5.4Robot working envelope diagram
5.5Robot load curve
Overview: Any load applied to the robot must follow the robot load map to avoid unstable operation of the robot, motor, reducer, and structural overload.
The load loaded by the ERB80 robot must conform to the ERB80 robot load curve. The mass of the load and its own inertia must be confirmed under various conditions. Overloading will overload the motor and reducer, shortening the life of the robot, and serious damage to the robot.
