Error in semi-automatic mode
E30 (Bit 31) No path found
Semi-automatic mode (SAM) was unable to find a path between the starting position and the
target position:
● For "on-the-fly unloading," the highest point of the calculated travel curve is higher than the
target. Travel in semi-automatic mode will not start.
● Target cannot be reached because there is an obstacle in the way. Travel in semi-automatic
mode starts; the target is placed in front of the obstacle however.
If the target is in a fixed blocked region, no travel of the crane is initiated and E38 is issued.
Error type:
Error
Remedy:
Check starting position and target position as well as blocked regions
