If the reference point (CI: p2598) lies in this range, then the position actual value is set when adjusting to the
reference 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 switch-off/switch-on. 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) and the DDS number (p2733), they 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] = Position control
[1] = Encoder 1
[2] = Encoder 2
[3] = Reserved
Dependency: Refer to: p0490, p2502, p2509, r2684
Refer to: A07495
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 deactivated.
Note: 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
activated and the actual function is interrupted.

0/1 signal:
The function "activate measuring probe evaluation" is started.

Dependency: Refer to: p0488, p0489, p0490, p2502, p2508, p2510, p2511, p2517, p2518
Refer to: A07495
Notice: When the "set position actual value" is activated while the function "measuring probe evaluation" is activated, then
the function "measuring probe evaluation" is automatically deactivated.
Note: 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
activated and the actual function is interrupted.
