By adding Mitsubishi Electric Factory Automation’s robot safety option to a Mitsubishi Robotic solution, your robots can perform in a cooperative mode with your operators. The "robot safety option", used together with external devices such as a safety switch or light curtain, enhances the robot safety function. Cooperative Robotic applications are applications where the operator and machinery are mostly operating in their own space but need to interact occasionally for short periods of time.

The robot safety option adds the following functionality:

• Safe Torque Off (STO): The function shuts off driving energy to the motors of the robot. • Safe Operating Stop (SOS): Without shutting off the driving energy to the motors, this function monitors the robot so that it stays at rest. • Safe Stop Function 1 (SS1): This is a function to stop the robot safely. After stopping the robot, power off the motors. • Safe Stop Function 2 (SS2): This is a function to stop the robot safely. While the motor control keeps working after the robot stops, this function monitors the robot so that it does not work. • Safety Limited Speed function (SLS): This is a function to monitor the robot arm and the tools so that their speeds do not exceed specified limits. • Safely Limited Position function (SLP): This is a function to monitor whether positions of the robot arm and the hand are in a safe area.
