Description

The KEBA CU313/B-SI/58626/09​ is a high-performance, modular servo drive and control unit from KEBA’s KeDrive D3 series, designed for precise and dynamic motion control in advanced industrial automation applications . This all-in-one control system combines controller functionality with optional integrated safety technology in a compact, gapless form factor, making it ideal for applications ranging from simple PLC tasks to complex multi-robot systems and machine tools . The “B-SI” designation indicates enhanced safety integration capabilities, while the specific variant number “58626/09” represents a particular configuration within the CU313 product family.

Application Scenarios

In a high-speed packaging line for pharmaceutical products, precision and reliability are paramount. The line requires synchronized control of multiple servo axes for filling, capping, labeling, and packaging operations, all while maintaining strict safety standards to protect both operators and products.

The KEBA CU313/B-SI/58626/09​ was implemented as the central control unit, managing eight servo axes through its integrated EtherCAT master interface. Its real-time processing capabilities ensured precise coordination between the filling nozzles and conveyor belts, reducing product waste by 18%. The integrated safety controller (SI) enabled Safe Torque Off (STO) and Safe Limited Speed (SLS) functions directly at the drive level, eliminating the need for external safety relays and simplifying cabinet design. During a routine safety check, the system detected an abnormal torque reading on one axis and initiated a controlled stop within milliseconds, preventing potential equipment damage. The plant manager noted, “The CU313/B-SI not only improved our packaging speed by 25% but also gave us peace of mind with its built-in safety features.”

Technical Principles and Innovative Values

Innovation Point 1: All-in-One Control Architecture – The KEBA CU313/B-SI/58626/09​ integrates motion controller, drive amplifier, and safety controller into a single compact unit, eliminating the need for separate components and reducing system complexity . This integrated approach minimizes wiring, saves cabinet space, and improves system reliability by reducing connection points.

Innovation Point 2: Modular Scalability with Axis Expansion – The D3 controller design allows flexible connection of 1. 2. or 3 axis controllers on the right side, enabling scalable solutions from simple single-axis applications to complex multi-robot systems . This modularity provides cost-effective expansion options as production requirements grow.

Innovation Point 3: Integrated Safety Technology – The “SI” (Safety Integrated) variant includes a freely programmable safety controller with safe inputs and outputs onboard, enabling implementation of Safe PLC, Safe Motion, and Safe Robotics applications without additional hardware . This integrated safety approach simplifies compliance with machine safety standards like ISO 13849 and IEC 62061.

Innovation Point 4: High-Performance Real-Time Processing – With processor options ranging from Intel Atom Quad Core 1.9 GHz to Intel Celeron 2 GHz, the controller delivers application-optimized computing power for visualization, image processing, PLC, motion, robotics, and CNC functions on a single platform . This eliminates the need for separate visualization computers or additional processing units.

Application Cases and Industry Value

A automotive parts manufacturer implemented KEBA CU313/B-SI/58626/09​ controllers in their robotic welding cells for chassis assembly. Each cell required precise coordination between six-axis robots, positioners, and welding equipment, with strict safety requirements for human-robot collaboration areas.

The previous system used separate motion controllers, drives, and safety relays, resulting in complex wiring and frequent synchronization issues. After upgrading to the CU313/B-SI units, the manufacturer achieved 30% faster cycle times due to the improved real-time communication between axes. The integrated safety functions allowed for dynamic safety zones that adjusted based on robot position, enabling closer human-robot collaboration during maintenance without compromising safety. The production engineering manager reported, “The KEBA system reduced our commissioning time by 40% and eliminated the synchronization problems we had with our previous setup. The built-in safety features also simplified our risk assessment documentation.”
