Hello all!
First of all, I want to tell you this is my first post and don't blame me too much.
My question is related to the electrical part. I have used only industrial PLCs so far and no computer-controlled utilities.
My servo drivers mains power is 220V but the STEP/DIR inputs are having a common of 24VDC and they expect - at the corresponding STEP/DIR terminals. I have no experience but what I know is - computers have 12VDC and 5VDC terminals. Any ideas what is the best solution in this situation?
Once more, my servo drivers are from China so they require minus(-) for control. I saw it's easy to toggle active low/high in Mach3 but don't know how to do it with a 24VDC inputs of the servo system.
I understand the problem may be easy and discussed but I am new, as I said.
Thank in advance.
