Aram, 2 PID loops are ok to use, just a bit more difficult to tune. I use Yaskawa motors/drives with the m5i20 & 7i33. I have to tune the yaskawa drive and motor first with yaskawa software and get them running smoothly. Usually I tune them fairly 'soft', that is not very stiff (in velocity mode). Then I tune them with EMC. It can be a bit tricky, but patience pay off. The motor/drive tuning is very important!! Also, since there are more parameters, it is a good idea to 'write it down' so you don't go around in circles. Good luck.

Am i right? is 1.0 output units means i use only 1.0V out of 10V that system can output? does pic www.conceptmachinery.com/Sh12.jpg looks ok? thanks aram > Jon > > ---------------------------------------------------------------------- > --- This SF.Net email is sponsored by the Moblin Your Move Developer's > challenge Build the coolest Linux based applications with Moblin SDK & > win great prizes Grand prize is a trip for two to an Open Source event > anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users No virus found in this incoming message.
