Google Translated: "You switch the animation using the blend pose as image.
When animation is connection is not a loop, the Index animation switched is played once, it will become a pause during playback ends when the connected node is switched again.
This is I want to animation playback start every time the Index is switched, but manually or will not and how that can be optionally run the animation start."
The State Machine can change before the animation is complete, so my thinking was that you could just create two states. 1 that performs the single cycle of your animation, and the 2 that idles. Both 1 and 2 can be interrupted by the same logic, and 2 takes over 1 in a prescribed amount of time.
Although, from your response, I think this is what you already tried.
