5.16.32 DR 23 - Controller Optimum Plus
By defining the Controller Optimum Plus parameter, a weight tolerance is defined
above the set weight within which the proportional controller should not control to
a finer degree.
A new control weighing is run if another correction of the controller is required.
A correction is required if the set-actual deviation is greater than the Controller
optimum plus/minus or than the tolerance definitions range TO1 or TU1.
5.16.33 DR 23 - Controller Optimum Minus
By defining the Controller Optimum Plus parameter, a weight tolerance is defined
below the set weight within which the proportional controller should not control to
a finer degree.
A new control weighing is run if another correction of the controller is required.
A correction is required if the set-actual deviation is greater than the Controller
optimum plus/minus or than the tolerance definitions range TO1 or TU1.
5.16.34 DR 23 - Set value for fine time
If the fine time controller has been activated (see controller type selection
then the desired duration can be set for the fine signal.
The fine time controller optimises the fine signal duration by setting the fine weight
and therefore the rough current shut-off point. The shut-off point is set so that the
actual duration of the fine signal in a controlled status corresponds with the defined
value. The control deviation is defined after the end of the fine dosing:
t
Diff
= t
Set
- t
Act
t
Diff
= Control difference (s)
t
Set
= Fine set time (s) (=Default value)
t
Act
= Fine actual time (s)
The set value for the fine time is defined by the user depending on the material
properties.
