Control Computation Specifications
(1) Combination of types of control and control
modes
• PID control
• ON/OFF control
• Heating and cooling control
(2) Control Computation Function
(a) The number of PID parameter groups
Four sets of PID parameters can be set.
(b) Selecting the PID parameter group
The following PID parameter groups can be selected.
• Segment PID
• Measured input zone PID
• Target setpoint zone PID
• Reached target setpoint zone PID
• Local PID
• Reference deviation
(c) Auto-tuning
• Tuning results can be selected from two options,
Normal or Stable.
• Tuning output limit can be set. (It cannot be used in
heating/cooling control.)
(d) “Super” function: Overshoot-suppressing function
(e) “Super 2” function: Hunting-suppressing function
(f) RESET preset output function
(g) Input ERROR preset output function
(h) MANUAL preset output function
(3) Operation Mode Switching
Operation
mode
switching
Start of program operation (PROG)
Stop of program operation (RESET)
Start of local-mode operation (LOCAL)
Start of remote-mode operation (REM)
Pause/cancel release of program operation (HOLD)
Advance of segment (ADV)
Automatic (AUTO)/Manual (MAN) switching
(4) Control Parameter Setting Range
Proportional band 0.1 to 999.9%
Integral time
1 to 6000 sec. or OFF (using manual
reset)
Derivative time 1 to 6000 sec. or OFF
ON/OFF control hysteresis
(one
or two hysteresis points)
0.0 to 100.0% of measured input
range width
Preset output value
-5.0 to 105.0% (however, 0 mA or less
cannot be output)
High/low output limiter
-5.0 to 105.0%
Low limit setpoint < high limit setpoint
Tight shut function
When manual control is carried out
with 4 to 20 mA output, control output
can be reduced to about 0 mA.
Rate-of-change limiter of
output
0.1 to 100.0%/sec., OFF
Output dead band
For heating and cooling control:
-100.0 to 50.0%
For position proportional control: 1.0
to 10.0%
