Yes the pulley ratio iis for the index so you need to leave at 1 if your index is not on the motor. If it had been on the motor then you would enter a ratio in that case.
I helped a friend set up his Avon lathe a while back, it was using a CSMIO controller which outputs 0-10v for the spindle. What we did was settle on what the top speed he wanted, 2000rpm. We then set that in spindle pulleys and then commanded S2000 and read what the spindle was actually doing. We then worked out the rough ratio of true to commanded and altered the Max Hz in the VFD to achieve the correct spindle speed, seems to work well.
