Restrictions
● If an encoder data set is used as encoder 1 in several drive data sets with different gears,
it is not possible to activate position tracking there. If an attempt is nevertheless made to
activate position tracking, fault F07555 (drive encoder: configuration position tracking) is
issued with fault value 03 hex.
Generally, it is checked whether the load gear is identical in all DDS in which this encoder
data set is used.
Load gear parameters p2504[D], p2505[D], p2720[D], p2721[D] and p2722[D] must be
identical in this case.
● If an encoder data set is used as a motor encoder with load position tracking in one DDS
and as an external encoder in another DDS, position tracking is restarted on changeover,
i.e. the behavior after changeover is the same as after a POWER ON.
● If position tracking is reset in one drive data set, this affects all drive data sets in which
this encoder data set is used.
● The maximum permissible movement of an axis in an inactive drive data sets is half the
encoder range (see p2722: tolerance window).
The table below describes the changeover behavior on transition from one DDS to another.
A changeover is always executed by DDS0.
