I believe that I'm having trouble understanding how to set an 8i20 up properly.
It is connected to a 2.5KW 200V AC servo which can take a maximum current of 44.5 amps. Maximum speed of 5000RPM. It is running a lathe spindle. I am able to get it to spin up but it seems a bit sluggish. I also would expect, when setting the current value to maximum output that I would see current-lim go true but it doesn't. NVMAXCURRENT = 3000 current-maxlim = 30 current-minlim = -30 current-scalemax = 1 8i20 voltage says 350 ~ 351 voltage drops to 340 while accelerating. I have 10 GA wires from the power supply to the 8i20 which are about 8" long. The power supply is an ELMO Tam-20/230 with a peak of 40A power output. I've tried to look for some documentation explaining exactly how those values work, but I can't seem to find it.
