Example of dynamized selection signals
The figure below illustrates, in schematic form, the interconnection of an
active safety unit and multiple drives with a "T option":
Fig. 5-3:
Dynamization in the case of selection via an active safety unit
When choosing the safety unit, the maximum current
consumption of the selection inputs of all drives of a safety zone
has to be taken into account.
Dynamization in the case of selec‐
tion via passive safety units
A passive safety unit is a safety switching device with which the
safe function is selected via isolated contacts.
When the safety functions of the "T options" are selected via a
passive safety unit, the drive checks the wiring of the selection.
When the safety functions are selected via a passive safety unit, the drive
generates the dynamization pulses and makes them available via the
"STO_DynOut_CH1" and "STO_DynOut_CH2" outputs at the XG41
