    Hello everyone

    Please I need help with the connection of an industrial servomotor and arduino, I am using a ACS606 controller, in leadshine brand, and a servo motor 200w to 3200 rpm, and I want to test engine performance, if anyone can give me a reference or diagram to connect, Thanks in advance.

    these are the images of the driver and the engine:

    Hello,
    Have you tried to get help directly from the website builder in the "Support" section ?
    Have you collected all the documentation available suppliers directly on the Net?
    Google ...or..!

    Bonjour,
    As tu essayé d'avoir de l'aide directement sur le site constructeur dans la rubrique "Support" ?.
    Avez-vous rassemblé toutes les documentations fournisseurs disponible directement sur le Net ?
    Google ... ou ... !

    Currently , if, I'm a little neophyte in handling servomotors with driver, and to send the signal Arduino, I confused the connection, and regular programming mini- servomotor is not equal, because this servomotor It works with an encoder

    I'm not sure you can connect arduino to this servo driver. It works like stepper.

    Perhaps another servo driver that accepts analog signal for positioning, or speed/direction control yes. Still you would need a signal conditioner to handle the -11v to +11v required for it.

    A little googling around might help you find what you need to adapt it for arduino.

    Thanks for replying, and if I search through google, but until now I have not found anything useful, and I would like, that this thread does not remain in doubt as it is becoming fashionable for the manufacture of simulators with higher degrees of freedom, Which can only be achieved with higher vp servomotors, but if someone can give us a hand we could maximize the use of SimTools.

    Perhaps if you search for "servo signal conditioner shield" you will come up with more relevant results.

    I know of no members on this site who are using AC servo motors in their sims - due to cost, complexity and even safety. I have plans to use them one day, but that does not help you now. Maybe try other sites where AC servo motors are used more often - Eg. CNCs.

    In fact there is a member, is working on a project, a 360-720 simulator, but does not give details of the project, and if it is true, the servomotors are very expensive, but it is good expand the possibilities.

    Controlling these servomotors is not so hard. All you need is an arduino with 0-5v signal output connected to a signal conditioner like this:
    http://www.controlgrips.com/electronicsdetails.php?productid=25
    The -10 to +10v analog signal will determine both the speed and direction of the servomotor. Now only thing is to add some limit sensor feedback to the arduino as well to turn the signal to 0v and block the signal to the limit direction. Otherwise it might be dangerous considering the power of these things.

    I wish I had the programming skills to write this up in code.

    I do have 3dof sim in progress that uses AC servos. These are getting cheaper all the time. I bought my 3pcs of 1kW servo+driver for around 1k€ + taxes. I do agree with safety. When you command servo to a position it does what ever it can to reach there. My 25cm lever has ~3000Nm constant and 9000Nm peak force (minus transmission losses ofc).. Slightly scary amount of power..

    Should i make my arduino/servo control circuit stuff to a guide or something?

    I wish you could show the connection of the Arduino with the servo motors, and the program that you loaded, so that many can start new projects with larger engines

    Here is a post where i already explained how to get arduino to control +-10V analog servos.
    https://www.xsimulator.net/community/posts/112012/

    In your case they are driven by step/dir just like stepper motors. Just connect those to your arduinos digital outputs (and step-/dir- to gnd ofc). Dir+ pin low/high = cw/ccw or vice versa. Pulse to pul+ pin makes servo move one step forward. I didnt check datasheet for that controller, but you may also need to pull ena+ high to enable servo driver.

    As an afternote i might release pcb designs and schematics or even a complete boards for arduino -> analog servo driving when i get my design finished. Atm i'm redesigning my boards and redoing all arduino code to add safety features, connectors for wiring and headers for future expandability.

    Thank you very much for your answer @Cartti, now if I can advance a little more my project, the idea is simpler than I expected, and good the plates would be a great contribution, I will be in expectations of your work.
