(1200 mm)
● H_ALT = 1200 mm, S_ACT = 1800 mm, L_ACT = 1400 mm, → Case g → H_NEU = L_ACT

● H_ALT = 1400 mm, S_ACT = 1200 mm, L_ACT = 1900 mm, → Case k → H_NEU = S_ACT
(1200 mm)
Note
The time difference between the moment of transmission by the bay scanner and the moment
of receiving in the SIMOTION D4x5-2 DP/PN causes inaccuracy of the measured values (or a
shift in the obstacle profile), in particular when the trolley is moving. This inaccuracy must be
taken into account by setting appropriate safety clearances P33 and P72 (for SAM), and P29
and P78 (for MAN).
Danger to life due to erroneous values for the current positions S_ACT for the hoist and the
trolley
If the current positions for the hoist and the trolley do not correspond to reality, incorrect
blocked regions may be calculated even if the bay scanner is functioning correctly. This can
result in collisions that may cause injury or death.
● Make sure that valid values for the positions are transferred by the crane control system.

WARNING
This not only applies to automatic travel in semi-automatic mode (SAM). Valid position
values for the hoist and trolley must also be available in manual (MAN) mode when
learning travel is performed.
