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 proporti-
onal 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).
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 controller structure to take effect (the setting Xp = 0
is not normally used in practice).
