Tab. 19 "GrippingForce" parameter
Parameters "GrippingTolerance"
With this parameter, a tolerance can be set for the gripper exclusively for the "GrippingPosition" para-
meter. This functionality is helpful, for example, when checking the correct workpiece.
The entered value is effective in both directions of the "GrippingPosition". The total tolerance field
width is therefore twice the tolerance value.
Parameter
"GrippingTolerance"
Tab. 20 GrippingTolerance" parameter
The following repeat accuracy can be achieved:
EHPS-...-A-LK
Repetition accuracy
Tab. 21 Repetition accuracy

Linearity
Tab. 22 Linearity
In the case of a gripper exchange, the taught-in and stored in IO-Link Data Storage positions of the
workpieces can be returned by the displacement encoder with the following accuracy (plus tolerance
of the gripper fingers):
EHPS-...-A-LK
External gripping interchangeability
Internal gripping interchangeability
Tab. 23 Interchangeability
Parameters "WorkpieceSet"
In the gripper, 4 parameters can be defined for each of 32 different workpieces
