Functional Safety Requirements for Robot Cells
Functional safety is about the reliability of the protective functions, not about the equipment alone.
What is considered
| Element | What it covers |
|---|---|
| Risk assessment | Identifying hazards and required risk reduction |
| Safety functions | Defined responses such as safe stop and safe speed |
| Performance level | The reliability required of each function |
| Validation | Evidence that each function performs as specified |
Practical steps
- Document every safety function, its trigger and its response.
- Keep safety-related circuits separate from standard control logic.
- Re-validate after any modification to the cell.
The required level for each function follows from the risk assessment. Confirm with a competent specialist.
