S3-13
(3226)
RUN
PI2 Control Low
Feedback Lvl
Sets the secondary PI low feedback detection level.
Note:
Parameters S3-04 [PI2 Control Unit Selection], S3-03 [PI2 Control Decimal Place
Pos], and S3-02 [PI2 Control Transducer Scale] set the unit, resolution, and upper
limit.

(0.0 - 25.5 s)
389
S3-15
(3228)
RUN
PI2 Control High
Feedback Lvl
Sets the secondary PI high feedback detection level.
Note:
Parameters S3-04 [PI2 Control Unit Selection], S3-03 [PI2 Control Decimal Place
Pos], and S3-02 [PI2 Control Transducer Scale] set the unit, resolution, and upper
limit.
100.00
(0.00 - 600.00)
389
S3-16
(3229)
RUN
PI2 Control High
Feedback Time
Sets the secondary PI high feedback detection delay time in seconds. 1.0 s
(0.0 - 25.5 s)
389
S3-17
(322A)
RUN
PI2 Control Feedback Det
Sel
Sets when the low and high feedback detection multifunction outputs (71h and 72h) for
PI2 Control are active.
0 : While PI2 Control Enabled
1 : Always
Note:
Feedback level detection compares PI2 Control Feedback from analog input H3-xx =
26 [MFAI Function Selection = PI2 Control Feedback] to these parameters:
• S3-13 [PI2 Control Low Feedback Lvl] for low feedback level detection
• S3-15 [PI2 Control High Feedback Lvl] for high feedback level detection
