I am using AC brushless servo motor for my motion control system. So I have to use a third party drive together with NI's controller. I am wondering whether I have to use an UMI. I read drive advisor in NI's website and it said some third party drive can connect directly to NI's controller, some need UMI. Can anybody tell me what it depends? My drive is Baldor's product. It has enable, forward and reverse limit function. Only things is digital I/O is 24VDC. Is that ok if I use SSR backplane instead of UMI?
I would appreciate you very much if you have any opinion on it.
