SAFETY PRECAUTIONS
(Read these precautions before use.)
Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety in order to handle the product correctly.
This manual classifies the safety precautions into two categories: [ WARNING] and [ CAUTION].
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.
Depending on the circumstances, procedures indicated by [
It is important to follow all precautions for personal safety.
CAUTION] may also cause severe injury.
Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.
[DESIGN PRECAUTIONS]
WARNING
● Make sure to set up the following safety circuits outside the PLC to ensure safe system operation even during external power supply problems or PLC failure. Otherwise, malfunctions may cause serious accidents.
- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements (such as forward vs. reverse rotation), and an interlock circuit to prevent damage to the equipment at the upper and lower positioning limits.
- Note that when the CPU module detects an error, such as a watchdog timer error, during selfdiagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU module occurs in an input/output control block, output control may be disabled. External circuits and mechanisms should be designed to ensure safe machine operation in such a case.
- Note that the output current of the 24 V DC service power supply varies depending on the model and the absence/presence of extension modules. If an overload occurs, the voltage automatically drops, inputs in the PLC are disabled, and all outputs are turned off. External circuits and mechanisms should be designed to ensure safe machine operation in such a case.
- Note that when an error occurs in a relay or transistor of an output circuit, the output might stay on or off. For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe machine operation.
● Construct an interlock circuit in the program so that the whole system always operates on the safe side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program change, parameter change, forced output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.
● In an output circuit, when a load current exceeding the current rating or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.
● For the operating status of each station after a communication failure of the network, refer to relevant manuals for the network. Incorrect output or malfunction may result in an accident.

[DESIGN PRECAUTIONS]
CAUTION
● When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on. Take proper measures so that the flowing current does not exceed the value corresponding to the maximum load specification of the resistance load.
● After the CPU module is powered on or is reset, the time taken to enter the RUN status varies depending on the system configuration, parameter settings, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of this variation in time.
● Simultaneously turn on and off the power supplies of the CPU module and extension modules.
● If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned off. When the power supply is restored, it will automatically restart (when the RUN/STOP/RESET switch is on RUN side).
[INSTALLATION PRECAUTIONS]
WARNING
● Make sure to cut off all phases of the power supply externally before attempting installation or wiring work. Failure to do so may cause electric shock or damage to the product.

*1 The value listed above indicates the number of files stored in the root folder.
*2 Clock data is retained using the power accumulated in a large-capacity capacitor incorporated into the PLC. When voltage of the largecapacity capacitor drops, clock data is no longer accurately retained. The retention period of a fully charged capacitor (electricity is conducted across the PLC for at least 30 minutes) is 10 days (ambient temperature: 25 (77)). How long the capacitor can hold the data depends on the operating ambient temperature. When the operating ambient temperature is high, the holding period is short.

Precautions
Precautions when using CC-Link master (FX3U-16CCL-M) and AnyWireASLINK master (FX3U-128ASL-M) together
When using FX3U-16CCL-M and FX3U-128ASL-M together, connect FX3U-128ASL-M on the left side. In the FX5U CPU module, FX3U-16CCL-M parameters are set up by PLC program and will occupy up to 256 remote I/O points. Therefore, the remote I/O points of FX3U-128ASL-M that is connected to the right side may be less than 128 points when FX3U-16CCL-M is connected to the left side.
Ex.
When input/output points are 160 points and CC-Link master are 256 points: 512 points - 160 points - 256 points = 96 points
Remote I/O points of AnyWireASLINK master are 96 points or less.

When the total number of the number of input/output points (including occupied input/output points) and the number of remote
I/O points of FX3U-128ASL-M that is connected to the left side exceeds 256 points, the difference of 512 minus that total can be used as CC-Link remote I/O points.

Output Wiring
The output wiring of the CPU module and I/O modules is explained below.
Relay output
For output specifications of the CPU module, refer to Page 21 Output Specifications.
For output specifications of the I/O modules, refer to Page 136 Output specifications.
Product life of relay output contacts
The product life of relay output contacts varies considerably depending on the load type used.
Note that loads generating reverse electromotive force or rush current may cause poor contact or welding of contacts which may lead to considerable reduction of the contact product life.
■Inductive load
Inductive loads generate large reverse electromotive force between contacts at shutdown, which may cause arc discharge. At a fixed current consumption, as the power factor (phase between current and voltage) gets smaller, the arc energy gets larger.
The standard life of contacts used for inductive AC loads, such as general contactors and solenoid valves, is 500,000 operations at 20 VA.
The following table shows the approximate life of a relay based on the results of an operation life test.

The product life of relay contacts becomes considerably shorter than the above conditions when the rush overcurrent is shut down.
Please refer to the following measures regarding the inductive load.
Page 91 Contact protection circuit for inductive loads
Some types of inductive loads generate rush current 5 to 15 times the stationary current at activation. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load.
■Lamp load
Lamp loads generally generate rush current 10 to 15 times the stationary current. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load.
■Capacitive load
Capacitive loads can generate rush current 20 to 40 times the stationary current. Make sure that the rush current does not exceed the current corresponding to the maximum specified resistance load.
Capacitive loads such as capacitors may be present in electronic circuit loads including inverters.
■Resistance load
For maximum load specifications of resistance load, refer to the following.
For output specifications of the CPU module, refer to Page 21 Output Specifications.

■External power supply
Use an external power supply of 30 V DC or less or 240 V AC or less (250 V AC or less when the module does not comply with CE, UL, cUL standards) for loads.
■Insulation of circuit
The PLC internal circuit and external load circuits are electrically insulated between the output relay coil and contact.
The common terminal blocks are separated from one another.
■Display of operation
When power is applied to the output relay coil, the LED is lit, and the output contact is turned on.
■Response time
The response time of the output relay from when the power is applied to the coil until the output contact is turned on and from when the coil is shut off until the output contact is turned off is approx. 10 ms.
■Output current
At a circuit voltage of 240 V AC or less (250 V AC or less when the module does not comply with CE, UL, cUL standards), a resistance load of 2 A per point or an inductive load of 80 VA or less (100 V AC or 200 V AC) can be driven.
For the life of the contact for switching an inductive load, refer to Page 89 Inductive load.

Set the CPU module to the STOP status and turn on the power supply again.
When the ERR LED turns off, a watchdog timer error has probably occurred. Take any of the following measures.
• Review the program and avoid the maximum value (SD524, SD525) of the scan time exceeding the the scan time monitoring time setting value set by the parameter.
• Check that the input used for input interruption or pulse catch is not being abnormally turned on and off in one scan.
• Check that the frequency of the pulse input to the high-speed counter is within the specified range.
• Add some WDT instructions to the program and reset the watchdog timer several times in one scan.
Provide a different power supply to the CPU module.
If the ERR LED turns off, noise may have affected the module. Consider taking the following measures.
• Check the ground wiring, and reexamine the wiring route and installation location.
• Fit a noise filter onto the power supply line.

Caution for when analog products are used
It is recommended to perform the following when precision of measuring and control is required.
As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary cables (integral with sensors or actuators), these users should follow those manufacturers' installation requirements.
Mitsubishi Electric recommends that shielded cables be used. If no other EMC protection is provided, users may experience temporary loss of accuracy between +10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggests that if adequate EMC precautions are followed with general good EMC practice for the user's complete control system, users should expect normal errors as specified in this manual.
• Sensitive analog cables should not be laid in the same trunking or cable conduit as high voltage cabling. Where possible, users should run analog cables separately.
• Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth loops are accidentally created.
• When reading analog values, EMC induced errors can be smoothed out by averaging the readings. This can be achieved either through functions on the analog devices or through a user's program in the FX5U CPU module.
Perform the following when using the analog expansion adapter:
• Installation in Enclosure
Programmable controllers are open-type devices that must be installed and used within conductive control cabinets.
Please use the programmable controller while installed within a conductive shielded control cabinet. Installation within a control cabinet greatly affects the safety of the system and aids in shielding noise from the programmable controller.
• Control cabinet
- The control cabinet must be conductive.
- Ground the control cabinet with the thickest possible grounding cable.
- To ensure that there is electric contact between the control cabinet and its door, connect the cabinet and its doors with thick wires.
- In order to suppress the leakage of radio waves, the control cabinet structure must have minimal openings. Also, wrap the cable holes with a shielding cover or other shielding devices.
- The gap between the control cabinet and its door must be as small as possible by attaching EMI gaskets between them.
Shielding cover
Shielded cable
Wires *1

*1 These wires are used to improve the conductivity between the door and control cabinet.
• Cables
- Make sure to use shielded cables as cables pulled out of the control cabinet.
- Connect the shield such as shielded cables and shielding covers to the grounded control cabinet.
• It is possible that the accuracy temporarily fluctuates within
10 %.
Perform the following when using the FX5-4AD-ADP:
• Set the number of times of winding to “2 turns” within approximately 200 mm (7.87") from terminal block of the analog cable on the FX5-4AD-ADP side, and attach a ferrite core. (Ferrite core used in our test: E04SR401938 manufactured by SEIWA

For L1MEM-2GBSD and L1MEM-4GBSD, refer to the following.
(QCPU User's Manual(Hardware Design, Maintenance and Inspection)
Handling of the SD memory card
• Operational compatibility of the SD memory cards manufactured by Mitsubishi (NZ1MEM-2GBSD and NZ1MEM-4GBSD) with MELSEC iQ-F series CPU modules has been checked. Use of SD memory card other than a Mitsubishi SD memory card may result in loss of the data stored in the SD memory card, or problems such as system stop.
• When mounted in the CPU module, SD memory cards manufactured by Mitsubishi are compliant with IEC61131-2.
• The SDHC memory card can be used only with devices with an SDHC logo or whose user's manual lists an SDHC logo.
Note that SDHC cards cannot be used with devices that support only "SD" specifications.
• Turning off or resetting the CPU module or removing the SD memory card while the card is being accessed may corrupt the data in the SD memory card. Always turn off or reset the CPU module or remove the SD memory card after disabling access to the SD memory card. With SM606 (SD memory card forced disable instruction) and SM607 (SD memory card forced disable status flag), the SD memory card can be disabled and its usage status can be checked.
• It is recommended that important data be periodically backed up to CD, DVD, or other media.
Formatting
To use any SD memory card in the CPU module, the card must be formatted. In the initial state after purchase, the SD memory card is not formatted. Insert the SD memory card to a CPU module and format the SD memory card using the engineering tool before use. Do not format the SD memory card using the personal computer. (GX Works3 Operating
Manual)
APPENDIX
Appendix 4 SD Memory Card

Insertion and removal of the SD memory card
The following explains insertion and removal of the SD memory card.
Insertion procedure
Mount the SD memory card. Pay attention to the direction of the card and follow the procedure below.
1.
Insert the SD memory card (1) straight into the SD memory card slot.
Make sure that the notch of the card is directed downward. After
(1) mounting, check that the card is mounted completely. If the card is mounted incompletely, malfunctions may occur because of poor contact.
(2)
2.
The CARD LED (2) blinks until the SD memory card becomes available.
3.
The CARD LED turns on when the SD memory card is available.
4.
If the CARD LED dose not turn on even though the SD memory card is mounted, make sure that SM606 (forcibly stop using SD memory card instruction) and SM607 (forcibly stop using SD memory card flag) are
OFF by using engineering tools.
Removal procedure
(3)
1.
Press the SD memory card stop switch (1) for one second or more to stop access to the card. The CARD READY LED (2) blinks during the access stop operation, and then the LED is turned OFF when the operation is completed.
2.
Insert the SD memory card (3) once, and then pull it straight.
(1)
(2)
Precautions
• When mounting or removing the SD memory card while the power is ON, follow the above-mentioned procedure.
Otherwise, the data in the card may be broken.
• When removing the SD memory card which is being accessed by any function, the CARD LED is turned OFF after the access is completed. When the CARD LED is turned OFF depends on the accessing function.
• When SM605 (mount and remove memory card disabling flag) is ON, the CARD LED is not turned OFF even if the SD memory card stop switch is pressed. If the CARD LED is not turned OFF, turn ON SM606 (instruction of forcibly stop using
SD memory card) so that the SD memory card cannot be used.

Handling of Batteries and Devices with
Built-in Batteries in EU Member States
This section describes the precautions for disposing of waste batteries in EU member states and exporting batteries and/or devices with built-in batteries to EU member states.
Disposal precautions
In EU member states, there is a separate collection system for waste batteries.
Dispose of batteries properly at the local community waste collection/recycling center.
The symbol shown in the following figure is printed on the batteries and packaging of batteries and devices with built-in batteries. This symbol indicates that batteries need to be disposed of separately from other wastes.
This symbol is for EU member states only.
The symbol is specified in the new EU Battery Directive (2006/66/EC) Article 20 "Information for end-users" and Annex II.
Exportation precautions
The new EU Battery Directive (2006/66/EC) requires the following when marketing or exporting batteries and/or devices with built-in batteries to EU member states.
• To print the symbol on batteries, devices, or their packaging
• To explain the symbol in the manuals of the products
Labeling
To market or export batteries and/or devices with built-in batteries, which have no symbol, to EU member states, print the symbol shown in the figure above on the batteries, devices, or their packaging.
Explaining the symbol in the manuals
To export devices incorporating Mitsubishi programmable controller to EU member states, provide the latest manuals that include the explanation of the symbol. If no Mitsubishi manuals are provided, separately attach an explanatory note regarding the symbol to each manual of the devices.
The requirements apply to batteries and/or devices with built-in batteries manufactured before the enforcement date of the new EU Battery Directive (2006/66/EC).
