Figure 60 Assigning the Position to the Setpoint
16.13 Parameter Group: Controller (Optional)
The optional PID controller is used for controlling an external actual value (process variable) to a
setpoint using 0/4-20 mA signal by readjusting the actuator.

Function
0: disabled PID controller disabled
1: Position
The output of the PID controller corresponds
to the position setpoint of the actuator. The
positioning (tracking of the actual position to the
setpoint) is done by the positioner (see Section
18.12 ).
2: Speed
The output of the PID controller corresponds to
the change of the position setpoint (speed) of the
actuator. The positioning (tracking of the actual
position to the setpoint) is done by the positioner
(see Section 18.12 ).
P14.2
PID
controller
External
Setpoint
0: Fixed
The PID controller uses an internal, fixed setpoint
(see parameter P14.3).
1: External
The PID controller uses the external setpoint. The
adjustment of this setpoint is done with the
parameters P13.2 and P13.3 (see Section 18.12 ).
