Remarks
According to the
status (TC143), the
SG function is only
permissible with
protective safety
devices/guards
(e.g. protective
doors)
Low-wear safe
disconnection of
the energy feed to
the motor to allow
manual
interventions in the
hazardous zone
(safe location),
This function does
not replace the
main machine
breaker/switch
regarding electrical
isolation
Wear-free safe limit
switch,
essentially used for
machinery
protection.
It can also be used
to restrict working
zones in
conjunction with
personnel
protection.
Wear-free "safe
software cams" for
safety-related
detection of axis
positions,
can be used to
demarcate
physical areas
External
two-channel inputs
or further
processing
required if function
is intended to
protect operating
personnel
