"Safe stop 1 (Emergency stop)" function with "L3" option
Using the E-Stop function of the drive (or the NC stop of the control unit), the
STO function can be extended to obtain the "Safe stop 1 (Emergency stop)"
function. For this purpose, the selecting safety unit (active or passive) must
first shut down the drive by means of the E-Stop function (or the NC stop of
the control unit) and select the STO function after a fixed time that has been
set is over. The selection must always take place after the time that has been
set, independent of the state of the axis.
The figure below shows KCU02 as a zone beginner. The E-Stop signal is
wired to X50 of KCU02 and is transmitted to the zone nodes via the hybrid
cable.
