DIGITAL INDUSTRIAL CONTROLLER
english
Function block 21: Manipulated variable limiting
This function block can be used to define the range in which the output variable of
controller 1 may vary.
Adjustable parameters:
COh:
Maximum value of the output variable
COl:
Minimum value of the output variable
Function block 22: Setting the setpoint SP2
Setting the set-point via the controller keyboard (set-point of the subordinate
controller for cascade regulation).
Function block 23: Filter at input 2
The filter can be used to attenuate interference signals superimposed on the
measured signal. The filter consists of a low pass filter of the first order (see
Functional Block 1).
Adjustable parameters:
Fg2:
Limiting frequency (- 3 dB) of the filter at input 2.
Function block 24: Root extraction at input 2
This function serves to extract the root of the measured signal at input 2 (see
Functional Block 2).
Function block 25: Scaling at input 2
Function corresponding to function block 3.
Adjustable parameters:
P2h:
High scaling value, which is assigned to the maximum current, voltage or
frequency value.
P2l:
Low scaling value, which is assigned to the minimum current, voltage or
frequency value:
