ROBOTIQ HAND-E - 4.9.4. Limiting your Gripper Force and Speed

Robotiq Hand-E Gripper - Instruction Manual
6.2.3. Moment and force limits
The Hand-E Gripper has limits for moment and force values. The maximum moment and force values are independent of the grasp
force applied by the Gripper on its payload. For payload calculation, please refer to the Payload and force section.
Warning
The following limits must be respected at all times.
Calculation of maximum moment and force should include robot acceleration and safety factors.

Usage examples with listed limits:
l After picking its normal payload, the robot can use Hand-E to apply up to 100 Nof force in any direction. Applying more than 100 N
can damage the Gripper or result in payload loss.
l The Gripper can pick a screwdriver and apply 2 Nm of torque to screw (such a moment would be applied in the Z axis).
