SIMATIC Safe Kinematics
Highest safety for human and machine
Digitalization increases the degree of automation of machines and systems with an impact on production processes. Here, more and more handling tasks are being taken over by robots with high demands on velocity, precision and repeatability. Industrial robots often work in a cell surrounded by a protective fence. But is that enough to adequately protect the operator? Only with the corresponding efforts – and this requires valuable space or is expensive. The alternative is SIMATIC Safe Kinematics: The software-based solution can monitor the movement in the multidimensional space of predefined kinematics with up to 12 interpolating axes in a fail-safe manner.
An alternative to protective fences
Industrial robots often work in production cells surrounded by protective fences. This ensures that operators cannot reach the hazardous areas within the cells. Classic protective fences are often deceptive, as these would not withstand collisions with the robot.
Usually there are two ways to ensure safety here:
1. Distance
The protective fence must be installed in a way that there is a sufficient distance between the protective fence and the robot so that the robot cannot reach and deform the protective fence, thus endangering the operator. As a result, the space requirement of the robot cell increases and the costs of the longer protective fence have to be accepted.
2. Robust protective fence systems
If the robust protective fence can retain the static and dynamic forces of the robot at maximum operating velocity and load, this protective fence may be installed closer to the robot. These robust protective fence systems result in significantly higher costs compared to a classic protective fence..
With the software-based SIMATIC Safe Kinematics solution, Siemens now offers another flexible alternative.
Fully integrated and certified software-based solution
In order to ensure safety and increase the efficiency of machines, a safe interaction between the machine operator and the machine is necessary.

Functionality
The safe monitoring of the kinematics is carried out in the program of a fail-safe SIMATIC S7-1500 control by means of SIMATIC Safe Kinematics in combination with the drive system SINAMICS S120. The complete engineering takes place uniformly in the TIA Portal.
No, but instead of an expensive safe protective fence with corresponding space and investment requirements, a normal protective fence is sufficient.
With SIMATIC Safe Kinematicsyou can safely prevent the robot from colliding with the protective fence. As soon as the robot arm leaves the "working zone", it is immediately shut down, thus preventing a collision with the protective fence. Classic protective fences can be used and the robot cell can be built more compactly because the protective fences can be mounted closer to the robot.
SIMATIC Safe Kinematics requires safe position information of all axle joints
In order to be able to monitor a kinematics with SIMATIC Safe Kinematics safely, you need safe axis positions of the kinematics. For this purpose, we recommend the drive-based safety function Safe Position (SP) of the SINAMICS S120, which transmits the safe axis positions via PROFIsafe to the F-PLC.
SIMATIC Safe Kinematics is independent of the robot's non-safety motion control
SIMATIC Safe Kinematics can either be operated together with the kinematics technology object on a TF CPU of the S7-1500.
CPU 1517TF‑3 PN/DP
CPU 1515SP PC2 TF with CPU 1505SP TF
Or be used on a fail-safe S7-1500 CPU for independent monitoring of a separate kinematics controller
CPU 1517F‑3 PN/DP
CPU 1518F‑4 PN/DP

SIMATIC Safe Kinematics V2.0 is an option package from TIA Portal and will be reinstalled as a setup in TIA Portal V16 from update 1. The product contains a fail-safe block library, which must be integrated into the programming environment of STEP 7 Safety Advanced and connected on the input and output side.
