hello,

is not clear what your problem is.

The SMC20 can be configured in sinamics as external encoder do.

This DO can now connect in simotion with the Technologyobject external encoder, a axis is not need.

Hello,

yoe need no drive.

Create external encoder in sinamic and simotion and then use the systemfunction in simotion for the external encoder is all you need.

what you mean with "can read the position"? is this a eror or what? Exactly this should the encoder do, read the postion of the connected hw encoder.

Regards

Christoph

this is because you don't have configured a encoder DO.

what you configured is as drive objext whicxh need a correct motor configuratio.

this alarm means that the configuration is not correct or not complete.

the other thing is that telegram 105 is wrong if you only need to use encodervalues.
