Rexroth's newest motors are the MS2N series. As you can see from the model info below, they can come equipped with legacy Hiperface SKS/SKM and SEK/SEL encoder options, or they can come with the new Hengstler ACURO Link encoders.
If you have a model using the legacy Hiperface encoder, then the TI-5747 can be used. The TI-3025 power cable still works with this newest series as well. Unfortunately we do not have support for the Hengstler AD37 ACURO Link encoders yet, but do have future plans to develop support. We have been using the Rexroth drives to better understand these new encoders. Rexroth is programming unique alignment into the encoder memory, just as before.
Here is a datasheet that we made using the Rexroth drive to document alignment info:
