In this example, both the time for switching to the next record
and the activation time of the automatic brake (T Automatic)
starts to run after the completion of a positioning record
(MC). After the activation time has expired, the brake is
closed and the switch−off time runs simultaneously. After
the switch−off time has expired, the controller end stage is
switched off (less warming).
After 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.
