Hi marauder,
Do the drives accept +/- 10V Analog Velocity commands?
Do the drives output differential encoder signals?
If so, you would need to order KFLOP + Kanalog.
Its fairly straightforward to wire Kanalog's DAC outputs to the Drive inputs and the Drives encoder signals to Kanalog's encoder inputs.
You might look at some User wiring diagrams in our wiki.
