Instructions for switching data sets
Using drive data set switching (DDS), motor data sets (p0186) and encoder data sets (p0187
to p0189) can be switched. The following table shows when the reference bit (r2684.11) or
the status of the adjustment with absolute encoders (p2507) is reset.
In the following cases, when a DDS switch takes place, the current actual position value
becomes invalid (p2521 = 0) and the reference point (r2684.11 = 0) is reset.
● The EDS that is effective for the position control changes.
● The encoder assignment changes (p2502).
● The mechanical relationships change (p2503...p2506)
With absolute encoders, the status of the adjustment (p2507) is also reset, if the same
absolute encoder is selected for the position control although the mechanical relationships
have changed (p2503 ... p2506).
In operating mode, an error message (F07494) is also generated.
The following table contains a few examples for data set switching. The initial data set is
always DDS0.

Note
Flying referencing is not an active operating mode. It is superimposed by an active
operating mode.
In contrast to searches for reference, flying referencing can be carried out superimposed
by the machine process.
The measurement probe evaluation during which the measurement probe (p2510) and
edge evaluation (p2511) are selected with enable is used as standard for flying
referencing (in the factory setting, measurement probe is always measurement probe 1
and edge evaluation is always the 0/1 edge).
