Gripping force of end effector
The gripping force of the end effector must have a sufficient extra margin of
strength versus the workpiece weight and reaction force applied to the work-
piece during robot operation.
The reaction force applied to the workpiece during operation can be calculated
from the acceleration applied to the end effector attachment. The maximum ac-
celeration on the end effector attachment of each robot model is listed in the ta-
ble below. When the workpiece position is offset to the end effector attachment,
the accelerations Amax and A
offset versus the arm length. When the R-axis rotates during operation, this ac-
celeration A

WARNING
THE GRIPPING FORCE OF THE END EFFECTOR MUST HAVE A
SUFFICIENT EXTRA MARGIN OF STRENGTH TO PREVENT THE
WORKPIECE FROM COMING LOOSE AND FLYING OFF DURING ROBOT
OPERATION.
IF THE GRIPPING FORCE IS TOO WEAK, THE WORKPIECE MAY COME
LOOSE AND FLY OFF CAUSING ACCIDENTS OR INJURIES.
