Hi All,
I was looking at a bunch of leadshine products today. There is something I am just not getting. Although I do try to read about things, I have only every put together one stepper control system for a CNC machine. So I think there is something basic here that I am not understanding.
For example, if you look at the Leadshine DMA860E
http://www.leadshineusa.com/uploadfi.../dma860e_m.pdf
it says you can have "Input voltage 18-80VAC or 24-110VDC"
I tried and failed to find examples of people using AC input to run steppers with a Leadshine driver. The manual only talks about selecting an appropriate DC power supply, and I can't find any mention of connecting to AC power. Yet, it's right there in the specs.
So with this driver, I can use a step down transformer using normal AC single phase power (to get it in the correct range) and I don't need to use a DC power supply? This would be to drive a Nema34 4 wire stepper motor. Is this true? What am I not understanding?
If I can do this, how does this translate to an equivalent DC power? For example, would I get the same performance using 80 VAC single phase input as I would using 80 VDC input from a power supply?
