Caution: For rotating absolute encoders, when adjusting, a range is set up symmetrically around zero with half of the
encoder range, within which the position must be re-established after powering down/powering up. In this range, it
is only permissible that the encoder overflows.
After the adjustment has been completed, it must be guaranteed that the range is not exited. The reason for this is
that outside the range, there is no clear reference any longer between the encoder actual value and mechanical
system.
If the reference point (CI: p2598) lies in this range, then the position actual value is set when adjusting to the refer-
ence point. Otherwise, adjustment is canceled with F07443.
There is no overflow for linear absolute encoders. This means that after the adjustment, the position can be re-
established in the complete traversing range after powering down/powering up. When adjusting, the position actual
value is set to the reference point.
Note: The encoder adjustment is initiated with p2507 = 2. The status is displayed using the other values.
In order to permanently save the determined position offset (p2525) it must be saved in a non-volatile fashion
(p0971, p0977).
This adjustment can only be initiated for an absolute encoder.

Description: Sets the signal source for the function "activate reference mark search".
Index: [0] = Closed-loop position control

Notice: When activating the function "set position actual value" while the function "reference mark search" is activated, then
the function "reference mark search" is automatically de-activated.
Note: When the function module "basic positioner" (r0108.4 = 1) is activated, the following BICO interconnection is estab-
lished: BI: p2508[0] = r2684.0
The function can only be activated using a 0/1 signal if no reference function is active (r2526.2).
If "reference mark search" and "measuring probe evaluation" are simultaneously activated, then no function is acti-
vated and the actual function is interrupted.
