4.9.1.1 Function of SOS
The SOS function monitors the count value
and notifies the user if the encoder/count
deviates more than a defined amount from
the stopped position.
Example of how the function can be used
A protective door can only be opened if a machine
is in the safe standstill state.
• Stop the movement of the hazard from your
safety program.
• Ensure no further movement as follows:
– Engage/energize (brake/motor)
– Engage the safety related actuator
• Enable SOS monitoring in the counter mod-
ule via the safety program in the F-CPU
• Disable the door lock to permit access to the
machine
• Perform an appropriate safety reaction if the
"Safe Stop Event" ever occurs
