Safety-related variable speed drives (VSD) in EC Machinery Directive 2006/42/EC


The revised Machinery Directive (2006/42/EC) gives a broader definition of a safety component than its predecessor, and Gambica members who are manufacturers of electronic variable speed drives group, including Schneider Electric and Mitsubishi Electric are increasingly offering safety-related control functions in their products as a result.   This has resulted in a number of questions being asked; most often:


 Frequent questions

-Does a variable speed drive with safety functions fall within the definition of “safety component” according to Directive 2006/42/EC, and if so, does it fall within one of the categories listed in Annex IV?
-What is the status of a variable speed drive which offers safety functions as an option through the addition of a module which is available for sale separately?


-What requirements apply with regard to an EC Declaration of Conformity and CE marking?


As a result, in October 2011 Gambica issued a position statement that can be found on  the variable speed drive section of the Gambica technical publications website.


GAMBICA is the national organisation representing the interests of companies in the instrumentation, control, automation and laboratory technology industry in the UK.
