Al: Yes it expects a resolver. It's just me working mostly with encoders lately, and then that's what I plunk down. Sorry for the confusion. (Can I change the thread name?) Anyway forget the encoder, it's not there.
The motor is a Stromag with a standard resolver. I connected it using the docs. And I am sure that the excitation winding is going to the right place using an ohmmeter (it has a lower resistance). I also tried swapping polarities in case the two brands use different naming. Although it should be a standard, or am I wrong here?
Looking through the motor doc's I may have wrongly specified it as a 6pole while the doc indicate it may be a 4-pole. But it's fuzzy on that point (and in German) so I have to reread it tomorrow. I guess that would confuse the drive enough if wrong.
The bright side is I'll never need a crossword puzzle or a Rubiks Cube as long as I have a drive and a motor that's not in the list of known motors. :-) |
