    3DOF
    Hello,
    I have a 3dof sim simtools simulator driven by an arduino and 4 engines 400w. I created my Simu with the simukit kit and tutorials found on the site. I would now like to replace these engines with cylinders. This will allow me to gain in precision, reliability but especially in deflection. The problem is that I have no idea how these electric cylinders are controlled ...

    I would like to use the material found on frex:
    SimMOTION-4
    DC24V24A Power Supply
    SCN6-060-200

    That said, I still ask myself a lot of questions ...

    Do I need other items? Does the simMotion-4 box connect directly to the PC or does it require an intermediate electronic component, like arduino or other?

    This case is it compatible with simtools?

    Is the 24v 24a supply sufficient for the 4 actuators?

    Have you ever made a 3dof Simu on 4 cylinders?

    Do you have tutorials to advise me?

    Could you help me realize the evolution of my simulator?

    Thx a lot

    En français:

    Bonjour,

    Je possède un simulateur 3dof piloté par simtools et animé grâce à un arduino et 4 moteurs 400w. J’ai créer mon Simu grâce au kit de simukit et les tuto trouvés sur le site. J’aimerai à présent remplacer ces moteurs par des vérins. Ceci me permettrai de gagner en précision, en fiabilité mais surtout en débattement. Le problème est que je n’ai pas la moindre idée de comment se commandent ces vérins électriques...

    J’aimerai utiliser le matériel trouvé sur frex :
    SimMOTION-4
    DC24V24A Power Supply
    SCN6-060-200

    Cela dit, je me pose encore plein de questions...

    Est ce que j’ai besoin d’autres éléments?

    Est ce que le boîtier simMotion-4 se connecte directement sur le PC ou faut-il un composant électronique intermédiaire, genre arduino ou autre?

    Ce boîtier est il compatible avec simtools?

    L’alimentation 24v 24a est elle suffisante pour les 4 actionneurs?

    Avez vous déjà réalisé un Simu 3dof sur 4 vérins?

    Avez vous des tutos à me conseiller?

    Pourriez m’aider à réaliser l’évolution de mon simulateur?

    Merci,
    À bientôt.

    SCN6-060-xxx is wrong one for motion simulator. It is high torque low speed, speed chrop off at 50mm/s. You need the SCN6-040-xxx, which can go beyond 200mm/s.

    Hello, thank you for your answers.
    @noorbeast: If I understand the SCN FAQ, I can't use the SimMotion-4 with Simtool is that right? I am obligated to use a USB-RS458 converter for each actuator or, since version 2.2 one converter for 2 actuators.
    Can I connect them to a USB switch?

    @joe extraknow : Ok thanks for the information, the website of Frex is not very explicit.
    What weight does the SCN6-40-xxx support?
    What's the difference with the SCN6-20-xxx?

    Does the selected power supply (DC24V24A) correspond to the desired use?

    What do you think of the evolution I want to make on my simu?

    Thank you

    Bonjour, Merci pour vos réponses.
    @noorbeast : Si je comprends bien la FAQ SCN, je ne peux pas utiliser le simMotion-4 avec simtool c'est bien ça? Je suis obligé d'utiliser un USB-RS458 converter par vérin ou depuis la version 2.2 1 converter pour 2 vérins.
    Est ce que je peux les connecter sur un switch USB?

    @joe extraknow : ok merci pour l'information, le site de frex n'est pas tres explicite.
    Quel poids supporte le SCN6-40-xxx?
    Quelle différence avec le SCN6-20-xxx?

    Est ce que l'alimentation choisie (DC24V24A) correspond à l'utilisation souhaitée?

    Que pensez-vous de l'évolution que je souhaite apporter à mon simulateur?

    Merci.

    the 40 means 40kgf or 88 lbf.
    So for 4 of them can support max load of ~350 lb. But you shall not target this load. Commonly this actuator is used for 2dof with a piovt point, plus a traction loss that gives you a 3dof system.

    If you buy from Frex, you shall get all the parts I think and ready to go...
    See the video (include 24v power supply, 485/usb converter, controller/drive, cables etc.)

    40Kg by actuator, it's too little for the use I want to make... My current simulator supports almost 100kg per engine and I was hoping to switch to 200kg by actuator... Can I use other equipment compatible with Simtool?

    I thought that the SCN6 were equivalent to the Prosimu's PRS200... I now understand the price difference.


    FR :

    40Kg par actionneur, c'est trop peu pour l'utilisation que je souhaite en faire... Mon simulateur actuel supporte quasiment 100Kg par moteur et j'espérais passer à 200kg par actionneur... Est ce que je peux utiliser d'autres équipements compatibles avec simtool?

    J'imaginais que les SCN6 étaient équivalents aux PRS200 de prosimu... je comprends maintenant la différence de tarif.

    Well, 200kgf (>400lb) actuator is very expensive. I think D-Box makes one like this, costs at least $4k each I believe. I see some folks in this forum DIY "such" actuator with a bigger motor. Particular interesting the ones used a large Stepper motor.
    Yes, the SimTool supports SCN interface.
