Fig. 22 Simple travel task
If the new_set_point bit as well as the change_set_immediately bit of the control word are
set to "1", the master instructs the drive controller to start the new travel task
immediately.
A travel task already being processed in interrupted in this case as shown in Fig. 23.
For this purpose, the master transfers the next target to the drive controller after the
controller has signalled by deleting the set_point_acknowledge bit that it has read the
buffer and started the corresponding positioning. Here it is important that the new travel
task is transferred to the drive controller in time.
