2.7 Allowable Value of Wrist Payload
Attention
The installation payload at the front end of the robot wrist is affected by the allowable
weight of the wrist, the allowable payload torque value, and the allowable moment of
inertia. The allowable payload torque value changes according to the actual payload
moment of inertia. The wrist payload should be strictly controlled within each
allowable value. When using the robot with a wrist payload other than the allowable
value, normal operation cannot be guaranteed.
