NOTICE
T
he area outside of this system falls within the user’s area of responsibility.
The actuator is not part of the safety system. These components must be introduced by
t
he user of the safety system in order to implement the full safety function. They must
be taken into account in the overall assessment.
3.7 Product characteristics
3.7.1 Safety functions
The Safe Linear Positioning safety system offers the following functions:
•
S
afe stop 1
°
This stop function corresponds to stop category 1 as per EN 60204.
•
Safe stop 2
°
This stop function corresponds to stop category 2 as per EN 60204.
•
Safe position monitoring
°
The Safe Linear Positioning safety system enables reliable position monitor‐
ing through the SCA (safe cam) and SLS (safely limited speed) functions.
•
Safely limited speed
°
The position ranges within which only limited speeds are permitted must be
saved as parameters in the Flexi Soft safety controller program. The Safe Lin‐
ear Positioning safety system determines these position ranges automatically
and monitors the speed.
If the maximum permitted speed is exceeded, the Flexi Soft safety controller
initiates a safe stop 2.
°
The safely limited speed can also be activated by an internal signal in the
controller or an external signal. This makes it possible for external processes
to activate monitoring of the safely limited speed.
WARNING
T
here is a risk of death or serious injury as the protective device cannot be
relied upon to monitor speeds that are too low.
Select the correct components in line with the risk assessment.
The lowest speed that can be monitored will depend on the sensor unit in
use. It is either 75 mm/s (part number 1087575) or 9 mm/s (part number
1090629).

Emer
gency stop (shutting down in an emergency)
°
The safety controller of the Safe Linear Positioning safety system provides a
safe dual-channel input to allow for the machine to be shut down in an emer‐
gency.
