ASK THE EXPERTS
If I have a robot with a failsafe control unit, but it is not specifically a power and force limited model, can I myself build the necessary speed and torque limits into its motion to allow it to be used in a power and force limited operation?

Doing so would require modification of the robot controller and drives. This will completely void any warranty and liability of the manufacturer. Check with the manufacturer but, as a rule, these functions cannot be added to an existing robot.
The robot manufacturer has to answer this question. I presume it is Yaskawa because of the name "FSU". The robot manufacturer has to state whether they have safety functions for the purpose of power and force limiting.
