Hi, I am using an EATON Variable Frequency Drive in a lab setting and was having trouble connecting it directly to my PC.
I am using this VFD: https://www.eaton.com/us/en-us/skuPage.MMX12AA7D0F0-0.html
My first attempt was to take an ethernet cord, cut off on end, and try to plug the data twisted pairs into the VFD. I was wondering if this effort could still be a solution (I am new to modbus and VFDs in general) and if I was plugging the wrong pairs into the terminals. I am using a Cat 6 Ethernet Cable.
After doing a bit more research I have found that there are usb to RS485 cables available. I was wondering if this would be a better solution, though I would like to avoid purchasing more material if possible. https://www.mouser.com/ProductDetail/FTDI/USB-RS485-WE-1800-BT?qs=sGAEpiMZZMsgSGrx0WqTbGAkhvJAByZv is the specific cable I was looking at.
Finally, the final option I am considering, though it is the least preferable, is to get the interface card that the VFD manufacturer lists in the data sheet.
