Setting resolution
Step SV : Refer to Section “1.2 Rated input” (p. 6).
Step time : 1 minute or 1 second
Status after power is restored: The control resumes from the point at which power
failure occurred.
(Progressing time error after power is restored: Max. 1 minute)
Controlling action
• PID control (with auto-tuning function)
• PI control (When derivative time is set to 0)
• PD control (When integral time is set to 0)
• P control (When both integral and derivative time are set to 0)
• ON/OFF control (When proportional band is set to 0 or 0.0)
Proportional band (P) : TC, RTD input without a decimal point,
0 to 1000 (2000 ) (Default: 10 )
TC, RTD input with a decimal point:
0.0 to 999.9 (999.9 )
DC input: 0.0 to 100.0%
Integral time (I) : 0 to 1000 sec (Off when set to 0) (Default: 200 sec)
Derivative time (D) : 0 to 300 sec (Off when set to 0) ) (Default: 50 sec)
Proportional cycle : 1 to 120 sec (Default: 30 sec for –R/M, 3 sec for –S/M,
Not available for –A/M)
Anti-reset windup (ARW) : 0 to 100% (Default: 50%)
ON/OFF hysteresis : 0.1 to 100.0 ( ) (Default: 1.0 )
Output high limit, low limit: 0 to 100% (DC current output: -5 to 105%)
(Default: Output high limit; 100%, Output low limit; 0%)
Control output (OUT)
Relay contact : 1a1b
Control capacity: 3A 250V AC (resistive load)
1A 250V AC (inductive load cos =0.4)
Electric life: 100,000 cycles
Non-contact voltage : For SSR drive

0
V DC maximum 40mA DC (short circuit protected)
Current : 4 to 20mA DC
Load resistance: Maximum 550
Alarm 1 (A1) and Alarm 2 (A2) output
The alarm action point is set by deviation from the SV or step SV (except Process
alarm). When the input goes outside the range, the output is turned ON or OFF
(for High/Low limit range alarm).
Alarm Energized (When Alarm output is turned ON, Alarm indicator lights, and
when Alarm output is turned OFF, the alarm indicator goes off) or De-energized
(When Alarm output is turned ON, Alarm indicator goes off, and when Alarm
output is turned OFF, the alarm indicator lights) can be selected by keypad
operation.
Setting accuracy : The same as the indication accuracy
Action : ON/OFF action
Hysteresis : 0.1 to 100.0 ( ) (Default value: 1.0 )
DC current, voltage input: 1 to 1000 (The placement of the
decimal point follows the selection.)
Output : Relay contact 1a
Control capacity: 3A 250V AC (resistive load)
1A 250V AC (inductive load cos =0.4)
Electric life: 100,000 cycles
