Positioning (POS)

6.2.2.1

Method of operation

In positioning (POS) mode, the higher-level control system can specify a target position for
each individual drive. This position is approached automatically after enabling. The trolley is
controlled in such a way that the load sway is eliminated not only when the positioning velocity
is reached, but also at the target position.
It is not necessary for both drives to be in this operating mode at the same time.
Danger to life due to failure to observe blocked regions
Blocked regions are only observed in semi-automatic mode (SAM) and, if activated, in manual
mode (MAN).
In all other modes, i.e. also in positioning mode, collisions that may result in injury or death are
possible due to inattention of the crane driver.
In POS mode, the blocked regions must be taken into account in the crane control.
Further information
Further different control options in this operating mode are described in Chapter: Hoist takeover
(Page 221).
