Can anyone tell me why there is a Step +, Dir +, Enable +, and Step -, Dir -, Enable - on this drive? I have 3 of these drives and would like to connect them to a CNC4PC Parallel BOB Board. Any ideas would be greatly appreciated.
Opto-isolated inputs. Read the manual for how to connect. http://www.pacsci.com/support/docume...s/ma6410rv.pdf
