Yes - I use a Telemecanique ATV21HU30N4 3Kw flux vector drive on the lathe. Works with analogue voltage input or modbus. I'm using analogue with a simple breakout board and commanded speed to actual speed track near enough for me. For instance if I command S500 spindle actually does 510rpm, S1000 does 1000 rpm exactly.
