I am not sure what you are going to do with this board, the CSMIO/IP-A does not have any step and direction output, the controller has a 0-10V output that goes to the spindle speed control. If you need isolation because the current spindle has no isolation, then you are better to just throw the spindle away and stick an inverter and ac motor in the system.

This is the board I am using, as recommended by i2i.

On the board, I need to provide 24V DC, straight forward, I take from my 24V PSU rails.


I then need to provide the 0-10V output to the old DC drive, check, 2 wires, sorted.


I then need to provide GND, STEP, DIR and Run / Enable.


From my CS Labs unit IP-A, I get an Analog Output.


So, looking at the image below, I take from pin 7 (Analog Out 0) and pin 20 (Gnd) - do these go to the GND and STEP inputs on the board?








What do I use for DIR And Run / Enable then? Are these from my CS Labs unit (24V switched outputs)?
