10.14.5 Selecting Feedback Input (Resistor/Current)
Description
10-26
In the estimating type, a traveling time required to fully open the valve from its fully-
closed position is set and valve positions are estimated according to the time consumed
for valve operation.
The valve position estimating type is used when the feedback input of valve positions
cannot be obtained.
(Wiring for feedback input is not necessary.)
The fully-opened side relay keeps ON-state when the output is 100%, and the fully-
closed side relay keeps ON-state when the output is 0%.
Operating Principles
In the estimating type, the valve position is obtained by calculating the virtual feedback
input based on the valve traveling time.
However, the virtual feedback input starts calculation from 50% at power-on.
