Sway Control function description
6.21 Override
Step changes are permitted for the external override. The effect is delayed, as acceleration
limits are maintained internally.
Deviations from the trajectory calculated at the time of starting are possible during travel in
semi-automatic mode (SAM). Frequent and stepped changes of the override are the cause of
these deviations.
If the override is changed by an absolute value > 10%, the trajectory is recalculated.
Note
The operative override for the hoist is the minimum calculated from the input value
"OVERRIDE" (from the PLC) and the input value "hoist_BT_Field_Weak" (from the Basic
Technology).

● No override for hoist because no valid field-weakening value for hoist
● No override from the PLC interface
● Override on hoist is 20%. An output velocity is not output however, because the set
velocity = 0.
● Override for hoist follows the valid field-weakening value.
● Values from the PLC are limited because they are higher than the field-weakening value.
● Override for hoist is 40%
The value comes from the PLC because it is lower than the field-weakening value.
