speed animation bond

[Magrinsi]

Hello, everyone.
I was trying to make an animation of a tipping tape using the ability to animate a tie of the stem of the linear actuator.
Unfortunately, I can't handle the speed of animation. ..any value I put in the voice "fast animation" does not change anything.... .

you must change the " specified value ".
The captions are a little crypto.
