Note
Flying referencing is not an active operating mode. It is superimposed by an active operating
mode.
In contrast to eference point approach, flying referencing can be carried out superimposed
by the machine process.
As standard, for flying referencing, measuring probe evaluation is used; when enabled, the
measuring probe is selected (p2510) and the edge evaluation (p2511) (in the factory setting,
measuring probe 1 is always the measuring probe, flank evaluation in the factory setting is
always the 0/1 edge).
Instructions for switching data sets
Using drive data set changeover (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 changeover 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.
