Analog input (block positions: A4, B4, A3, B3)
The PV can be measured by selecting the sensor type or range. For DC voltage
and DC current, PV and RSP scaling can be set. The input from a thermocouple
or resistance temperature detector can be used as the RSP. Linear approximation is
available.
Analog output (AO-C) (block positions: A2, B2, A1, B1)
The scaled MV can be output as current. Additionally, when PV, SP, or deviation is
selected for the output type, these values can also be scaled and output as current.
Linear approximation is available.
Voltage pulse output (V-P) (block positions: A2, B2, A1, B1)
The time proportioning output function set using the TP (time proportioning)
bank can be used. Linear approximation is available.
Motor drive output (MOTOR) (block position: B2)
The motor drive output function set using the PP (position proportioning) bank
can be used. Linear approximation is available.
Digital input (DI)
Change functions set using the DI bank, such as mode change, or SP group change,
can be used.
1-9
Chapter 1. Overview
Digital output (DO)
Output functions such as event output that are set using the DO bank, or the time
proportioning output function set using the TP (time proportioning) bank, can be
used. Linear approximation is available for time proportioning output.
CT (current transformer) input (block positions: A2, B2, A1, B1)
The current can be measured by the input from the CT. The control loop that
displays CT input can be set in the basic action bank.
VT (voltage transformer) input (block positions: A2, B2, A1, B1)
The voltage can be measured by the input from the VT. The control loop that
displays VT input can be set in the basic action bank. The resistance of the actuators
(heaters) calculated from the CT input and VT input can also be displayed in the
same control loop as VT input.

Chapter 1. Overview
Constant value operation: Process control uses the LSP or RSP.
Pattern operation: Process control uses the pattern SP (the SP is generated from the segment setting stored
in the measuring instrument).
RUN: Control execution status (the three statuses of RUN, RUN-HOLD, and RUN-END in
the case of pattern operation)
READY: Control stop status
AUTO: Automatic operation (This controller automatically determines the MV value.)
MANUAL: Manual operation (The MV value can be operated manually.)
LSP: Local SP (The control is performed based on the SP stored into the controller.)
RSP: Remote SP (The analog input from an external device is used as the SP.)
RUN-HOLD: Control status in which pattern progression is stopped
RUN-END: Control status in which pattern progression is stopped at the final point
AT: Auto tuning (The PID constants are set automatically using the limit cycle.)
Handling Precautions
• In the case of internal cascade control, it is not possible to switch into pattern
operation.
• With internal cascade control, the master side (Loop 1) in constant value
operation is fixed in LSP mode for RUN + AUTO modes. It cannot be switched
to the READY, MANUAL, or RSP mode.
• For the function to select RUN or READY at startup, a value stored in EEPROM,
RUN, or READY can be selected by setting "Loop1 Run/Ready at startup" to
"Loop4 Run/Ready at startup" in the basic action bank.
• If the version of the MAIN block firmware is earlier than 6.x.x (where x stands
for any number), there is no pattern operation function or Run/Ready at
startup selection function.

Handling Precautions
• After instrumentation wiring, check that the ferrules are inserted into the
terminal block correctly.
• When using ferrules, check for improper wire insertion.
• When using the AI-TWIN 2X0,5-8WH or AI-TWIN 2X0,75-8GY, pay special
attention to the terminal crimping orientation so that the insulation
sleeve does not interfere with adjacent terminals when the ferrules are
inserted into the terminal block.

Chapter 3. Wiring
Before wiring, installing, or removing this device, be sure to shut off the power supply.
Otherwise, there is a danger of electric shock.
Before handling the main unit and display unit or removing/inserting cables, touch a
grounded panel to discharge any static electricity.
If there is a risk of a power surge caused by lightning, use a surge absorber (surge protector).
Otherwise, there is a danger of fire or device failure.
Make sure that devices and equipment connected to this device have reinforced insulation or
double insulation suitable for their operating voltage and for this device's power.
Use this device with the provided power terminal block cover mounted. Otherwise, there is a
danger of electric shock.
Before touching terminals, shut off the power for the motor.
Attach ferrules with insulating sleeves to the wires for the MOTOR block. Do not use ferrules
without insulating sleeves. Use ferrules with insulating sleeves even when using a single wire.
Otherwise, there is a danger of electric shock.
Insert ferrules into the terminal block until the terminal part of the ferrule does not stick out.
Connect potentiometer (100 to 2500 Ω) wires to the terminals for motor feedback (terminals 4
to 6). If signal wires other than wires for the potentiometer are connected, the device may be
damaged. Make sure that the wiring is correct.

Grounding
• Before touching the power input terminal box, shut off the input power.
• The applicable crimp terminal for power input is a crimp terminal for M4
(8.5 mm or less wide), and the proper tightening torque is 1.4 N·m.
• Do not connect three or more crimp terminals to the same terminal screw.
• After completing the work, be sure to mount the cover on the power input
terminal block.
• There is a notch in the cover of the power terminal block to prevent slippage
of the cover.
Use the frame ground terminal to ground this device only. Do not connect the
ground wire from other devices.

3-8
Handling Precautions
• The DI/DO is general input/output. Use the DI/DO with the parameters set. By
default every DI/DO is set to DI.
• To use as DI:
• Gold contacts, etc., suitable for turning a microcurrent ON/OFF should
be used for the no-voltage make contacts. To handle the terminal current
during short-circuit and the open terminal voltage of this device, use
contacts with surplus minimum open/close capacity.
• When a semiconductor is used as a no-voltage make contact, use a
semiconductor whose voltage at both contact ends when the contact
is ON satisfies the allowable ON residual voltage. Additionally, use a
semiconductor whose OFF-state leakage current is within the allowable
limits.
• To use as DO or time proportional output:
• Pay attention to the polarity of the external power supply. Reverse
polarity connection may cause breakage.
• An overcurrent protection circuit is incorporated. If an overcurrent is
detected, the DO is forced OFF and an alarm is generated. The status of
the loads is checked every 5 seconds after overcurrent has been detected.
When the overcurrent status is canceled, the DO is restored automatically.

Handling Precautions
• Connect a terminating resistor (120 Ω, 1/2 W) to both ends of the
communication line. Do not connect a terminating resistor to the middle part
of the communication line.
• To connect two terminals together such as SG, use a crimp terminal without
an insulation sleeve.
• Be sure to connect the SG terminals to each other. Failure to do so might cause
unreliable communication.
• If equipment controller devices that do not allow connection of a terminating
resistor (such as Azbil Corporation's SDC15/25/26/35/36 and DMC10) are
included in the transmission line, do not connect any terminating resistor to
the external or communication lines of the C7G.
• The frame ground should be connected to only one end of the shielded cable,
not to both ends.

• Use shielded cables for input wiring.
• When a thermocouple is used for the input, take appropriate measures so that
no terminals are exposed to moving air. Failure to do so may result in an error.
• Set a suitable sensor type for usage. If the setting is incorrect, it will not be
possible to measure the PV correctly, and a hazardous situation could result,
such as a constant 100 % control output.

Sampling cycle
Configuration is possible for any range type of thermocouple, resistance
temperature detector, DC voltage, or DC current.
Even if the number of decimal places for PV is changed, the decimal point position
for the linear scaling and LSP in the AI bank does not change.
The decimal point position is set so that the entire value does not exceed 5 digits.
Ex.: If there are 2 digits after the decimal point, 999.99 is displayed as "999.99"
Ex.: If there are 2 digits after the decimal point, 1000.00 is displayed as "1000.0"
This setting is common to all AI blocks. The sampling cycle can be changed as
necessary.
The update cycle of analog input and the execution cycle of control operation are
called the sampling cycle.

PID control initialization
When changing the LSP or switching SP groups, the manipulated variable (MV)
may be stuck at the low or high limit, the PV may be resistant to change, or the PV
may overshoot. PID control initialization is effective in preventing these problems.
It can be set for each control loop.

*1. If 0 (Automatic) is set
When the LSP value is changed or SP groups are switched, whether the PID control must be initialized or not is
determined automatically, and it is initialized only when necessary.
*2. If 1 (No initialization) is set
When the LSP value is changed or SP groups are switched, the PID control is not initialized. This is a useful setting if the
continuity of the manipulated variable (MV) is important when the LSP value is changed or SP groups are switched.
*3. If 2 (Initialize) is set
PID control is always initialized when the LSP value is changed or SP groups are switched. This is a useful setting if prompt
response (increase or decrease) of the manipulated variable (MV) to the relationship between PV and SP is important
when the LSP value is changed or SP groups are switched.

For example, if 5.0 (%/s) is set while the sampling cycle is 0.01 s, the MV change
is limited to a maximum of 0.05 %.
If 0 is set, there is no limit for MV change.

4 - 5 AT (Auto-tuning)
Up to four loops can be controlled individually. Use the AT function to set the PID constants automatically.
How to start
(1) Make sure that the PV (analog input) and the actuators (heater power, etc.) are
ready for control.
(2) Make sure that this device is in RUN mode on the 1-loop monitor screen. If it
is in READY mode, change the mode to RUN.
(3) Make sure that the device is in AUTO mode on the 1-loop monitor screen. If
the device is in MANUAL mode, change the mode to AUTO.
(4) On the 1-loop monitor screen, press the [] (mode) button, and press the
[START] button in "AUTO TUNING."
How to stop AT
Display while AT is running
Operation while AT is running
AT stops automatically after the PID constants have been set.
To stop AT while it is running, press the [STOP] button next to the AT graph on the
1-loop monitor screen. Alternatively, on the 1-loop monitor screen, press the []
(mode) button, and press the [STOP] button in "AUTO TUNING."
Also, AT can be stopped by switching the mode to READY or MANUAL.
While AT is running, the AUTO TUNING progress graph is displayed on the
monitor screen. After AT ends and the PID constant is obtained, the AUTO
TUNING progress graph disappears.
AT obtains the PID constants using the limit cycle.
(1) AT uses the limit cycle method to find the PID constants by making a 2:1
dividing point in the deviation between the SP and PV at the start of AT.
This point becomes the ON/OFF switching point for the MV (manipulated
variable).
(2) When it is determined that the limit cycle has stabilized, the PID constant is
changed, and AT ends.

AT abnormal end
If AT does not start after the AT start operation, or if AT stops without changing the
PID constants even though there was no AT stop operation, an AT abnormal end is
generated and the data of the corresponding loop among the standard bit codes for
"AT abnormal end" for loops 1 to 4 changes to 1.
Clearing an AT abnormal end
To clear an AT abnormal end, do one of the following.
• Make sure that AT is executable and then start it.
• Press the AUTO TUNING [FAIL] button on the mode menu screen, and press the
[CLEAR] button on the confirmation screen (see the figures below).
• Power the device off and back on.
Chapter 4. Functions
Handling Precautions
• Before starting AT, make the PV (analog input) and the actuators (heater
power, etc.) ready for control.
• If the control action is set to ON/OFF, AT cannot be started. Set the control
action to PID.
• For AT to start, there must be no PV (analog input) errors, and RUN mode,
AUTO mode, and fixed value output is not selected.
• While AT is running, if the mode is switched to READY or MANUAL, if fixed
value output is selected, or if a PV (analog input) error or a power failure
occurs, AT stops without changing the PID constants.
• If heating/cooling control is not used, the MV low/high limit during AT and the
PID constant MV low/high output will be assigned to the MV. Set so that the
largest possible common area for these two ranges is left.

• While AT is running, the MV turns on and off several times to execute the limit
cycle. ("Off" here refers to the fact that the MV is limited by the MV low limit
during AT and by the MV low limit, and the factory setting is 0 %. Also, "on"
refers to the fact that the MV is limited by the MV high limit during AT and by
the MV high limit, and the factory setting is 100 %.) If there is a problem with
this operation, do either of the following.
•
Set the MV low limit during AT and the MV high limit during AT to
appropriate values, and start AT.
•
Do not use AT but set the PID constants manually.
• When heating/cooling control is used, execute AT with both Heat MV and Cool
MV running. In the first half, the MV changes with the output low/high limit
during AT. In the second half, it changes in a somewhat narrow range.
• AT progress is displayed in a graph on the monitor screen.
• It may not be possible to obtain appropriate PID constants, depending on the
control target. In that case, set the PID constants manually.
• The MV ON/OFF switching point determined at the start of AT does not
change even if the SP is changed while AT is running.
• AT can only be started by either the master side or the slave side of the
internal cascade control. Master and slave cannot both start AT.
• If the version of the MAIN block firmware is earlier than 6.x.x (where x stands
for any number), there are no standard bit codes for AT abnormal end (Loops
1 to 4).
