I am trying to retrofit a lathe that had an Anilam control that died. I have had some help from Tom K. He has been very helpful and patient. He asked that I ask further questions on the forum - so here I am. I have a test bench set up with a 3 phase motor connected to a freq. drive and a dc servo motor and spare drive to see if I can simulate results before tearing into the lathe. Tom has helped me get to the point of being able to command the spindle motor on and off and vary the speed. I am able to enable the servo motor and it holds in an oscillating position. I cannot get movement with the dac xxx commands. I thought I needed a c program before I could use dac commands to the servo motor like I had to for the spindle motor, but Tom's last instructions were to test to see if I could command the motor speeds and direction first before doing any c program ?

Thanks,
Scott
