5.1 PID Control Data
Description
Sets the number of loops
for which PID operation
will be executed.
Sets the number of loops
for which single PID
operation will be
executed when the
multiple loops reaches
the sampling cycle time.
Selects the PID
operational expression
indicated in Section
3.1.2/Section 3.2.2. (

This constant expresses
) the magnitude of the
I
integral operation (I
operation) effect.
Increasing the integral
constant slows down the
manipulated value
change.
This constant expresses
) the magnitude of the
D
derivative operation (D
operation) effect.
Increasing the derivative
constant causes a
significant change in the
manipulated value even
with slight change of the
control objective.
Sets the degree of
filtering applied to the
process value.
The filtering effect
decreases as the value
gets closer to 0.
