monitored—regardless of the robot system or drive manufacturer used.
Thanks to the open and scalable architecture, existing automation, motion control, and servo drive concepts can be flexibly reused and efficiently expanded with modern safety functions — without the need for proprietary robotic controllers.
Cobots – Fast, Safe, and without Enclosures
In practice, the use of cobots often fails due to safety requirements: Either the speed is significantly reduced to comply with permissible force limits, or the cobot is spatially enclosed—just like a traditional industrial robot. Both approaches hinder efficient human-robot collaboration.
Kendrion offers a powerful alternative here. With scalable safety controllers and application-specific safety libraries, cobots can be dynamically controlled—for maximum productivity while maintaining the highest level of safety. This ensures that collaboration between humans and machines remains fast, flexible, and compliant with standards.
Even with traditional industrial robots — for example, during the teach-in or service phase — stricter safety requirements can be reliably met. Solutions designed to meet the requirements effective from 2028 will be available shortly.
Get ready for 2028 with the Kendrion Safety Architecture for robot kinematics!
The new ISO 10218:2025 standard expands the safety approach from the traditional protection of individual robot movements to a holistic view of the entire robot application. Dynamic safety zones, context-dependent safety responses, and advanced functions for human-robot collaboration and safe force monitoring are becoming the new standard.
Our Kendrion Safety PLC with an integrated safety library supports this shift with powerful safety functions at the application level. Advanced safe space monitoring, adaptive safety logic, and model-based, safe force and power limiting enable flexible, efficient, and simultaneously standards-compliant automation solutions. In this way, we lay the foundation for safe, intelligent, and future-proof robotics applications.

Complex Real-Time Kinematic Calculations
The Kendrion Safety Architecture for robotics combines high-performance kinematic calculations with precise real-time processing for modern robotic systems. Even complex robot kinematics with up to 9 axes, up to 20 safety zones, and dynamic safety functions are processed reliably and deterministically.
The scalable safety architecture enables ultra-fast calculations of movements, speeds, positions, and external forces at the link level. At the same time, flexible 3D safety zones as well as in- and out-of-zone areas are continuously monitored in real time.
Thanks to its powerful computational architecture, the Kendrion solution is ideally suited for demanding robotics applications with high requirements for dynamics, precision, and functional safety.
