8-2-3 Connection Example
Precautions for Correct Use
• Design programs for the safety controller so that the STO function is not canceled automati-
cally even when the emergency stop switch is released.
• Design programs for the safety controller so that the STO function is not canceled automati-
cally when a Servo Drive failure is detected through the EDM output.
The following connection examples show how to connect the safety inputs and the EDM output to the
safety controller.
Wire SF1 and SF2 to different safety outputs.
