P-1
Proportional band
(PID group 1)
0.1 to 999.9 % 5.0 0 Displayed if the control method
is PID control (CtrL = 1).
I-1
Integration time
(PID group 1)
0 to 9999 (0 = no integral operation)
(The decimal point position is
determined by “Integral time and
derivative time decimal point position”
(C23)).
120 0
D-1
Derivative time
(PID group 1)
0 to 9999 (0 = no derivative operation)
(The decimal point position is
determined by “Integral time and
derivative time decimal point position”
(C23)).

RE-1
Manual reset
(PID group 1)
−10.0 % to +110.0 % 50.0 0 Displayed if the control method
is PID control (CtrL = 1) and if
integration time (I-1) of the PID
group = 0.
OL-1
MV low limit
(PID group 1)
−10.0 % to +110.0 % 0.0 1 Displayed if either of the set of
conditions below is met
• The control method is PID
control (CtrL = 1), individual
PID heating/cooling control
is not used (C26 ≠ 1), and the
integration time (I-1) of the
PID group = 0
• The control method is PID
control (CtrL = 1), individual
PID heating/cooling control
is used (C26 = 1), and the
integration time (I-1) or the
integration time for cooling of
the PID group (I-1C) = 0
OH-1
MV high limit
(PID group 1)
−10.0 % to +110.0 % 100.0 1
P-1C
Cool-side
proportional band
(PID group 1)
0.1 to 999.9 % 5.0 0 Displayed if the control method
is PID control (CtrL = 1) and
individual PID heating/cooling
control is used (C26 = 1)
I-1C
