YF-09
YF-12
Absolute
The values set for
YF-09 and YF-12
represent the
feedback level that will cause a Low PI Auxiliary
Feedback and High PI Auxiliary Feedback. You
can set these parameters as an absolute value.
Delta to Setpoint
When the left-most digit changes to a Δ (delta),
you can set the Low Feedback Level and High
Feedback Level relative to the setpoint.
The effective Low PI Auxiliary Feedback Level is
“
Setpoint -
YF-09
”
, and the effective High PI
Auxiliary Feedback Level is
“

When
Y1-01 = 3 [Multiplex Mode = Memobus Network]
and
YF-01 = 1
, a staged Lead drive will de-stage as
specified by minimum or maximum PI Auxiliary Feedback Level:
•
A staged Lead drive will de-stage when
U5-16 [PI Aux Ctrl Feedback]
is less than
YF-04 [PI Aux Control
Minimum Level]
for the time set in
YF-05 [PI Aux Control Sleep Delay Time]
.
•
A staged Lead drive will de-stage when
U5-16
is more than
YF-24 [PI Auxiliary Ctrl Maximum Level]
for the time
set in
YF-05
