6.3.2 Program description
INFORMATION
Both the automatic gripping force readjustment and the FlexiGrip function can be stopped at
any time with a brief "OPEN" impulse.
INFORMATION
All gripping force specifications (e.g. 100 N ~ 10 Kp) are non-binding guiding values to illustrate
the functional principle of the various operating modes.
6.3.2.1 Program 1: DMC plus Sensorik
Control with two electrodes
This control variant corresponds to DMC plus control with the integrated "virtual hand switch"
(dynamic mode control) but also features the "SUVA sensors" grip stabilisation system. The level
of the gripping speed or gripping force is determined by the strength of the electrode signal (res­
ulting from the muscle contraction). After gripping with maximum force, the activation threshold in
the OPEN direction is raised to a higher value ("virtual hand switch"). This increase reduces the
