    Re: 3 DOF with AC motor project (Starting)

    In this test is only 2dof? It's only working on the two rear motors? The response time looks very good.
    Good work!!! :clap: :clap: :clap:

    It would be interesting to see how it behaves when it's tested to the limits (fast start followed by hard braking and high speed chicane).

    very nice work.

    Can you tell me what you use to slide under the platform, with the spring.

    tres beau travail.
    peux tu me dire ce que tu utilises pour faire la coulisse sous la platforme, avec le ressort.

    Sorry,
    They are two triangle shaped metal tube only and the bigger size used for the other to move inside.
    The round metal plate is used for holding the spring.
    I wish this help

    thank you for your help.

    I use the same system but with square tubes. but I have too much play, movement (not sure of the word in English) I'll test with the anti-rotation bar.

    j'utilise le meme systeme mais avec des tubes carré. mais j'ai trop de jeu (pas sure du mot en anglais) je vais tester avec la barre antirotation.

    Hi,
    I have some questions to better understand:

    what is the frequency setting on the drives?

    the value of output speed, output card thanos is variable or fixed?

    if you put a lot of speed, for example 100hrz the drives, you have not exceeded set? PID offset?

    thanks
    Nice simulator!;)
