When using the safety PLC, enable the optional safety field
bus function.
WARNING
• Compared to the hard-wired signal, the output signal from the safety
PLC (optional) requires time to be transmitted to the machine safety
board (type: YSF21-E) to stop the manipulator. Therefore, to start
detecting the signal on the machine safety board is a little delayed.
When stopping the manipulator by the output signal from the safety
PLC, consider the delayed time and perform enough risk
assessment for the robot system.
