10 N Up to max. 130 N Takes effect starting at the
maximum gripping force
2.1.4.3 Program 3: AutoControl
Control with: One electrode or one linear control element or one switch
The hand closes at the fastest speed and grips an object with the lowest gripping force (10 N).
When the sensors recognise that the position of the object is changing, a readjustment is auto­
matically and continuously performed up to the respective gripping force required (max. 130 N).
FlexiGrip takes effect when the load on the hand exceeds 130 N (gripping force of the hand and
externally applied force). When there is no longer a load, the SensorHand Speed grips with the
previous gripping force again.
Control with one electrode
Opening: At maximum speed with fast, sustained muscle signal via the electrode.
Closing: At maximum speed with quick relaxation of the muscle.
Stopping: Relaxing the muscles very slowly via the electrode causes the hand to stop in the
open position.
Example 1: After opening, relax the muscle at very slow speed. The opening position remains
unchanged.
Example 2: After opening, relax the muscle at the fastest speed. The hand closes automatically
at the fastest speed and starts grasping the object with a gripping force of 10 N.
When the sensors recognise that the position of the object is changing, a readjust­
ment is automatically performed up to the maximum gripping force (130 N) as
needed.

10 N Up to max. 130 N Takes effect starting at the
maximum gripping force
Control with one linear control element
Opening: At maximum speed with a quick pull on the linear control element.
Closing: At maximum speed by quickly relaxing the pull on the linear control element.
Stopping: Relaxing the pull on the linear control element very slowly causes the hand to stop
in the open position.
Example 1: After opening, relax the pull on the linear control element very slowly. The opening
position remains unchanged.
Example 2: After opening, relax the pull on the linear control element at the fastest speed. The
hand closes automatically at the fastest speed and starts grasping the object with
a gripping force of 10 N. When the sensors recognise that the position of the
