Safety technology included

KeSafe D3 is the solution for safety technology for robots and machines. It is offered in combination with the compact control and drive system KeDrive for Motion. The integrated safety board guarantees safe operation of machines and robots in accordance with current standards and regulations.
Safety applications are created easily and efficiently with the certified functional modules. Our integrated solution enables optimal co-operation of functional and safe applications (assistant systems).

The safe communication between the individual safety components takes place via FSoE (Fail Safe over EtherCAT). The safe data transfer to the superordinate or subordinate safety systems is supported by several interfaces:

FSoE master/slave via EtherCAT
PROFIsafe slave for F-Device via PROFINET

The freely programmable safety application can be created easily using the application tool KeStudio SafeEdit that is integrated into KeStudio. Additionally, the tool allows for easy diagnosis and validation of the safety application.

Available in three configuration levels

The functionalities of our safety technology KeSafe D3 covers simple logical links and safe single-axis functions as well as extended safety functions for robotics applications.

Safe logic applications

KeSafe D3 PLC

Pre-constructed components are used to build standard safety elements such as emergency stop switches, enabling switches etc. and are combined to create a complete safety application. Selectable logic modules enable the creation of fully customized KeStudio links between input states and actuators, which can be safely controlled via safe digital outputs.
Driver-specific safety functions such as STO (Safe Torque Off) and SBC (Safe Brake Control) are implemented in the same way.

Benefits:

Certified functional modules for easy integration of common safety elements
Freely programmable by linking secure input modules with safe output modules using standard logic modules
Safe onboard I/Os and additional safe I/O modules can be controlled in a decentralized form via the FSoE master

Safe single-axis applications

KeSafe D3 Motion

Safe functionalities for single-axis monitoring can be realized with the KeSafe D3 safety controls. KeStudio offers an individual module for each safety function that can then be integrated into the safety application. This allows for the representation of any safe machine functionalities on single-axis basis.

Benefits:

Manifold certified safety functionalities to monitor single-axis in accordance with EN 61800-5-2
No limits of combinations of KeSafe D3 PLC functionalities
Requirement: KeDrive encoder box and drive units with safe Hiperface-DSL encoders

Safe robotics applications

KeSafe D3 Robotics

KeSafe D3 Robotics offers extended safety functions for robotics applications. They enable you to realize your products/facilities in accordance with the safety requirements for industrial robots pursuant to EN ISO 10218. KeSafe D3 Robotics modules are available for safety applications via KeStudio.

Benefits

Extended safety functionalities for robotics applications
Can be used for any series kinematics
Can be combined with KeSafe D3 PLC and KeSafe D3 Motion functionalities
Requirement: KeDrive encoder box and drive units with safre Hiperface-DSL encoders

Perfect match for safety and robotics

A key concept for KeSafe D3 is “invisible operation”. Security management should be invisible during normal production and should interact with the robotics control without being detectable for the user. KeSafe D3 is like an observer who continuously checks calculations, recognizes danger and acts without interrupting the manufacturing process unnecessarily.

Safety technology with KeSafe D3 at a glance

Four customized solutions

You can create holistic and safe robotics and machine applications with the following four hardware and software products. No additional safety assessment efforts are required.

Safety programming

KeStudio SafeEdit

Our engineering tool allows for simple and free programming of all safety applications using virtual links between the modules. Additionally, they include extensive diagnosis functions and support you in validating the safety application. You can create the maximum configuration for each machine option from the office and then adjust them easily to the machine on the production floor later.

Product features

Graphics editor for safety application (virtual links)
Supports all functional KeSafe D3 configuration levels (thanks to extensive technology modules)
Freely programmable: extensive diagnosis options and support in validation
Version management (machine options)

Safety control

KeDrive D3 with Safety Controller

The safety control combines safety logic and drive monitoring in a single device. Offers error-proof (onboard) inputs and outputs. This makes additional safety features for driver units unnecessary, with the exception of STO.
Simple safety functions to extended safety-based robotics solutions can be implemented without hassle.

Product features of KeDrive D3-DU 3x5

Best performance for I/O, single-axis and robotics safety
Quick reaction times
Highly integrated into functional controls
Can be expanded using safe bus protocols

Safety encoder box

KeDrive D3-SMM

The certified encoder box accepts decentralized inputs of encoder signals as well as additional secure inputs and outputs, which are sent to the control unit via a cable. The inputs make it possible to connect safe switches, buttons or other control elements directly to the machine or in the vicinity of the robot. All outputs are used for the safe control of engine breaks or are kept available for discretionary use.
In order to safely disengage the brakes (also without control cabinet), the safety functions are integrated directly into the encoder box - for example in order to prepare robots for transport or to monitor the speed (SLS) of disengaged axis.

Product features

Decentralized encoder analysis
Reduction of wiring
Flexible applications
Fast dynamics monitoring

Safe drive unit

KeDrive DMS2 Motor with Safety Encoder

KeDrive DMS2 driver units are available with the high-resolution hyperface DSL encoders. Thanks to modern digital safety encoders, safe high-performance applications can be realized in a cost-efficient and time-saving one-cable method.

Benefits:

Highest degree of reliability
High overload capacity
Low torque ripple
One cable for performance and encoder signal

Human-robot co-operation

Many years ago now, the automation expert from Austria investigated how applications in human-robot interactions could be expanded profitably, without a considerable need for programming.
We have systematically advanced the KEBA robot core with abstracted, reusable basic functions.

Safe co-operation with KEBA’s scalable safety solution KeSafe D3 is already available for all human-robot interaction applications subject to ISO TS 15066. The KEBA safety system for robots is not limited to any certain set of robot mechanics. KeSafe D3 is open and universal by design. It provides functions such as safe cells, safe Cartesian speeds and safe monitoring of tools for a vast variety of freely configurable robot types. Special features: Not only robots and their tools can be represented in the safety controls, but also additional axis moving the robot itself or with which the robot cooperates.

Safely interacting with industrial robots

In Industry 4.0, flexible production processes, safe human-robot interaction and fast robot teaching are only some of the crucial concepts.

Impressive safety controls by KEBA combine safety logic and drive monitoring in a single device.

Interesting insights into the KEBA laboratory How can industrial robots with sometimes high loads – such as 220 kg – interact securely with humans in the future? KEBA gives one possible answer.
