C35, KL-5056D & Bardac 1600i DC drive

[Fastest1]

I think I can control the internal relay of my Bardac 1600i drive (link to manual http://bardac.com/pages/support/dc_p...1ph_drv_v6.pdf) with the output of the C35. This would give me spindle control but only of on or off. Will the C35 output a 0-10v signal or 4-20mA loop? Wouldnt this allow speed control thru mach? I do believe the G540 could produce this. If the C35 cant is there an additional card to interface with it?
