Parametering
The parameter assignments of the function block are satisfied by the determination of the factor gain, and the values for dampening dmp, and natural frequency freq.
Dampening dmp and natural frequency freq must have positive values.
Output Y follows input X jumps in a dampened oscillation. The period of undampened oscillation is T = 1/freq. For dampening values dmp < 1 reference is made to a dampened oscillation. For dampening values ≥ 1 reference is made to non-resonant behavior (i.e. without oscillation); in this case the output follows the input in the same way as with 2 LAG function blocks, which are switched in series.
Operating modes
There are three operating mode selectable through the man and halt parameter inputs:
Operating mode
man
halt
Meaning
Automatic
0
0
The function block operates as described in "Parametering".
Manual mode
1
0 or 1
The manual value YMAN will be transmitted fixed to the output Y.
Halt
0
1
The output Y will be held at the last calculated value. The output will no longer be changed, but can be overwritten by the user.
