Safety information and
considerations
Contents of this chapter
This chapter contains general safety considerations and information to be taken into
account when applying the FSO safety functions.
WARNING! The FSO safety functions module is delivered with the safety
functions bypassed by jumper wires in connectors X:113 and X:114 to allow
initial drive commissioning without the need to configure safety functions first.
The safety system must always be properly commissioned and
verified/validated before it can be considered safe.
WARNING! Make sure that the functional safety of the machine is maintained
in situations where the safety option does not provide protection, for example,
during commissioning, system maintenance, fault tracing, or
decommissioning.
Use of safety functions
To make sure that the application, where FSO and its safety functions are used, is
safe to use and fulfills all relevant safety requirements, it is necessary to take into
account the requirements of the local (machinery) safety legislation (eg, Machinery
Directive) and/or the applicable functional safety standards (eg, ISO 13849-1).
Implementing safety functions to make safe applications requires a systematic
approach/process, where risk assessment is the basis of all safety requirements.
These processes are described in global ISO and IEC machinery safety and
