CTRL
Control method 0: ON/OFF control
1: PID control
0 or 1 0 The initial value is 0 if control
output 1 is a relay output, and 1
otherwise.
AT.OL
MV low limit at AT −10.0 to +110.0 % 0.0 0 Displayed if the control method
is PID control (CtrL = 1).
AT.OH
MV high limit at AT −10.0 to +110.0 % 100.0 0
DIFF
ON/OFF control
differential
0 to 9999 U 5 0 Displayed if the control method
is ON/OFF control (CtrL = 0).
OFFs
ON/OFF control
operating point
offset
−1999 to +9999 U 0 2
FL
PV filter 0.0 to 120.0 s 0.0 0
RA
PV ratio 0.001 to 9.999 1.000 1
BI
PV bias −1999 to +9999 U 0 0
CYU
Time proportional
cycle unit 1
0: 1 s
1: Always 0.5 s*
1
2: Always 0.25 s*
1
3: Always 0.1 s*
1
0 2 Displayed if the conditions to
display time proportional cycle 1
(CY) are met and the output does
not include a relay output.
CY
Time proportional
cycle 1
5 to 120 s
(when the output includes a relay output)
1 to 120 s
(when the output does not include a
relay output)
10 or 2 0 Displayed if MV1 (time
proportional output, or time
proportional output for heating
in heating/cooling control) is set
for relay control output, voltage
pulse control output, or event
output in DO assignment.
The initial value is 2 if control
output 1 is a voltage pulse
output, and 10 otherwise.
TPO
Time proportional
minimum ON/OFF
time 1
Set value: 0
If either one of the conditions below
is true, 250 ms applies.
Otherwise, 1 ms applies.
• MV1 is set for relay control output
or event output in DO assignment.
• Time proportional cycle 1 is 10 s or
longer.
Set value: 1–250 ms
If MV1 is set for relay control output
or event output in DO assignment,
1–49: 50 ms applies.
50–250: The set value applies.
0 2 Same as time proportional
cycle1 (CY)
CYU2
Time proportional
cycle unit 2
0: 1 s
1: Always 0.5 s*
2
2: Always 0.25 s*
2
3: Always 0.1 s*
2
0 2 Displayed if the conditions to
display time proportional cycle
2 (CY2) are met and the output
does not include a relay output.
