Figure 14: Gripping area and gripping direction
If the base jaws are blocked outside the position window, e. g. at the end stop of the movement, the
gripped part is considered released or no part has been detected, depending on the direction of
movement.
Danger of collision. If the gripping area is not sufficiently large, parts that are too small or too large
may be gripped, although the gripping state is NO PART or RELEASED. If in doubt, please check the
current jaw position.
9.6.1
Gripping Direction
The gripping direction is determined by the RELEASE Limit and NO PART Limit. When the position for the NO
PART Limit is smaller than that for the RELEASE Limit, the gripping module performs an inward grip (Figure14,
“Gripping Outside”). When the position for the NO PART Limit is larger than that for the RELEASE Limit, the
gripping module performs an outward grip (Figure 14, “Gripping Inside”).
