Looks like these drives can accept either Step/Dir or Analogue input so your choice of controller varied but would really need to see a proper manual to be 100% sure.
As you say it is for a lathe then that narrows down the choice a bit as you will need to get a controller that supports threading.
How does your turret work? does it require a lot of I/O, if so then maybe look at the CSMIO/IP-A (analogue +/- 10v control) from CS-Lab in Poland.
