Description: Sets the behavior of the position actual value preprocessing for the position controller for a DDS changeover.
Re p2519 = 1:
In the following cases, for a DDS changeover, the actual position actual value becomes invalid and the reference
point is reset:
- the EDS effective for the closed-loop position control changes.
- the encoder assignment changes (p2502).
- the mechanical relationships change (p2503 ... p2506).
- the direction of rotation changes (p1821).
For absolute encoders, the status of the adjustment (p2507) is also reset if the same absolute encoder remains
selected for the closed-loop position control, but the mechanical relationships or the direction of rotation have
changed.
In the operation state, in addition, a fault (F07494) is generated.
Notice: The remaining setting values are intended for expanded functionality.
Note: The behavior for a DDS changeover is determined using the value of p2519 in the target data set.
