I have done a few myself and walked countless mechanics through the upgrade. The easiest way to do it, is to go through the old drive, write down what all the logic inputs, outputs and relay coils are set to. Copy the wiring terminal to terminal (You will have to get both manuals to see the conversion because the terminals are labeled differently) Also be sure to take note of the encoder wiring before removing it from the 600. Re-input your parameters and connect your wires and you should be good to go.
