Pre-positioning force profiles
Gripping in the direction of WorkPosition
For Mode Groups 80 and 90, pre-positioning is
used. Therefore, these groups are particularly
suitable for time-optimized gripping with long
strokes followed by force-fit gripping.

GripVelocity
(calculated)
The gripping force is built up by the movement
speed of the product and the motor current.
The product calculates the required GripVe-
locity automatically from the GripForce
parameter.
For opening, the product moves toward the
standby position at DriveVelocity. The product
switches into positioning mode automatically.
The graphic shows outside gripping using
mode group 80 as an example. For Mode
Group 90, the BasePosition and the WorkPo-
sition are exchanged.

Since gripping should occur in one direction only, the positioning mode is used automatically in the opposite direction.
The movement profile determines the direction in which the workpiece is gripped:
• Outside gripping: Movement profile group 80
• Inside gripping: Movement profile group 90
