3.1.3. Precautions

1. When the robotic arm is in the zero position, the gripper will

exceed the installation surface. Please adjust the robotic arm to a

posture suitable for installing the gripper during installation.
2.When a robotic arm equipped with a gripper is used for

trajectory planning, it is necessary to perform a safety

assessment on whether to return to the zero-point or whether the

operation can be performed and to avoid collisions.

The gripper of the robotic arm in the zero position will exceed the mounting surface.
