Comments
According to currently
applicable standards
(TC143), the SG function
– depending on the
technology – is only
permissible in combination
with agreement, jog mode,
start button and
Emergency Stop
According to currently
applicable standards
(TC143), the function –
depending on the
technology – is only
permissible in combination
with JOG mode, start
button and Emergency
Stop
No wear, safe
disconnection of energy
feed to drive to allow
manual intervention in
danger zone; function
does not replace machine
main switch
with respect to electrical
isolation
Wear-free safe cams,
are essentially used for
machinery protection,
can also be used to
restrict working zones in
conjunction with personnel
protection
Wear-free "safe software
cams"
used to safely detect the
position of axes.
Can be used to demarcate
physical areas
External two-channel
inputs or further
processing required if
function is intended to
protect operating
personnel
