I got a new stepper driver and I am now seeing some conflicting information about input voltage.
From the online manual, it can take 18-80 VAC or 30-110 VDC. Info on that here: https://www.omc-stepperonline.com/download/DM860T.pdf
From the manual that came with the driver, it takes 18-80 VDC or 36-110 VAC, which is flipped.
So the question is, which one is right? If it actually takes 18-80 VAC, peak voltage would be about 112 volts (peak = RMS * sqrt(2)), which makes sense. But then most residential AC supply voltage is 110V, and the DM860I, which is the same drive without the ability to take AC input, takes 20-80 VDC input. Why would they make the same one that uses a non standard AC input voltage, that is the same as its DC input voltage?
Not sure which one to trust, im hoping someone has used them before and can tell me what worked for them.
