2.7 Maximum Wrist Payload
The installation payload at the front of the wrist is affected by the maximum
carrying weight of the wrist, the Maximum payload torque value, and the
maximum moment of inertia. The maximum payload torque changes depending on
the actual moment of inertia. The wrist payload should be strictly controlled within
the value range. Otherwise, normal operation cannot be guaranteed.
