2.2.2 Stopping Time and Stopping Distance in the Safety System

Safe stopping time is the time required from when an emergency stop or protective device (i.e. internal or

external) is activated and motion stops. In this system, activating the emergency stop button will apply Cat.

1 safety stop. Activation of a safety function or external safety protective device will be a Cat. 2 stop. It may

be necessary for the user or the system integrator to take these stop times into consideration when

implementing risk reduction measures. The robot continues moving during this time, which can transmit

energy and present additional risk. Refer to Appendix C for stopping time and stopping distance.

A change management process should be in place listing known acceptable settings and potential hazards.

Changes are made in the permissions management function. The authorized user must log in with

administrator's privilege to set all levels of permissions appropriately. Cybersecurity measure should take

place when using a network connection. The Corporation is not liable for the possible harm caused by

malicious attacks or intrusion of the users' network to modify the permissions management system or

safety setup.

The SF0 Robot Stick ESTOP refers to the built-in Emergency Switch on the Robot Stick of the TM Robot

control box, and the SF1 User Connected ESTOP Input refers to the Emergency Stop Port on the control

box, which is applicable to connect additional emergency switches.

Refer to the table below for the stop category and the reaction of the fault detection of the safety functions.

The functions come with discrepancy detection to maintain safety when detecting conflicting signals from

the dual channel input. When a discrepancy occurs, the system will enter and lock in a safety status. To

resume from the safety status, first check the input wiring, correct it, and let the dual inputs open and close

again, to enable the robot to the resume status of the safety function. When any fault other than

discrepancy in the safety functions is detected, the system performs a Cat. 0 stop. When Cat. 0 stop occurs,

reboot the robot system to recover from Cat.0 stop status.
