Parametering
The parameter assignments of the function block are satisfied by the determination of the integral GAIN and the limiting values YMAX and YMIN for output Y.
The limits YMAX and YMIN limit the output within the prescribed range. Therefore YMIN ≤ Y ≤ YMAX.
The markers QMAX and QMIN signal that the limits have been reached or the output signal is being limited.
Operating mode
There are three operating modes, which are selected via the inputs MAN and HALT:
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. The control output is, however, limited by YMAX and YMIN.
Halt
0
1
The output Y will be held at the last calculated value.
Example
The input signal is integrated via the time. If there is a jump on input X the output increases (for positive X values) or decreases (for negative X values) according to a ramp function. Y is always between YMAX and YMIN; if Y is equal to YMAX or YMIN, this is shown accordingly in QMAX or QMIN.
It displays the integrator jump response:
