Conformance With Eu Machinery Directive, Functional Safety; Brake Interruption Contact (Required For Sbc) - Kollmorgen MKD-C Guía De Seguridad Del Producto

MKD Product Safety Guide | 8 Appendix

8.5.4 Conformance with EU Machinery Directive, Functional Safety

Conformance with the EC Machinery Directive 2006/42/EU is mandatory for the supply of
safety components within the European Community. Kollmorgen declares the conformity of
the MKD modules with the following directives:
Resulting Functional Safety classification (SIL and/or PL level) for SBC must be calculated
across the drive system.
8.5.4.1 Safe Torque Off (STO)
The STO implementation on the MKD is certified by TÜV. The safety circuit implementation
used for the safety function "Safe Torque Off" in the drives is suited for SIL 2 according to
IEC 62061 and PLd / CAT3 according to ISO 13849-1.Certificates can be found on the

8.5.4.2 Brake Interruption Contact (required for SBC)

The brake interruption contact can be used to implement an SBC (Safe Brake Control)
functionality to the application. The implementation on the MKD is certified by TÜV for
applications up to SIL 2 according to IEC 62061 and PLd / CAT2 according to ISO 13849-1.
Resulting Functional Safety classification (SIL and/or PL level) for SBC must be calculated
across the drive system. Component quality selection for logic and brake depends on the
objectives to be achieved for PL and SIL. This must be determined and implemented by the
user.
