Fanuc Robot - Backup Battery Feedback?

    Hello All! This will be my first post to the forum.. Hopefully I can help as much as I ask for it :smiling_face:


    I would like to pick your brains and know if anyone is aware of a $variable that holds the backup battery voltage? Specifically the mechanical units 6V battery.


    The reason for this is I am setting up a trial robot using the EXOFF functionality of the E-Stop board. The software I have wrote looks at various conditions already to trigger the output as well as the batt alarm(UO) to inhibit the output.


    What I want to do is continuously monitor the battery voltage and send this to the PLC to display on the HMI screen I already have setup for this function. This will be a tool used to track voltage drop against power off time.


    Thank you in advance for any help in finding this information.


    Sean.

    Hi

    I called Fanuc USA on Friday, regarding a similar issue

    I asked if there is a way to find out how much life is left on the batteries and the answer was "Unfortunately there is nothing"

    I guess the alarm goes off electronically once it reach a certain value and that's it

    Retired but still helping

    I was hoping there was an overlooked variable that is monitored by the robots software to flag when <=3.6V. I will continue to look into it and let you know if I get anything.
