[Design Instructions]

! DANGER

• Install a safety circuit external to the PLC that keeps the entire system safe if there are problems with the external power supply or PLC. Not doing so may cause false output or malfunction, leading to accidents.

(1) Outside the PLC, construct mechanical damage preventing interlock circuits, e.g. emergency stop circuits, protective circuits, forward/reverse or other conflicting operation interlocking circuits, and upper and lower positioning limit switches.

(2) When the PLC detects either of the following problems, it will stop arithmetic operation and turn off all outputs in the case of (a). In the case of (b), it will stop arithmetic operation and hold or turn off all outputs according to the parameter setting.

(a) The overcurrent protection or overvoltage protection of the power supply module is activated.

(b) The self-diagnostic function of the PLC CPU has detected a fault such as the watchdog timer error.

In addition, all outputs may be turned on when there are problems undetectable by the PLC CPU, such as in the I/O controller. Build a fail-safe circuit or provide a mechanism externally of the PLC to operate the machine safely at such times. Refer to the CPU module user's manual for fail-safe circuit examples.

(3) Output could be left on or off when there is trouble in the output module's relays, transistors,

etc. So build an external monitoring circuit that will monitor any output signal that could lead

to a serious accident.

(4)

[Design Instructions]

! DANGER

• When overcurrent exceeding the rated load current or caused by a shorted load or the like flows in the output module for a long time, it may cause smoke or fire. To prevent this, configure an external safety circuit, such as fuses.

• Build a circuit that turns on the external power supply after the PLC power supply has been turned on. If the external power supply is turned on first, it could result in false output or malfunction.

• When there are communication problems with the data link, refer to the corresponding data link manual for the operating status of each station. Not doing so could result in false output or malfunction.

• When connecting a peripheral device to the CPU module or connecting a personal computer or the like to the intelligent function module to exercise control (data change) on the running PLC, configure up an interlock circuit in the sequence program to ensure that the whole system will always operate safely.

Also before exercising other control (program change, operating status change (status control)) on the running PLC, read the manual carefully and fully confirm safety.

Especially for the above control on the remote PLC from an external device, an immediate action may not be taken for PLC trouble due to a data communication fault.

In addition to configuring up the interlock circuit in the sequence program, corrective and other actions to be taken as a system for the occurrence of a data communication fault should be predetermined between the external device and PLC CPU.

! CAUTION

• Do not bundle the control wires or communication cables with the main circuit or power wires, or run them close to each other.

They should be run 100mm (3.94in.) or more away from each other.

Not doing so could result in noise that would cause malfunction.

• When the output module is used to control a lamp load, heater, solenoid valve or the like, large

current (approximately 10 times greater than the normal) may flow when the output is turned

from OFF to ON. Choose an output module having a sufficient rated current.

(5)

[Installation Instructions]

! CAUTION

• Use the PLC in an environment that meets the general specifications contained in this manual.

Using this PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.

• Hold down the module-loading lever at the module bottom, and securely insert the module-fixing hook into the fixing hole in the base unit. Incorrect loading of the module can cause a

malfunction, failure or drop.

When using the PLC in the environment of much vibration, tighten the module with a screw.

Tighten the screw in the specified torque range. Undertightening can cause a drop, short circuit or malfunction. Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or module.

• When installing extension cables, be sure that the base unit and the extension module connectors are installed correctly.

After installation, check them for looseness.

Poor connections could cause an input or output failure.

• Securely load the memory card into the memory card loading connector.

After installation, check for lifting.

Poor connections could cause an operation fault.

• Completely turn off the external power supply before loading or unloading the module. Not doing so could result in damage to the product.

• Do not directly touch the module's conductive parts or electronic components.

Touching the conductive parts could cause an operation failure or give damage to the module.

[Wiring Instructions]

! DANGER

• Completely turn off the external power supply before starting wiring. Not doing so could result in electric shock or damage to the product.

• When turning on the power supply or starting operation after wiring work, always mount the product with the supplied terminal cover.

Not doing so could result in electric shock.

(6)

[Wiring Instructions]

! CAUTION

• Always ground the FG and LG terminals to the protective ground conductor. Not doing so could result in electric shock or malfunction.

• Before wiring the module, confirm the rated voltage and terminal layout of the product.

Connecting a power supply that is different from the rating or incorrectly wiring the product could result in fire or failure.

• External connectors should be crimped or pressure-welded with the specified tools, or correctly soldered. Imperfect connections could result in short circuit, fires or malfunction.

• Tighten the terminal screws in the specified torque range.

Undertightening could result in short circuit, fire or malfunction.

Overtightening could cause damage to the screws and/or the module, resulting in drop, short circuit or malfunction.

• Be careful not to allow foreign matter such as chips and wire off-cuts to enter the module.

Foreign matter could cause fire, failure, or malfunction.

• The module has an ingress prevention label on its top to prevent foreign matter, such as wire offcuts, from entering the module during wiring.

Do not peel this label during wiring.

Before starting system operation, be sure to peel this label because of heat dissipation.

• Install our PLC in a control panel for use.

Wire the main power supply to the power supply module installed in a control panel through a distribution terminal block.

Furthermore, the wiring and replacement of a power supply module have to be performed by a maintenance worker who acquainted with shock protection.

(For the wiring methods, refer to the QCPU User's Manual (Hardware Design, Maintenance and Inspection).)

[Startup/Maintenance Instructions]

! DANGER

• Do not touch the terminals while power is on.

Doing so could cause electric shock.

• Correctly connect the battery. Do not charge, disassemble, heat, place in fire, short circuit, or solder the battery.

Mishandling of the battery can cause heat generation, burst or ignition which could result in injury or fire.

• Switch off all phases of the externally supplied power used in the system when cleaning the module or retightening the terminal or module mounting screws.

Not doing so could result in electric shock.

Undertightening of terminal screws can cause a short circuit or malfunction.

Overtightening of screws can cause damages to the screws and/or the module, resulting in

fallout, short circuits, or malfunction.

(7)

[Startup/Maintenance Instructions]

! CAUTION

• The online operations conducted for the running CPU module by connecting a peripheral device (especially program modification, forced output, operating status change) should be performed after you have read the manual carefully read and fully confirmed safety.

1 GENERAL SPECIFICATIONS AND PRECAUTIONS FOR USE OF I/O MODULE

1. GENERAL SPECIFICATIONS MODULES AND PRECAUTIONS FOR USE OF I/O MODULE

This chapter describes the general specifications and precautions for use of I/O module.

1.1 General Specifications

Refer to the following manual for the general specifications of the I/O modules.

• QCPU User's Manual (Hardware Design/Maintenance and Inspection)

1.2 Precautions for Use 1.2.1 Input module

(1) The number of simultaneous on points of input module depends on its input voltage and ambient temperature.

Refer to the number of simultaneous on points shown on the specifications of each input module.

(2) Input modules may take in noise or the like as an input depending on the pulse width of a signal.

This pulse width has a value as listed below depending on the parameter-set response time. Set input response time while fully consider the operating environment.

Setting value of response time (ms)

Minimum value of pulse width where noise or the like may be

taken in as an input (ms)

1 0.3 5 3 10 6 20 12 70 45

For settings of the input response time, refer to Section 1.3.1.

(3) Read the following precautions carefully for use of the high-speed input modules (QX40H, QX70H, QX80H, and QX90H).

(a) When switching to the high-speed input, the specifications of the high-speed input modules and the input module QX40-S1 are identical. On the other hand, when switching to the interrupt input, the specifications of the high- speed input modules and the interrupt module QI60 are identical too.

Therefore, the specifications of the input module (QX40-S1) are construed as the specifications of the high-speed input module switched to the high-speed input. Similarly, the specifications of the interrupt module (QI60) indicated in the manuals other than this manual are construed as the specifications of the high-speed input module switched to the interrupt input.

*1: When selecting an improper module type, an error (error code: 2100) occurs.

*2: Setting the input response time with GX Developer is ignored.

(c) If the small number of value of input response time is set, the modules tend to have impact of noise. Ensure that the modules do not have impact of noise.

For the details of the measure against noise, refer to QCPU User’s manual (Hardware Design, Maintenance and Inspection).

(d) The high-speed input modules connected with electric appliance such as relays may load a chattering as a signal.

(e) Select a cable whose length is three meters or less, when using the high- speed input module as a CE-compatible product.

1.2.2 Output module

(1) If an output module drives load, its maximum switching frequency must be on for one second or longer and off for one second or longer.

(2) If a counter or timer which has a DC-DC converter as a load is used with an output module, choosing an output module by its average current can cause a failure due to periodic inrush current at power-on or during operation.

To reduce the influence of inrush current for use of the above load, connect a resistor or an inductance to the load in series or use a module whose maximum load current is large.

(3) Fuses installed to an output module cannot be replaced.

(4) Fuses installed to an output module are to prevent external wiring from being burned in case that outputs of the module short.

Therefore, if the fuses became a failure due to other than a short-circuit, the output modules may not be protected.

POINT

(1) When using the module for the application in which the relay contact is frequently switched, the relay life span should be considered. Therefore, it is recommended to use a triac output module.

(2) The relay life curve shows the value based on actual use, which is not guaranteed. Therefore, make sure to allow for a margin of error.

The relay life span differs according to the specifications as follows:

• Rated switching voltage, current load 100 thousand times

• 200VAC 1.5A, 240VAC 1A (COS =0.7) 100 thousand times

• 200VAC 0.4A, 240VAC 0.3A (COS =0.7) 300 thousand times

• 200VAC 1A, 240VAC 0.5A (COS =0.35) 100 thousand times

• 200VAC 0.3A, 240VAC 0.15A (COS =0.35) 300 thousand times

• 24VDC 1A, 100VDC 0.1A (L/R=7ms) 100 thousand times

• 24VDC 0.3A, 100VDC 0.03A (L/R=7ms) 300 thousand times

(21)

MELSEC-Q

1 GENERAL SPECIFICATIONS AND PRECAUTIONS FOR USE OF I/O MODULE

(b) Measures against inrush current

Relay life significantly varies depending on its load type the characteristics of its inrush current.

Take following measures since the inrush current may cause contact welding.

• In case of an increase in inrush current, select a load so that the inrush current will be within the rated current of the module.

• Connect the relay that can sustain inrush current outside the module.

1) Inductive load

Inrush current of inductive load may flow 20 times as large as the rated current depending on a load.

(c) Measures against back EMF

When inductive load such as a magnetic contactor and solenoid is shut off, high back EMF is generated between the contacts and arc discharge occurs.

Especially when the power factor is small, the life shortens due to arc discharge.

Therefore, take measures against arc discharge.

The following is four methods to protect a relay contact against back EMF.

• Capacitor + Resistor method (CR method)

• Diode method

• Diode + Zener diode method

• Varistor method

Circuit example Method for selecting elements Remarks

*1

Capacitor Resistor

Inductive load

Capacitor + Resistor method (CR method)

Capacitor Resistor

Inductive load

Refer to the following for constants of the capacitor and resistor. Note that the following values may differ depending on a nature of the load and a variation of characteristics.

• Capacitor 0.5 to 1 ( F) against contact current of 1A

• Resistor 0.5 to 1 ( ) against contact voltage of 1V

Use a capacitor whose withstanding voltage is 200 to 300V.

In AC circuit, use a capacitor having no polarity.

If a load is from a relay or solenoid, the recovery time delays.

A capacitor suppresses electric discharge while a contact is off, and a resistor restricts a flow of current while a contact is on.

*1: When using AC power, impedance of CR must be larger enough than that of the load. (prevention of a malfunction due to leak current from the CR)

Diode method

Diode ^Inductive_load

Use a diode whose reverse breakdown voltage is 10 times as large as the circuit voltage or more and whose forward current is equal to or more than the load current.

The recovery time is later than the CR method.

Diode + Zener

diode method ^Diode _Inductive

Zener Diode load

Use zener voltage for the zener diode equal to or more than the power supply voltage.

The diode method is effective when the recovery time is too late.

Circuit example Method for selecting elements Remarks

Varistor method

Varistor ^Inductiveload

Select a cut voltage (Vc) for the varistor to meet the following condition. Multiply the value by root two for use of AC power.

Vc Power supply voltage 1.5 (V)

Note that when selecting an element whose Vc is too high, its effect will weaken.

The recovery time delays slightly.

POINT

(1) Avoid providing a protection circuit as shown below.

Capacitor Inductive load

This circuit is greatly effective to an arc at shut-off.

However, since an electric charge has been accumulated in a capacitor while a contact is off, short circuit current of the capacitor flows while the contact is on, which tends to result in contact welding.

However, since a charge current of the capacitor flows while the contact is on, which tends to result in contact welding.

(2) A protection circuit must be provided so that it may be close to a load or contact (module). If their distance is far, the protection circuit cannot show its effect.

Provide the circuit so that their distance may be within 50cm (19.69 inch) (rough

standard).

1.2.3 I/O combined module

(1)I/O numbers of combined I/O modules

There are two types of combined I/O modules:

• Module using same I/O numbers for input and output

Since same number is used for input and output, the I/O numbers to be used can be saved.

• Module using sequential I/O numbers for input and output

Since I/O assignments are the same for A series, it is useful when replacing modules from those of A series.

The overload protection function and overheat protection function of the following modules are explained below.

(1) QY40P, QY40P-TS, QY41P, QY42P, QX41Y41P, QH42P

Function Description

Common

(Overload and overheat protection functions)

• If an overcurrent due to overload keeps flowing, heat is generated and the overheat protection function is activated.

• Each protection function is to protect the internal elements of the module, not to protect the external devices.

Overload protection function

• The overload protection function is activated in units of 1 point at 1A to 3A/point.

• The overload protection function returns to normal operation when the load becomes a rated load.

Overheat protection function

• The overheat protection function is activated in units of 1 point.

• The overheat protection function automatically returns to normal operation after heat reduces.

(2) QY81P

Function Description

Common

(Overload and overheat protection functions)

• If an overcurrent due to overload keeps flowing, heat is generated and the overheat protection function is activated.

• Each protection function is to protect the internal elements of the module, not to protect the external devices.

Overload protection function

• The overload protective function is activated in units of 1 point at 1A to 3A/point.

• The overload protective function returns to normal operation when the load becomes a rated load.

Overheat protection function

• The overheat protection function is activated in units of 2 points.

(It is activated in units of 2 points of Y0/Y1, Y2/Y3, ..., and when overheat protection is activated, 2 points of them are activated simultaneously. If an overheat status persists, heat is conducted, and which it may activate another overheat protection function.)

• If an output turns on at the activation of the overheat protection function, the actual output voltage oscillates between 0V and load voltage.

At the load voltage of 24V, the average voltage during oscillation is approx. 7V.

No oscillation occurs when the output is off at the activation of the overheat protection function.

To ensure that the output is turned off at the activation of the overheat protection function, use an external load that turns off at 7V or more.

• The overheat protective function automatically returns to normal operation after heat reduces.
