Safety
Safer applications
In addition to the qualitative approach to safety required by the EN 954-1 standard, EN 13849-1 demands a quantitative calculation of safety functions. In many installations, this leads to the use of a safety control being required. As a member of the PLCopen Safety Organization, Baumüller has taken the new safety requirements in the automation industry on board and provides PLCopen Safety-compliant security solutions that can be integrated throughout the machine's automation system.
The concept comprises centralized, modular decentralized and hybrid automation structures and is reflected across every application area. In this way, Baumüller is able to integrate its safety concept into all automation components, including communication systems and the Engineering Framework ProMaster.

- Simple commissioning and effective diagnosis
- Simplified certification of the safety application
Integrated Safety Technology and the Machinery Regulation
Starting in January 2027, the new Machinery Regulation (EU) 2023/1230 will apply within the EU European Economic Area, replacing the Machinery Directive 2006/42/EC.
The Machinery Regulation (MVO) is intended to ensure the safety of people and machinery. It was introduced to adapt regulations to the latest state of the art and to provide clarity on previously contentious points. A new addition to the Machinery Regulation is the protection of machines against intentional and unintentional corruption.
The MVO affects all manufacturers, distributors, or importers of machinery, as well as authorized representatives, i.e. persons commissioned to handle specific tasks. An assembly of linked parts or devices, at least one of which moves, and which are joined together for a specific application, is also considered a machine.
The MVO also applies to safety-related components and thus also to Baumüller’s integrated safety technology.
Overview of some key changes regarding the Machinery Directive:
- Direct applicability: The Machinery Directive applies directly in all EU Member States and does not require national transposition.
- Extended scope: Applies to machinery and associated products (e.g. safety components).
- Digital documentation: Technical documentation and operating instructions are provided in digital form as standard; paper copies only on request.
- Cybersecurity: New requirements for protection against external attacks, unauthorised access and software risks.
- New technologies such as artificial intelligence, automation and autonomous machinery are included.
- New risk categories and specific categories for high-risk machinery have been introduced.
- Life cycle: Manufacturers must also take into account risks arising from software updates and digital development.
As of January 20, 2027:
- We ensure the conformity of our safety-related components in accordance with the MVO
- We have all necessary documents, test results, and evidence ready
- We apply the corresponding CE marking
Pluggable safety for the b maXX 5000
Our four modules for the b maXX 5000, in the form of plug-in cards, are the ideal solution for drive-based safety. Depending on the application, the machine manufacturer can quickly and flexibly adapt the converter to match the requirements.
| Safety functions | Safely accessible via | Parameter memory | |
|---|---|---|---|
| SAF-000 | - | - | yes |
| SAF-001 | STO | I/O | yes |
| SAF-002 | STO, SS1, SS2, SOS, SDI, SLS, SBC | I/O and fieldbus | yes |
| SAF-003 | STO, SS1, SS2, SOS, SLA, SLS, SLP, SLI, SDI, SBC,SSM,SCA | I/O and fieldbus | yes |
Threefold safety with our safety modules
The safety modules SAF-001, -002 and -003 ensure the required level of safety both to current standards and for the future. The scalable functionality of these modules ensures the b maXX 5000 perfectly satisfies the requirements of the EN ISO 13849 to SIL 3 and EN 62061 to PLe standards.
By simply plugging in the SAF modules, the user can react quickly and flexibly to new requirements. All modules are equipped with an integrated parameter memory, which contains all safe and unsafe parameters that are set on the b maXX's drive controller. The safety functions are selected via the safe I/Os or EtherCAT FSoE on the safety module.
Set drive safety parameters easily and intuitively with ProSafePara
Baumüller is one of the few drive and automation vendors providing universal, integrated safety solutions for centralized, modular decentralized and hybrid automation structures which comply with the standards of Machinery Directive EN ISO 13849-1 and EN IEC 62061 up to Performance Level e and Safety Integrity Level 3. The ProMaster engineering tool supports parametrization of the b maXX safety modules SAF-002 and SAF-003. ProMaster allows scalable integration of b maXX 5000 safety modules into standard automation equipment using the integrated and secure ProSafePara parametrization environment.
Parametrization page for SLS (safe speed) safety function
Via ProSafePara, the safety technology is fully integrated into the ProMaster engineering tool and accesses the same project database. ProSafePara was developed in accordance with the requirements of standard IEC 61508 and covers the entire range of safety requirements up to SIL 3, so completely safe parametrization of the SAF-002 and SAF-003 safety modules is guaranteed.
