Additional safety information and residual risks not specified in this section are included in
the relevant sections of this Function Manual.
Risk minimization through Safety Integrated
Safety Integrated can be used to minimize the level of risk associated with machines and
plants.
Machines and plants can only be operated safely in conjunction with Safety Integrated,
however, when the machine manufacturer:
• Precisely knows and observes this technical user documentation - including the
• Carefully constructs and configures the machine/plant. A careful and thorough
• Implements and validates all the measures required in accordance with the
The use of Safety Integrated does not replace the machine/plant risk assessment carried
out by the machine manufacturer as required by the EC machinery directive.
In addition to using Safety Integrated functions, further risk reduction measures must be
implemented.
Safety Integrated functions not active until power-up is completed
The Safety Integrated functions cannot be activated until the system has been completely
powered up. System startup is a critical operating state with increased risk. No personnel
may be present in the immediate danger zone in this phase.
The drives of vertical axes must be in torque state.
Regulations from EN 60204-1
The Emergency Stop function must bring the machine to a standstill according to stop
category 0 or 1 (STO or SS1).
The machine must not restart automatically after EMERGENCY STOP.
When individual safety functions (Extended Functions) are deactivated, an automatic
restart is permitted under certain circumstances depending on the risk analysis (except
when Emergency Stop is reset). An automatic start is permitted when a protective door is
closed, for example.
