Cooling Fan in Control Box Stopped

  • Hi. :help:

    All the time Tech Pendat is showing Control Fan in Control Box Stopped, when it showed for the first time the fan was not working, so I replaced but the warning never clear :wallbash:, some times is necessary shut down the controller in order to move the robot manually(I'm not shure if is due to this), but when is running on Automatic, have not problem.

    I will appreciate any commentary or suggestions.

  • This alarm occurs when one of the two fans is over the cpu fails

    These fans (Brushless DC Minebea 2410ML-05W-B70) have 24v, 0v and a detector which gives an output to indicate it works and is what causes the alarm

  • have tried this twice...

    once with XRC...replacing the fan solved the problem....

    but.... :hmmm: :hmmm: :hmmm:

    with my Nx100, i couldent (and have still not) solved the problem. I have replaced it with a brand new fan from MOTOMAN (and seen that it is running perfect) i guess that the input that is mesuring the rpm on the fan might be blown.

    after 8 hrs of continuesly running the robot stops, and i have to power off and power on the controller.....
