The Position Adjust Output (PAO) object drives a floating/3-wire actuator that does not provide position feedback. The object estimates the position of an actuator and then uses overdrives to reduce the difference between actual and desired (Present Value (Appears as I1)) actuator position.
You can use the value of this object in logic and to monitor the status of hardware.
