11 Parameterization
Three-state controller
This controller has two outputs, which can be configured as continuous (analog output) or
switched (digital output). In both cases, the controller can be parameterized with P, PI, PD, or
PID transmission behavior. The proportional bands Xp1 and Xp2 must be greater than 0 for the
controller structure to take effect.
If Xp1 = 0 and Xp2 = 0, the behavior corresponds to the function of limit value monitoring with
switching differential Xd1 and Xd2, and contact spacing Xsh (working point Y0 = 0 %):
Three-step controller
This controller has two switched outputs and can be parameterized with PI or PID transmission
behavior. The proportional band Xp must be greater than 0 for the controller structure to take
effect.
The three-step controller is used for actuator drives with three switching statuses (actuator
open, closed, hold). If output level feedback is available, the active output is deactivated when
the output level limits are reached.
Continuous controller
This controller has a continuous output (analog output) and can be parameterized with P, PI,
PD, or PID transmission behavior. The proportional band Xp must be greater than 0 for the con-
troller structure to take effect (the setting Xp = 0 is normally not used in practice).
Position controller
This controller is a continuous controller with integrated position controller and two switched
outputs (digital outputs) with PI or PID transmission behavior.
The position controller is used for actuator drives with three switching statuses (actuator open,
closed, hold). Output level feedback is required.
