قربان سلام و روز خوش
شما انکودر هایدن هاین رو موجد دارید یا رکسروس؟
نویسنده سایت کنترل حرکت و تعیین موقعیت ایران –
جناب قائدی درود و روز به خیر
در واقع رکسروس شرکت سازنده موتور و درایو هست. سفارش تولید انکودر های خود را به هایدن هاین منتقل می کند و شرکت Heidenhain یه سری کد ها رو برای آن اختصاصی تولید میکند. کد پیش روی شما هم گویای همین مورد هست.
با تشکر از توجه شما
