Example
The figure below shows a brake control application example.
WARNING!
Make sure that the machinery into which the drive with brake
control function is integrated fulfils the personnel safety regulations. Note
that the frequency converter (a Complete Drive Module or a Basic Drive
Module, as defined in IEC 61800-2), is not considered as a safety device
mentioned in the European Machinery Directive and related harmonised
standards. Thus, the personnel safety of the complete machinery must not
be based on a specific frequency converter feature (such as the brake
control function), but it has to be implemented as defined in the application
specific regulations.
