Enabled/Disabled and the controller that has been set, the actual value
(X), the setpoint (W), the manipulated variable (Yw) and the position feedback signal (Yx) are
graphically represented as a bar graph.
Note
Only the internal setpoint can be set in this menu.
When the switch position is toggled from Automatic mode to Stop, the current manipu-
lated variable (Yw) of the controller is transferred. This only applies when operating as a
positioner.
If a position feedback signal is parametrised, the controller functions as a positioner.
If there is no position feedback signal parametrised, or if this sensor is faulty, the con-
troller functions as a 3-pos. stepping controller.
The 3-point controller functions as a PI controller.
An I part is a mandatory requirement.
If the softstart is activated, the status is shown by the Int. setpoint.
