Fig.5/10:Pulse−time diagram  automatic brake
In this example, both the time for switching to the next record
and the activation time of th
e automatic brake (T Automatic)
starts to run after the completion of a positioning record
(MC). After the activation time has expired, the brake is
clo
sed and the switch−off time runs simultaneously. After the
switch−off time has expired, the controller end stage is
switched off (less warming).
Aft
er the time for switching to next record has expired, there
is a new internal START signal, the drive, however, does not
start to
move until the switch−on delay has expired.
