Which motion command I have to use in this project ? Can someone give me an example project like this ? Best Regards, Vorapob Wind_Unwind.jpg× 1 / 1Show captionsShowing image 1 of 1 [/INST] Vorapob, your question is too general to answer. There is no one motion control command to run a winder. You haven't told us anything about the hardware you plan to use. Will this be using VFDs? Servo drives? One on each axis, or just on the winder? Speeds? Desired tension? How accurate does the tension have to be? Is there a load cell to monitor tension? Does this have to go in both directions? That's the tip of the iceberg. If you truly need to get such a machine running and are not already familiar with motion control, you're probably going to need to contract with a company that does have such skills. I do not often pitch my company's services but this is a case where I think I should. If you really need assistance, send a private message. I'll send you contact information and a rates sheet. No matter who you choose to assist, in order to have them be cost effective you must first write a sequence of operations for your machine, along with operational parameters (speeds, tensions, supply voltage, safety requirements, etc.). The more you write out first, before you even talk with an expert, the less it will cost you. The more time a contractor has to pull facts from you, the more it will cost. \\n </s>
