Condition 1 -
read values
The positioner is initialized.
Purpose 1 Read values
You can use the P0 and P100 parameters to read the values for the

measurement as determined during the automatic initialization. The
values of manually approached end positions are applicable for
manual initialization.
Condition 2 -
change values
● The positioner is initialized and in manual mode (MAN) or
automatic mode (AUT).
● The current position of the actuator is within the range -10% to
+10% of the lower endstop (P0).
● The current position of the actuator is within the range 90% to
110% of the upper endstop (P100).
