2: PID-B (PV derivative)
0
Cnt.05 L.2.
Control range low limit -19999 to +32000 U 0 The decimal point position is
determined by the decimal point
positions for the loop PV/SV.
Cnt.06 L.2.
Control range high limit 1000
Cnt.07 L.2.
AT type 0: Normal (regular control characteristics)
1: Immediate response (control charac-
teristics for fast response to external
disturbance)
2: Stable (control characteristics that mini-
mize up/down PV fluctuation)
0
Cnt.08 L.2.
Heat/cool control dead zone -100.0 to +100.0 % 0.0
Cnt.09 L.2.
Initial output of PID control -10.0 to +110.0 % 0.0
Cnt. 10 L.2.
Abnormal PV definition 0: If a PV alarm (AL01 to AL06) occurs
1: If a PV1 alarm (AL01 or AL02) occurs
2: If a PV2/21 alarm (AL03 or AL04) occurs
3: If a PV22 alarm (AL05 or AL06) occurs
0 Cannot be set on the SDC45A/
46A/45R/46R.
Etd.0 1 L.2.
PID control initialization 0: Auto 1: Not initialized
2: Initialized (if SP value different from the
current value is input)
0
Etd.02 L.2.
Integration time/derivative
time decimal point position
0: No decimal point
1: 1 digit after decimal point
2: 2 digits after decimal point
0 Affected by the decimal point
positions for integral time and
derivative time.
Etd.03 L.2.
Output after AUTO • MANUAL
change
0: Bumpless transfer 1: Preset 0
Etd.04 L.2.
Preset MANUAL value -10.0 to +110.0 % 0.0 When the power is turned ON, if
the operation mode is MANUAL,
the MV is the preset MANUAL
value.

Heat/cool selection 0: Normal 1: Energy saving 0
Etd.08 L.2.
MV low limit at AT -10.0 to +110.0 % 0.0
Etd.09 L.2.
MV high limit at AT 100.0
Etd. 12 L.2.
Zone operation 0: Changed by SP value
1: Changed by PV value
0 When zone PID is used, set the
PID group selection priority to
"Zone PID function".
