I just see two pictures and no video.
the F 0026 usually appear with other Drive faults (0100~0150) Sub Code of those faults are important and you can refer to Fault code of each Drive.
the number of faults appear first like shows "F 2" then shows " 0026" that means you have 2 error and fist one is 0026 for second one you should press up or down button on CPU.
That is why I said video will help because show these and also LEDs on CPU.
