Yes, I have the Drive.exe; BTW it runs very nicely in Wine. Well, they are very nice servo drives... when they are working. I am having difficulties with that. Now I have 2 drives working and 2 drives are misbehaving: 1) I purchased spare servo drive on eBay. When I received it, it turned out that communication with PC is not working. In early spring I sent it to TGDrives to fix that. They fixed it (at least they say that they changed communications processor). Now I put the drive in machine, tried to configure it, but Drive application did not find it, so communication still not working. But it should, since it has not been used since I received it from CZ; 2) the other misbehaving drive is my usual case - I get F25 (commutation error) error, I swap 2 servo drives to determine, if the problem is in drive (it goes together with drive) or in cables/motors (should appear also on swapped drive). The problem turns out to be in servo drive, so I send it to TGDrives, they _do not_ find the problem, I pay 40EUR diagnostics fee, they send the drive back and it works. After some time some other of the three drives shows F25, I send it to TGDrives, they find nothing, send it back and the drive works. I have no idea, what is the cause for these F25 errors, maybe I have bad aura. Conclusion - those drives are great, when they are working. Unfortunately they have so much functionality inside, that there are so many things that can break/cause error. Since EMC needs almost nothing of that functionality, I thought that changing them to some simpler servo drive, like 8i20, would be the way to go. I have spent more than a year trying to get that machine up and running. I thought that I am very close to finish with all the work on mechanics and electronics, but now the servo issue is messing everything up. Probably I am simply lacking skill and experience with such a complicated electronics, I do not know, that is why I would like to go with something simplier. > I just fixed a setup with 5 of these animals on a SERCOS loop (and another 4 > Indramats) They worked very well once I had the > Sercos part nailed. > Dont know if customer would be interested to keep spares. Prob to much > money. My offer is 1000EUR for all four of them. I think that 250EUR/piece is very cheap, compared to eBay prices. For 300EUR/piece I can send all of them to TGDrives for diagnostics so that they can give their statement, if there is something to be fixed or if the drives are fine. That way the buyer would get qualified opinion from 3rd party about the condition of the drives. If You purchase them for 300EUR/piece, I do not care, for what price would You sell them to Your customer :)) Viesturs ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
