My place is like 300km from Prague, so it's quite a distance. Thanks anyway! This machine is very crucial for production, so we've got to deal with it asap.
About the amplidynes - there are still 2 plano milling machines in our factory which use them! :) Actually I'm doing renovation of one of...
Oh, I believe traveling that far might be exhausting. I've been to Norway few years ago - worked as a picker. I traveled from Bergen to Fresvik over 3 hours and I really enjoyed the view and the stay! Yes, I'm from Poland. It seems we have poor translators or they don't think we've got to know...
Hello again, I'm 1 day late, cause we needed to do some testings. IR compensation worked surprisingly well so it was that simple... Unfortunately that wasn't even mention in polish language manual, so it seems for the future I have to read english manuals. Anyway, thanks for help!
Tbh I'm not sure if it's set to 0, but according to manual it should be. Autotune sets int gain, prop gain and discontinuity values so I guess IR comp is still 0%. I'll make sure on Monday. I'll post the result as soon as I check it. Fingers crossed! :)
Thanks alot. I'll try to do that and see if that helps. Hope the table won't stop anymore. What about setup parameters::speed loop::spd.prop.gain and spd.int.time? Are they worth looking at aswell? I'm going to work on Monday, so I want to prepare as many possible solution as I can.
I should do the shaky thing with an empty table, right? I just read the manual and there is a parameter called IR compensation. It's set to 0% by default. The speed drops by approx 7% under the load (from 56 to 52 mm/min). Should I put this value, or go with the higher one, let's say 20%
I have a problem with the table feed while machining. Speed feedback is taken from armature voltage measure. Settings: Nom motor volts, armature current and field current are written from the engine and are set to - 220V , 46A and 3.1A . Main curr . limit at 120%. The drive has been calibrated...
