7.2.3.3 Operating modes
In setup mode, the functionality of the setup/positioning block becomes
available. This function block can be found in function diagram 789b
and is assigned to a time slot using parameter U953.61.
Setup means position-controlled jogging.
In setup mode (SETUP_ON or SETUP = 1), the axis is moved under
position control by means of the direction selection [D_FWD] and
[D_BWD] taking into account the set values for acceleration and
deceleration and the speed.
