6 Functional safety technology
6.1 General
With an increasing degree of automation, the protection of persons against dangerous movements becomes increasingly
important. Functional safety describes the necessary measures in the form of electrical or electronic devices for the reduction
or elimination of hazards caused by malfunctions. Under normal operating conditions, protective devices prevent access of
persons to dangerous areas. In certain operating modes, however, for example during the set-up, persons are required to be
present in these dangerous areas. In these situations, the machine operator must be protected by drive- and control-internal
measures.
The integrated safety technology provides the control- and drive-specific conditions for the optimal realisation of protective
functions. Planning and installation become less labour-intensive. Compared to conventional safety technology, the machine
functionality and availability can be increased by the use of integrated safety technology.
In their delivery state, the item servo positioning controller C Series are not equipped with any integrated functions for safety-
related motion monitoring and motion control. However, they have an extension slot for a safety module.
As a standard, the item servo positioning controller C Series come supplied with the module FSM 2.0 – FBA (Fieldbus
Activation Module) integrated in the extension slot for safety modules. You can remove this module and replace it with a
functional safety module.
If the safety modules of the FSM 2.0 series (Functional Safety Module) are used, external monitoring devices are no longer
required for numerous applications. The wiring of the entire system is simplified and the number of components as well as the
costs of the system solution can be reduced.
The design of the safety modules ensures that they can be simply plugged into the basic device from the outside. As a result,
the servo positioning controllers can be quickly adapted to the specific safety requirements of the overall system. Retrofitting
of these modules (or the later use of a different safety module), thereby, becomes possible. The module is supplied with power
via the power supply of the basic device.
