Sway Control function description
6.9 Immersion point
The immersion point is limited internally by the initialization value and the minimum position for
positioning the hoist (P63).
Calculating the initialization value for the immersion point
The initialization value is calculated by the system according to the locking state of the spreader.
Table 6-1
Locking state of the spreader
None of the containers is locked.
The control bits LOCKED_BIT0 and LOCKED_BIT1 are
reset.
At least one container is locked.
At least one control bit, i.e. LOCKED_BIT0 or LOCKED
_BIT1, is set.
P69: Maximum position for positioning, hoist
P108: Maximum container height
Setting the immersion point
When the control bit LEARN_PROFILE_RESET (STW1_PLC_Common) is set, the immersion
point is set to the initialization value. The internally learned variable blocked regions are deleted.
In the MAN and POS modes, the immersion point is dynamically set to the current hoisting
height when:
● The trolley on the waterside moves at a velocity above P46 (immersion point velocity limit).
● The hoist is located below the previous immersion point.
Example
● P46: 30% (velocity limit)
● P0: 3500 mm/s (maximum output velocity)
– Velocity limit = 1050 mm/s
● Immersion point at the beginning (before traveling over the waterside): 31000 mm
