SMC Networks IP8001 Series Operation Manual page 34

Operation setting: Set lower and upper limit based on actuator
operation position. Operate the same as
manual mode, and P value becomes set value
when it returned to upper directly by mode
button. Ex-factory default values are (431) =
0.0 %, and (432) = 100.0 %.
(431) and upper limit (432) can be set only by
conditions below. Unless the condition is
satisfied, check code 2 (CHE0002) is indicated
and upper limit or lower limit are set
automatically. See " ■ Check Code List" for
details.
Span to be set : "(432) - (431)" ≧ 60.0 %
(Ex) Select (200) = dir when
(430) = ACt, (431)=10.0 and (432) = 90.0

When this zero point / span setting is conducted, a position value
(P value) is shown with determination of the set span as 0-100%.
With the settings of (410) = vALu, (411) = 0.0, and (412) = 80.0, it
is reflected to each item as shown on Table 12. Suppose actuator
full stroke is 30mm as an example.

5: When zero / span is set while forced fully-close / fully-open (parameter
code:500) is ON, forced fully-close / fully-open is priotized, and
actuator stroke becomes 30mm.
