with absolute value encoder)
Note
For a rigid mechanical coupling between the master and slave axes, it
is not permissible that P0179 is set to 2 if the slave drive is equipped
with an absolute value encoder. Otherwise, the slave drive would
position (in absolute terms) to the position specified in P0160.
Master and slave drive with absolute value encoder.
For master and slave drive with absolute value encoder, passive
referencing is not practical, as the axes have been adjusted corre-
sponding to Chapter 6.2.7 (Adjustment for absolute measuring sys-
tems).
