Dear all.

we have a simotics synchronous servo motor (simotics s-1fk7100-2AC71-1UG0). and reolver also connected with it. the problem is its resolver is not working and we found the resolver primary and secondary  winding  and reference winding  satisfactory. now only its interface card remain to checked we have another same motor with different rating. when we are replacing the resolver with each other the all drive showing not ready. any one know we are doing right thing or how to confirm its interface  card is ok or not. [snip]

thank
