The mclr8 wire if touched will completely stop all function. Sometimes it's smooth others it's not . Brand New encoder, factory assembled cable. Thoughts on using the 7i90 and halscope to look at the waveforms??? And thoughts on termination for these unused leads? The mclr8 won't terminate to ground or it stops the whole works ( of course no waveform analysis yet ) And the u,v,w + floating on air don't seem to be a solid idea either but there are no positions to terminate them on the drive. I'm thinking it could be this encoder, I will try tomorrow to get waveforms. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] Locked rotor
Also , cui says setting alignment will always align with u , so I presume the logic is standard, a,b,c is to u,v,w so I'm presuming that the a should be + and the b - for this alignment , it's a 4 pole motor so it has 2 mechanical lock points 180 degrees apart , should it matter which one of these mechanical points it's aligned with? -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
[Emc-users] Locked rotor for alignment
Kollmorgen eb 404 Does anyone know what phases to energize for locked rotor alignment of this motor? I finally have my cui encoder and programming cables, I have aligned with phase a + phase b- and set encoder. I can make it turn but it is rough I don't think I have the right phase aligned. I have walked a,b,c wires to no avail. Also cui gives +u,v,w, as well as -u,v,w output , the amc b3040 drive only has input for - and literature says it should be - so o have the + pins floating I'm kinda amiff as to what to do with those.
