2.3 Movement (Feed) of Elevation Unit
(1) Overall/General Sequence
In this sequence, the elevation unit is moved to a designated shelf of the cassette set unit in
order to feed IPs.
The movement of the elevation unit cannot be performed if the suction cups are not in their
home position (HP).
If there is any IP being fed, the machine waits until the suction cup movement process
described in "2.6 (3) Sequence of Side-Positioning Conveyance" is completed.
