Hello I need help with tune-up AC servo motor.
I am working on retrofitting Bridge port type Chevalier vertical milling machine. I have all components for that project. My motor IG 34 is working with my amplifier. There are all products of Servo Dynamics. http://www.servodynamics.com/industrial.html The problem that I have is that I bought bigger AC servo motor HJ 130 http://www.servodynamics.com/HJ130.html type from Servo Dynamic (Made in England) and my old tune up from smaller AC servo motor IG-34 not fit bigger motor HJ 130. I expect that and tried used my old experience but it still not enough. I did set I, D and FFO to zero. P I set to 30. . FF1 was = 1. At this setting when I jog motor it jerk and I got Error massage. I slowly increased P to 60-80 and motor start jerk more smoothly. At some point motor start rattle and I heat E stop. At P-60 I found that when I jog motor, it don't responded for 10 second and after that very fast jerk and after Error massage came in. Should I slowly increase only P until motor start moves - respond to jogging and than start adjust FF1 or I need simultaneously adjust two or even three parameters? Thank you, Aram K
