Hope you guys are online.
Have a question about something going on with one of the sure servo units on a pull to position
using the .75kw servo motor, not exactly sure of the exact model, i am not in the office.
Have a routine so that when the machine is first turned on i use a plc output to tell the servo to home. The servo will start to home but when it gets to home it does stop on a home prox, but has a small jerk. i quickly set the servo up to do a tuning and i used the adaptive tuning, which involved setting one of the parameters up for adaptive tuning and then jogging the motor back and forth multiple times. This did help but still have the small jerk when it reaches the home prox. I called tech support and they actually suggested doing what i had already done but could tell they did not want to spend any time except to tell me to do it over and over.
Archie, in your application which mode of tuning did you perform or did you have to tune. To start with the motor would start to home and when it hit the home prox it would stop and then start jerking forward and backward and kept getting faster unitl the servo faulted out. After doing the tuning by jogging fwd and reverse a few times it got a lot better. I read about the manual tuning but did not quite understand all of it, was hoping you could just tell the servo to perform a auto tune and that would be it and not have to manually adjust parameters. not sure how that will work in the foreign plants we have. One thing i did do, is i did not remove the belt and load off of the motor since it was getting late. Is it better to remove the load and then do the tuning the way i described.
Thanks for any advice.
