TB6600 + general drive and driver matching question

[JAZZCNC]

Jazcnc thanks very much for the very informative post I've learnt a lot

Next daft question does anyone know what the actual difference is between the leadshine em806 drives and it's predecessor the am882 and also the dm870?

The first two appear to be the same (hence is there a diff paying extra for the new one when the old one is still being sold new) and the dm870 appears to not offer sensorless stall detection although that is only above 300 rpm which for a direct drive application is a bit fast in my plasma application. Is it worth it is there anything else different?

I've used all three series. The EM806 appears to give slightly smoother motors at lower speeds and gives slightly more torque at higher speeds so can tune motors that little bit more aggresive. The case is slightly larger and gives better cooling but Basicly the EM series are the same as AM series but with tweaked software. Put it this way the difference is that if I couldn't get the EM and only had the AM I'd take them. If I had the choice and was £5-10 difference I'd take the EM every time.

The DM series on the other hand don't have stall detect and the software isn't has advanced and it shows in the motor smoothness at slower speeds. I also noticed that the motors get hotter compared to AM/EM so don't think they manage the amps/resonance the same. Compared to the EM/AM I wasn't so impressed. Still very good drives but not quite as good.! On a lesser note the DM are also limted to 7A motors so no use for larger 34's.
