In a double axis drive as well the first axis may have a 2nd "EC" encoder. Means:
- both axes always have the digital encoder interface present to allow the evaluation of AcuroLink encoders present at MS2N motors
- both axes have an additional multi-encoder interface for each axis if ordered with option "EC" at type code field 20 and 21
- 1st axis incorporates an additional multi-encoder interface if ordered with option "EC" at type code field 22 and 23
Only two of these encoders may be functional for each of these axes.
