hi i did use data from 2.5.4 for 2.6.4 - it just gives error. i did tune up servo-dynamics motor servo motors. problem with SEM motor. it did work ok with 2.5.4 and same PID does not work on 2.6.4 tune up logic works for servo-dynamics motor but not for SEM motor. i found this interesting -http://www.cnccookbook.com/CCServoTuning.htm
i did increase P to get oscillation-- can not get oscillation even when P 1000 i did increase amount for all error - deadband by 10 times to make easy for system to work. for now with SEM motor i get abrupt motion after which error. with P10 and D 0.8 i got oscillation but after 30 second it dissipated with 2.5.4 --P was 17 and D0.01- and it did work what abrupt motion shows -- need increase D and i did try it -- or reduce P because system not stable ?
