2 Product description
2.1 SensorHand Speed with SUVA sensors
2.1.1 Grip stabilisation system
The grip stabilisation system of the SensorHand Speed prevents the object being held from slip­
ping by automatically increasing the gripping force. This process is interrupted as soon as the
object is secured. Sensors integrated into the SensorHand Speed make this possible.
Grip stabilisation is only possible up to the maximum value for automatic gripping force readjust­
ment and is intended for programs 1–4. Program 6 is intended for gripping soft foams or tools.
Automatic gripping force readjustment can be stopped at any time with a brief “OPEN” impulse.
2.1.2 FlexiGrip
The FlexiGrip function allows a grasped object to be turned or shifted in the hand without having
to loosen the grip via electrode signals and subsequently re-grip the object.
The SensorHand Speed follows the changes in the position of the gripped objects like a natural
hand would. This makes the grip flexible.
The FlexiGrip function can be stopped at any time with a brief “OPEN” impulse.
2.1.3 Unlocking/locking the wrist joint (8E43=*)
The individual flexion and extension of the wrist
joint can be locked in five different positions (in
20° increments each).
1) Press the release button in the direction
indicated by the arrow.
2) Move the terminal device to the desired
position while holding the release button.
From the relaxed hand position, it engages
at 20° and 40° in each direction.
3) Let go of the release button to lock the ter­
minal device in the respective position.
2.1.4 Program description
Six different control variants can be configured by the O&P professional with this terminal device.

switch, or with one switch only)
• Program 3: AutoControl (control with one electrode, with one linear control element or with
one switch)
• Program 4: VarioControl (control with one electrode or with one linear control element)
• Program 5: VarioDual (control with two electrodes)
• Program 6: DMC plus Sensorik, can be deactivated (control with two electrodes)
