Wiring
Caution
To prevent electric shock, always turn off and disconnect this device
from the power supply before starting wiring.
Do not touch wired terminals or charged parts with your hands while
the power is supplied.
Pay attention to the following points when performing wiring:
Check that the wiring is free from mistakes according to "1-5 Rear Terminal
Arrangement Diagrams."
Use crimped terminals that accommodate an M3 screw and that have a width of 6.2
mm or less.
For thermocouple input, use a compensation wire compatible with the type of thermocouple.
For RTD input, the resistance of a single lead wire must be 10Ω or less and the three
wires must have the same resistance.
The input signal lead must not be passed along the same conduit or duct as that for
high-voltage power lines.
Shield wiring (single point grounding) is effective against static induction noise.
Short interval twisted pair wiring is effective against electromagnetic induction noise.
When wiring, use wire or cable (minimum 1 mm2 cross-sectional area) of 600 V
grade PVC insulated wire or equivalent wire having the same rating.
For wiring the ground, ground the ground terminal with the earth resistance at less
than 100 and with wire 2 mm2 or thicker.
Two earth terminals are provided, each connected internally. One is for the ground
connection, and the other is for connecting the shield of the signal lead. Do not use
the earth terminals for crossover wiring of the power system ground lead.
If this device is considered as being susceptible to noise caused by the power supply,
attach a noise filter to prevent abnormal functioning.
Install a noise filter onto a grounded panel, and make the wire connecting the noise
filter output and the power supply terminal on this controller as short as possible.

Note
When an extremely large remote ratio is set, the range that can be used as the
remote signal input becomes extremely narrow, and when an extremely small
remote ratio is set, the range of the remote SV becomes extremely narrow.
Applying a large bias further narrows the usable range. Take the above points

Proportional Band (P)
"Proportional band" refers to the range in which the size of the control output changes in
proportion to the difference (deviation) between the measured value (PV) and the set
value (SV).
Here, set the percentage (%) that control output is made to change with respect to the
measuring range.
When a wide proportional band is set, the change in the control output with respect to
deviation decreases, and the offset (constant deviation) increases.
When a narrow proportional band is set, the change in the control output increases, and
the offset decreases. If too narrow a proportional band is set, hunting (vibration) occurs,
and action becomes similar to that of ON-OFF control.
When P=OFF is set, control becomes ON-OFF control, and auto tuning cannot be
executed.

When a long integral time is set, offset correction action is weak, and it takes a long time

becomes. However, if too short an integral time is set, hunting (vibration) occurs, and
action becomes similar to that of ON-OFF control.

the longer a derivative time is set, the stronger derivative action becomes. However, if

Automatic setting of MR
When auto tuning is executed, the manual reset (MR) value is computed and
automatically set.
During PID control, the MR is used as the target load ratio in PID initial computation.
For this reason, to reduce overshoot when the power is turned ON or STBY is switched
to EXE, set a small MR value to lower this target load ratio.
When auto tuning is performed by PID control on this device, the load ratio is calculated
so that offset is decreased even if there is no I action, and the value corresponding to the
manual reset is automatically set.
This function enables control results superior to those enabled by regular PID control to
be obtained.

Event Logic Operations
This function performs logic operations on inputs from two DIs and outputs the result to
EVENT/DO.
This function sets a logic gate to each of the two inputs, performs logic operation (AND,
OR or XOR) on these inputs, and outputs the result to EVENT/DO.
Events that can be selected are EV1 to EV3 and DO1 to DO3.

DI input signals are handled as they are as input logic signals.
Inverter
DI input signals are reversed and the result is handled as the input logic
signal.
Flip-flop
DI input signals are reversed and the result is handled as the input logic
signal each time that the assigned DI turns ON.
When DI turns ON, that ON state is sustained even if it turns OFF later.
In this case, the input logic turns OFF when DI is ON next time.
The DI monitor indicator lights when an input signal is input. When Gate is set to
INV, logic becomes Logic 1 when DI input is OFF, and Logic 0 when DI input is
ON. For this reason, the logic state becomes the reverse of the DI monitor.
When Gate is set to FF, the logic state is alternately switched between Logic 1
and Logic 0 each time that DI is input. For this reason, the logic state can be
confirmed on the logic operation monitor.
When DI assignment is set to None, no action is performed even if the DI signal
is input.
Timers/Counters
With this timer/counter function, DI is taken as input and DO is taken as output.
When input is generated, and after it passes preset time/preset counts, DO is output.
The timers and counters operate regardless of the control action of this device, and
output a one-shot pulse of one second.
Only DO4 and DO5 can be assigned for the timers and counters.

Auto Tuning
Executing and Stopping Auto Tuning
Select execution/stop of PID auto tuning (AT).
During execution of auto tuning, the optimum PID constants are calculated according to
the limit cycle method, and those values are used to automatically perform control action.
During execution of auto tuning, hunting caused by the limit cycle occurs near the SV
value.
Hunting near the SV value can be prevented by setting the auto tuning point to perform
auto tuning when the value leaves the SV value.
For details on setting this auto tuning point, see "10-10 Auto Tuning Point."

15-10 Tuning Functions
This section describes the PID constant tuning functions.
Adjustment of PID (P: proportional band, I: integral time, D: derivative time) that are used
in PID control is generally referred to as "tuning."
The SR23 Series supports the following two PID constant tuning methods:
1. Auto tuning (AT)
2. Self tuning
Caution
As the SR23 is a high-precision, multi-function controller, use of the
auto tuning (AT) function is recommended as optimum PID constants
can be obtained more easily than by self tuning.
On the following types of control targets, set tuning sometimes does
not function normally, inappropriate PID constants are calculated and
set, and the optimum control result is not obtained. For this reason, do
not use self tuning:
Control targets that have cyclical external disturbance
Control target with extremely short or long dead band
When the measured value (PV value) contains noise and is
unstable
For two output specification, the tuning mode is fixed to Auto Tuning.
15-10-1
Auto tuning (AT)
System operation in Auto tuning
SR23 auto tuning is performed by the limit cycle method.
By this method, the control output is turned ON/OFF, to measure the amplitude and

Note
Auto tuning sometimes is not performed correctly when the measured value (PV)
contains noise and is unstable. Either stabilize the measurement input, or use a
PV filter, for example, to stabilize the measured value before executing auto
tuning.
When the output limiter is used, set the output limiter before execution of auto
tuning. Note however, that control output operates between 0% to 100% (ONOFF) regardless of the output limiter when output is contact output or SSR drive
voltage output.
With some control targets, optimum PID constants are sometimes not obtained. If
this happens, correcting the PID constants obtained by auto tuning may provide
better results.
15 OPERATIONS DURING CONTROL
15-10-2
89
Self tuning
Self tuning is a function provided for performing tuning more easily than auto tuning. Self
tuning is executed after tuning conditions are automatically judged. Two methods are
provided on the SR23 for self tuning:
1. Self tuning: step response (St)
2. Self tuning: hunting suppression (Hu)
These self tuning modes cannot be specified by users, as these are automatically
selected by SR23.
(1)
Self tuning: by step response (St)
With self tuning by step response, timing is automatically performed by the step
response method and PID constants are set by measuring fluctuations in the measured
value (PV) when a fixed deviation and stable control output are being output, for
example, when the power is turned ON, standby mode (STBY) is changed to execution
(STBY OFF), or the setting value (SV) is changed.
Step response tuning
SV
PV
St execution
Start PV
St complete
When self tuning by step response is started up, control computation is performed using
the preset PID constants, and when tuning ends successfully, control computation is
performed using the PID constants obtained and set by tuning.
Accordingly, when tuning is not to start up or is canceled, control computation will be
continued using the PID constants set so far.
Conditions for starting up Self tuning

Immediately after power ON
When standby (STBY) is changed to execution (STBY OFF)
When the SV value is changed

When the PV value causes a scale over (SO) error
When zone PID is set

When step output (error between control output before and after startup) is 10% or
less
Conditions for canceling Self tuning by the step response
When the following operations are performed during self tuning by the step response, or
conditions are satisfied, self tuning is canceled, and control is continued using the PID
constants that were previously set:
When the control characteristics (Reverse/Direct) are changed
When the output limiter is changed
When the control output is changed
* As control is performed using the PID constants that were set when self tuning was
set, when the proportional band is large, and the deviation between the set value
and the measured value is small, the control output will immediately fluctuate. For
this reason, tuning becomes more likely to be canceled.
When 10 hours have elapsed after tuning is started
When the measured value fluctuates due to noise, etc., and it is judged that
computation by the step response method is abnormal
Caution
When the following conditions are not observed in self tuning by step
response, accurate tuning results cannot be obtained, and inappropriate
PID constants sometimes are calculated and set:
The control target and control loop must be operating correctly.
The measured value (PV) must be in a stable state when self tuning is
started up. When measured values are fluctuating considerably,
inappropriate PID constants may be calculated by executing self tuning.
The power of control terminals such as heaters must be ON when self
tuning is started up.
If inappropriate PID constants are set, and stable control results cannot be
obtained by the above conditions, perform the following to remedy this:
Correct the PID constants obtained by self tuning.
Execute auto tuning (AT).

15 OPERATIONS DURING CONTROL
Tuning standby conditions
When the following conditions occur, operation stands by for new startup conditions to
be generated:
When the current fluctuation width attenuates (gets smaller) to 25% or less from the
previous fluctuation width
When the 5th fluctuation width attenuates (gets smaller) to 25% or less from the
initial fluctuation width
When the PID constants are changed
When the control characteristics (Reverse/Direct) are changed
When the output limiter is changed
The aim of hunting suppression tuning when hunting occurs is to suppress hunting that
occurs when the PID constants do not match the actual control target (e.g. small P, small
I, large D).
As the aim is to suppress vibration, when vibration is caused by cyclic external
disturbance, for example, the PID constants may be slightly corrected (e.g. larger P,
larger I), which might result in increased vibration.
If this happens, the PID constants must be adjusted by the following methods:
Reduce cyclic external disturbance.
Set up the PID constants by auto tuning (AT).
