Yaskawa Ethernet Safety

    Looking for some input on how to utilize the safety signals to safely stop the robot when an operator needs to enter the cell. My understanding is that I need to use the SVOFF first then use S-SAFF to open the safety circuit and prevent robot movement until the safety circuit is closed again.

    Safety Signals

    SVOFF CAT1 (Turn Off Srv Pwr)

    SVOFF CAT0 (Turn Off Srv Pwr)

    S-SAFF (Safety Fence Open)

    S-EXESP (External E-Stop)

    How do you want to use this signals? (in PLC or directly from robot)

    This signals come on safety board terminal. (you can see a green terminal that is usually mounted on the door of controller.)

    You can connect your signals to this terminal. now these signals are jumped on the Green terminal, you must disconnect and connect those to your key and button.
