Hi guys wondering if anyone has any ideas here.
I have a heidanhain spindle motor that runs up to 10000 rpm and has a 5v sin cos encoder on it. I am currently controlling the motor with a schiender vfd. I am talking to the support engineers here in New Zealand about buying a encoder card so I can get better low down torque. If I run the card in full encoder closed loop control in the vfd I can get 200 percent of the torque right down to 0 rpm for 30 seconds or so which is pretty useful. I am currently just running the drive in Variable frequency control which rapidly looses torque at low rpm. Anyway they have a bunch of cards I can use but don't have a encoder card that is suitable for sin cos encoders. I have no trouble changing the encoder but am not sure if I can get a source of encoders that spin up to 10k rpm. Anyone have any suggestions? regards Andrew _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
