Fundamentals of Controlled Positioning Using the Analog Output

Positioning Operation
From the start position, the speed is increased (rapid feed) and the destination is
approached at this speed. At a preset distance from the destination (switchover point), there
is a change to a lower speed (creep feed).
Shortly before the axis reaches the destination and also at a preset distance to the
destination, the drive can either be switched off (switch-off point) or be slowed down from
creep feed to 0.
To facilitate understanding, the change in speed is illustrated over the path traversed.
