CAUTION
Damage to the gripper is possible!
If the maximum permissible finger weight or the permissible
mass moment of inertia of the fingers is exceeded, the gripper
can be damaged.
•
A jaw movement always has to be without jerks and bounce.
•
You must therefore implement sufficient reduction and/or
damping.
•
Observe the diagrams and information in the catalog data
sheet.
CAUTION
When using the main air connections "A" and "B" with PWG-plus
50 – 200 the gripper must be throttled by external throttle
glands.
•
Do not remove pre-assembled fixed throttle fittings
CAUTION
When using the main connection "a" and "b"a throttle for PWG-
plus 50 – 200 is not required.
•
Attach the supplied fixed throttle screw connection to the
connections of the adapter plate.
NOTE
• Observe the requirements for the compressed air supply,

• In case of compressed air loss (cutting off the energy line), the
components lose their dynamic effects and do not remain in a
secure position. However, the use of a SDV-P pressure
maintenance valve is recommended in this case in order to
maintain the dynamic effect for some time. Product variants
are also offered with mechanical gripping force via springs,
which also ensure a minimum clamping force in the event of a
pressure drop.
