• SAFETY PRECAUTIONS •

(Always read these instructions before using this equipment.)

Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product. For the safety instructions of the programmable controller system, please read the CPU module User's Manual. In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

DANGER

CAUTION

Note that the !CAUTION level may lead to a serious consequence according to t he circumstances. Always follow the instructions of both levels because they are important to personal safety.

Please save this manual to make it accessible when required and always forw ard it to the end user.

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

[Design Precautions]

DANGER

• Do not write data into the "read-only area" in t he buffer me mory of the int elligent function module. In addition, do not turn on/off the "reserved" signals among the I/O signals transferred to/from the PLC CPU. Doing so can malfunction the PLC system.

• Depending on the malfunction of the external output transistor, there may be cases where the output is ON or OFF status. Install external monitoring circuitry for output signals that may lead to major accidents.

CAUTION

• Do not bunch the control wires or communication cables with the main circuit or power wires, or install them close to each other. They should be installed 100 mm(3.94 inch) or more from each other. Not doing so could result in noise that may cause malfunction.

A - 1 A - 1

[Installation Precautions]

CAUTION

• Use the PLC in an environment that meets the general specifications cont ained in the CP U User's Manual. Using this PLC in an environment outside the range of the general specificat ions may cause electric shock, fire, malfunction, and damage to or deterioration of the product.

• When installing the module, securely insert the module fixing tabs int o the mountin g holes of the base module while pressing the installation lever located at the bottom of the module downward. Improper installation may result in malfunction, breakdown or the module co ming loose and dropping. Securely fix the module with screws if it is subject to vibration during use.

• Tighten the screws within the range of specified torque. If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

• Switch all phases of the external power supply off when mounting or removing the modu le. Not ding so may cause electric shock or damage to the module. The system that uses the QnPHCPU allows y ou to change a module online. Not e that there are restrictions on the modules that can be changed online and each module has a predetermined changing procedure. For details, refer to the chapter of online module change in this manual.

• Do not directly touch the conductive area or electronic components of the module. Doing so may cause malfunction or failure in the module.

[Wiring Precautions]

CAUTION

• Be careful not to let foreign matters such as sawdust or wire chips get inside the module. They may cause fires, failure or malfunction.

• The top surface of the module is covered with protective film to prevent foreign objects such as cable offcuts from entering the module when wiring. Do not remove this film until the wiring is complete. Before operating the system, be sure to remove the film to provide adequate heat ventilation.

• Be sure to fix communication cables or power supply cables leading from the module by placing them in the duct or clamping them. Cables not placed in the duct or without clamping may hang or shift, allow ing them to be accidentally pulled, which may cause a module malfunctio n and cable da mage.

• Do not grab on the cable when removing the communication or power cable connected to the module. When disconnecting a cable without a connector, first loosen the screws on the part that is connected to the module. Pulling the cable when it is still connected to the module may cause damage to t he module or cable, or misoperation due to cable contact failure.

A - 2 A - 2

[Wiring Precautions]

DANGER

• Always ground the shielded cable for the PLC. There is a risk of electric shock or malfunction.

• When wiring, be sure to verify the rated voltage of the product as well as the terminal layout. Fire or failure may result if incorrect voltage is input or incorrect wiring is performed.

• Connecting terminals with incorrect voltage may result in malfunction or mechanica l failure.

[Startup/Maintenance Precautions]

CAUTION

• Do not disassemble or modify the module. Doing so could cause failure, malfunction, injury or fire.

• Switch all phases of the external power supply off when mounting or removing the modu le. Not doing so may cause failure or malfunction of the module. The system that uses the QnPHCPU allows y ou to change a module online. Not e that there are restrictions on the modules that can be changed online and each module has a predetermined changing procedure. For details, refer to the chapter of online module change in this manual.

• Do not touch the connector while the power is on. Doing so may cause malfunction.

• Switch all phases of the external power supply off when cleaning or retightening the terminal screws and module installation screws. Not doing so may cause failure or malfunction of the module. If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damages to the screws and/or the module, resulting in the module falling out, short circuits or malfunct ion.

• Always make sure to touch the grounded metal to discharge the electricity charged in the body , etc., before touching the module. Failure to do so may cause a failure or malfunctions of the module.

1 GENERAL DESCRIPTION

1.1 Features

The Q64TC has the following features.

(1) Optimum temperature adjustment contr ol (PID contr ol )

(a) The Q64TC exercises temperature adjustment control automatically by

merely setting the PID constants (proportional band (P), integral time (I), derivative time (D)) and temperature set value (set value: SV) necessary for PID operations. Therefore, no special instructions are needed to perform PID control.

(b) Using the auto tuning function enables the PID constants to be set

automatically by the Q64TC. Hence, you can use the equipment without being conscious of cumbersome PID operation expressions to find the PID constants.

(2) 4 loops on 1 module

The module provides a maximum of four loops at the same time for temperature adjustment control.

MELSEC-Q

(3) RFB limiter function

The RFB (Reset FeedBack) limiter suppresses overshooting which is liable to occur at a startup or when a temperature set value (SV) is increased.

(4) Sensor compensation function

By setting a sensor compensation value, the sensor compensation function eliminates a difference between a temperature process value (PV) and an actual temperature, if any.

(5) Connection of thermocouples compatible w ith JIS, IEC , N BS,

ASTM and DIN Standards

(a) The Q64TCTT(BW) accepts the following thermocouples compatible with the

JIS, IEC, NB S, ASTM an d DI N St an da r d s.

• JIS Standards : R, K, J, S, B, E, T • IEC Standards: R, K, J, S, B, E, T, N

• NBS Standards : PL II • ASTM Standards: W5re, W23re

• DIN Standards : U, L

(b) The Q64TCTT(BW) allows you to set the temperature measurement ranges

which meet the operating temperatures of the above thermocouples.

(6) Connection of Pt100 and JPt100 platinum temp er atur e-measur i ng

resistors

The Q64TCTT(BW) allows you to set the temperature measurement ranges which meet the operating temperatures of the Pt100 and JPt100.

(7) Choice of fine temperature measurement units a n d v ar i ous contr ol

temperature ranges

The temperature measurement unit of each loop can be set to 1°C or 0.1°C in Centigrade or to 1°F or 0.1°F in Fahrenheit, enabling you to choose appropriate resolution for control. Also, the controllable temperature range can be selected from 0.0 to 400.0°C (when K type thermocouple is used), 0.0 to 3000.0°C (when R type thermocouple is used) and others, enabling you to make adequate setting for the object to be con t roll e d.

(8) E2PROM for backing up set values

The set values in buffer memory can be stored into E2PROM for data backup. Using the test function of GX Developer to write data directly to the buffer memory, what i s requi r ed in a sequ en ce prog r a m is "LD minimum.

(9) Detection of disconnection

The Q64TCTTBW and Q64TCRTBW can detect the disconnection of a heater.

(3) PID control (simplified two-level response selection)

In general, when the P, I, and D constants to improve the "response to the setting" are set, the "response to the disturbance" degrades by the PID control. Conversely, when the P, I, and D constants to improve the "response to the disturbance" are set, the "response to the setting" degrades by the PID control. In the PID control (simplified two-level response selection) of this module, "fast", "normal", or "slow" can be selected for the "response to the setting" while the P, I, and D constants for better "response for the disturbance" are selected.

1.3 About the PID Operation

The Q64TC can perform PID control in process-value incomplete differentiation.

1.3.1 Operation method and formula

The PID control in process-value incomplete differentiation is an operation method which puts the first-order delay filter as the input for derivative control action, and performs PID operation with the error value (E) after deleting the high-frequency noise component.

(1) The algorithm of the PID control in process-value incomplete

differentiation is shown in Figur e 1.6.

1.3.2 The Q64TC actions

The Q64TC performs PID operations in reverse action and forward action.

(1) Reverse action

In a reverse action, the process value (PV) increases toward the set value (SV) as the manipulation value (MV) increases. The reverse action is effective for heat control.

(2) Forward action

In a forward action, the process value (PV) decreases toward the set value (SV) as the manipulation value (MV) increases. The forward action is effective for cooler control.

1.3.3 Proportional action (P-action)

(1) The proportional action is an action to obtain the manipulation value proportional to

the deviation (difference between set value and process value).

(2) With the proportional action, the relationship between the changes in the deviation

and manipulation value can be expressed in the following formula:

EMV =

where Kp is a proportional constant and is called the proportional gain.

(3) The proportional action for the step response when the error value is constant is

shown in Figure 1.8.

(4) The manipulation value changes between -5.0% and 105.0 %. As the Kp

increases, the manipulation value for the same error value becomes larger, and the corrective action becomes stron ger .

MELSEC-Q

(5) The proportional action will generate an offset (remaining deflection).

1.3.4 Integral action (I-action)

(1) The integral action is an action which continuously changes the manipulation value

to eliminate the deviation when there is an deviation. The offset produced by the proportional action can be eliminated.

(2) In the integral action, the time from the deviation occurrence until the manipulation

value of the integral action becomes that of the proportional control action is called the integral time, and is indicated by Ti.

(3) The integral action for the step response when the error value is constant is shown

in Figure 1.9.

(4) The integral action is used as a PI action in combination with the proportional

action, or PID action in combination with the proportional and derivative actions. The integral action cannot be used alone.

1.3.5 Derivative action (D-action)

(1) The derivative action adds the manipulation value proportional to the change speed

to eliminate error when an deviation occurs. The derivative control action can prevent the control target from changing significantly due to disturbance.

(2) In the derivative action, the time from the deviation occurrence until the

manipulation value of the derivative action becomes that of the proportional action is called the der iva ti ve ti me, and is in di cated by T

(3) The derivative action for the step response when the deviation is constant is shown

in Figure 1.10.

(4) The derivative action is used as a PD action in combination with the proportional

action, or PID action in combination with the proportional and integral actions. The derivative action cannot be used alone.

The RFB limiter function limits the PID operation result (manipulated value : MV) not to exceed the valid range by the integral control action when an error continues for a long time. With the RFB limiter function, if the PID operation result exceeds the upper/lower output limiter value, the amount exceeded is fed back to the integral value and the PID operation result is kept at the limit value.

3.2.4 Sensor compensation function (1) Sensor compensation function

The sensor compensation function compensates the difference between the measured temperature and actual temperature caused by measurement conditions.

(2) Sensor compensation value setting

When there is a difference between the measured temperature and actual temperature, the full-scale percentage (-50.00 to 50.00%) is set in the buffer memory for sensor compensation value setting (2D sensor compensation value. For example, when the input range is at -200°C to 200°C and there is a 2°C error, the full-scale is 400°C(200°C-(-200°C)=400°C). Therefore, 2/400 x 100 = 0.5% is set.("50" is set in the buffer memory.)

The Q64TC performs upscale processing on the channels where temperature sensors (thermocouples/platinum temperature-measuring resistors) are not connected. Hence, when a temperature sensor is not connected to the channel which will not exercise temperature control, the PV value is judged as higher than the temperature measurement range of the input range, and the "ALM" LED is lit by alert processing.

3.2.6 Forced PID control stop (1) Forced PID control stop

Forced PID control stop is a function to stop PID operations temporarily from the PLC CPU. The action to be taken by the Q64TC at a PID operation stop depends on the setting of the stop mode setting buffer memory (21

3.2.7 Heater disconnection detection function (supported only by Q64TCTTBW,

Q64TCRTBW)

(1) Heater disconnection detection function

(a) This is a function to check if there is a heater wire breakage using the

standard heater current value (load current value detected by the current sensor (CT)), when the transistor output is on.

(b) The heater disconnection detection function compares the current values of

standard heater and heater disconnection alert, and determines that there is a heater wire breakage when the current value of standard heater is below that of heater disconnection alert. However, when the transistor turned-on time is less than 0.5 seconds, the heater disconnection detection is not performed.

(2) Heater disconnection compensation function

(a) Heater disconnection compensation

When the heater voltage drops, the heater current decreases as well. The Q64TCTTBW, Q64TCRTBW heater disconnection detection measures the heater current and determines the heater disconnection. Therefore, when the heater voltage drops, there are possibilities that a false alarm may be set due to the voltage change. Therefore, the Q64TCTTBW, Q64TCRTBW compensates for a drop in heater current (heater breakage compensation) so that the drop in heater current does not activate the break detection.

MELSEC-Q

(b) Heater disconnection compensation method

The heater disconnection compensation calculates "the heater current for each channel" - "standard current," and the largest positive value is set as the compensation value. When there is no positive values, the value with the smallest negative value is used as the compensation value. The heater current for each channel is compensated with the compensation value and a heater disconnection is detected when the compensated value exceeds the specified heater disconnection detection setting value.

Example 1: When the difference from the standard current at each channel is: Channel 1: -2 %, Cha nn el 2: 5%, Channel 3: -1% , Cha nn el 4: - 1 7%, the compensation value becomes 5%. The heater disconnection detection is performed from the values after a 5% compensation: Channel 1: -7%, Channel 2: 0%, Channel 3: -6%, Channel 4: 22%. Thus, when the heater disconnection detection setting value is at 80%, only channel 4 is detected as disconnected.

• The heater-disconnection compensation function will not work if only one channel is used.

• The heater-disconnection compensation function will not work if only one channel is used to keep the heater on while the others are used to keep it off. The module may detect a disconnection even when the heater is not disconnected.

• The heater disconnection detection compensation value is up to 20%. Therefore, when there is a voltage drop by more than 40%, a disconnection is detected even with a 20% compensation.

3.2.8 Output off-time current error detection function (av ail able for Q64TC TTBW and Q64TCRTBW only)

(1) Using the reference heater current value (load current value detected by the

current sensor (CT)), this function checks for a transistor output off-time current error when the transistor output is off.

(2) The transistor output off-time current error detection function compares the

reference heater current value and the current value of the heater disconnection alert, and judges it as an output off-time current error if the reference heater current value is higher than the current value of the output off-time current alert. Note that output off-time current error detection will not be made if the transistor output off period is within 0.5 seconds.

3.2.9 Loop disconnection detection function

The loop disconnection detection function detects errors in the control system (control loop) caused by a load (heater) disconnection, external operation device (e.g. magnetic relay) fault, input disconnection and others. When the PID operation value has reached 100% or 0%, this function starts monitoring the variation of the process value per loop disconnection detection judgment time to detect a heater or input disconnection. (1) When the heater is disconnected, when the input is disconnected or shorted, or

when the external operation device contact does not turn on, it is judged as an error since the temperature will not rise despite the control output provided.

In this case, an alert is output if a temperature rise of 2°C or more is not observed within the preset loop disconnection detection judgment time after the control output is provided 100%.

3 - 12 3 - 12

3 SPECIFICATIONS

(2) When the input is disconnected or when the external operation device contact is

welded, it is judged as an error since the temperature will rise though the control output is not provided. In this case, an alert is output if a temperature fall of 2°C or more is not observed within the preset loop disconnection detection judgment time after the control output has dropped to 0%. (In either case, inverse operation will be performed for forward action: cooling control.)

POINT

(1) When not using the loop disconnection detection function, set the loop

disconnection detection judgment time to "0".

(2) Setting the loop disconnection detection dead band will not cause a loop

disconnection if there is no temperature variation of 2°C or more when the control output is provided 100% or 0% at the set value. (Refer to Section

3.5.32.)

When the process value (PV)/deviation is close to the alert set value, the alert status may alterna te w i th th e non- ale rt statu s du e to input instabi lity o r th e l i ke. Setting the alert dead band prevents the alert status and non-alert status from alternating with each other due to input instability or the like when the process value (PV)/deviation is near the alert set value. Example: When the dead band value is set to the upper limit input alert, the

system is placed in the alert status when the upper limit of the input rises to or above the alert set value. The system is put in the nonalert status when the upper limit falls below the alert dead band.

Operation is governed by the unused channel setting, setting/operation mode setting, PID continuation flag, forced stop command and CPU error stop-time control output setting. (Refer to Section 3.2.13.)

(a) Temperature judgment: A temperature is input from the temperature sensor to

check whether it is within the temperature measurement range of the input range setting.

(b) Alert judgment: Alert checks 1 to 4 in Section 3.5.4 are made.

POINT

The default value (initial value) of the stop mode is set to "monitor". Hence, the channel without a temperature sensor connected results in a sensor input disconnection and the "ALM" LED is lit. For the channel to which a temperature sensor is not connected, set "1 (unused)" to the unused channel setting buffer memory (3D

According to the controlled object to be used, choose the auto tuning mode from the "standard mode" and "fast response mode". The standard mode is compatible with almost all controlled objects.

(1) Standard mode

This mode is compatible with almost all controlled objects. This mode is especially effective for controlled objects which give an extremely slow response or which may be affected by noise or interference. For the controlled object where either the ON or OFF time during auto tuning is about only 10 seconds, slow-response (low-gain) PID constants may be calculated. In this case, fast-response PID constants can be calculated by executing auto tuning in the fast response mode.

(2) Fast response mode

This mode calculates faster-response (higher-gain) PID constants for the controlled object which gives a fast response where the ON or OFF time during auto tuning is about only 10 seconds. Note that the gains of the calculated PID constants may become so high that the control temperature (PV) may oscillate near the set value (SV). In this case, execute auto tuning in the standard mode.

4.4 Wiring

This section provides wiring instructions and module connection examples.

4.4.1 Wiring precautions

External wiring must be noise-resistant as one of the conditions to fully exhibit the Q64TC functions and configure a highly reliably system. The instructions given below should be followed in wiring.

(1) Use separate cables with the AC control circuit and Q64TC's external input

signals to avoid the influence of AC side surges and induction.

(2) Do not run the cables close t o , or bu ndl e t he m wi th , the mai n circuit and high-

voltage cables and the load cables from other than the PLC. Always keep temperature sensors at least 100mm(3.94inch) away from the main circuit cables and AC control circuit. Fully keep them away from high-voltage cables and circuits which include high frequencies, e.g. inverter load's main circuit. Failure to do so will make the cables susceptible to noise, surges and induction.

MELSEC-Q

(3) Ground the shield wires or shield cables to FG of the PLC. Note that it may be

better to establish a ground on the external side depending on the external noise conditions.

(4) When you want the equipment to conform with the EMC Directive/Low Voltage

Directive, refer to "Conformance with the EMC Directive and Low Voltage Directive" in this manual and carry out wiring.

MELSEC-Q

(3) About display screen errors while usi ng the intel lig ent function

module utility

There may be cases in which the screen will not properly display while the intelligent function module utility is being used, due to a lack of system resources. If this occurs, close the intelligent function module utility first, and then close GX Developer (program, comments, etc.) and other applications. Next, restart GX Developer and the intelligent function module utility.

(4) To start the intelligent function module utility

(a) In GX Developer, select "QCPU (Q mode)" for the PLC series and specify the

project. If anything other than "QCPU (Q mode)" is selected for the PLC series, or if no pro je ct i s spe ci fie d, th e i ntellig ent function module utility will not start.

(b) Multiple intelligent function module utilities can be started.

However, the [Open file]/[Save file] parameter operations of the intelligent function module can only be performed by a single intelligent function module utility. Other intelligent function module utilities can perform the [Monitor/test] operation only.

(5) How to switch screens when two or more intel l igent function

module utilities are started

When two or more intelligent function module utility screens cannot be displayed side by side, use the task bar to display the desired intelligent function module utility screen on top of other screens.

Example) Counting the number of parameter settings in the automatic refresh

setting

The number of settings in this one line is counted as one setting. The number of settings is not counted by columns. Add up all the setting items in this setting screen, then add them to the total for the other intelligent function modules to get a grand total.
