Figure 9-5 Safety Integrated signal flow application example
Note
This example illustrates implementation options. The solution required for the machine must
be suitable for the machine function, which means that parameters and control commands
are defined individually.
NOTICE
The fault responses and output functions (e.g. inversion or simulation) must not be changed
or activated with respect to the factory setting.
Description of functions
With two SIGUARD safety combinations for emergency stop and the protective door, as well
as a standard PLC, the system can be configured according to EN 954-1, category 3, and
EN1037. The drives are brought to a standstill in accordance with stop category 1 to EN
60204-1.
