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 ARS 2000 FS servo drives 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 ARS 2000 FS servo drives 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 drives 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.
6.1.1 DIP switch
The FBA module (Fieldbus Activation Module) and all of the integrated functional safety modules (FSM
2.0) are equipped with a DIP switch (8 poles). Under certain conditions, substantial parts of the
parameters of the fieldbus communication can be configured with the aid of this DIP switch. Depending
on the fieldbus that is used, it is possible, for example, to adjust the fieldbus node number, baud rate, etc.
This DIP switch does not have a safety-relevant function.
The following applies in order to achieve downward compatibility with the previous ARS 2000 devices:
 If all of the switches on the module are set to zero (factory setting), the fieldbus communication
parameters of the parameter data set of the basic device will be used.
INFORMATION
The position of the DIP switch is read in only once after a reset. Modifications of the
switch positions during the operation, therefore, do not affect the current operation.
