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 normal 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 self-

diagnosis, 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 machinery 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, transistor or triac 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 machinery operation in such a case.

● 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, forcible 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.

● To maintain the safety of the programmable controller system against unauthorized access from
external devices via the network, take appropriate measures. To maintain the safety against
unauthorized access via the Internet, take measures such as installing a firewall.

[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).

[PRÉCAUTIONS DE CONCEPTION]

AVERTISSEMENT

● Assurez-vous de configurer les circuits de sécurité suivants en dehors du contrôleur programmable
pour assurer un fonctionnement sûr du système, même pendant les problèmes d'alimentation externe
ou la panne du contrôleur programmable. Faute de quoi, des dysfonctionnements peuvent causer des
accidents graves.

- Configurez surtout ce qui suit : un circuit d'arrêt d'urgence, un circuit de protection, un circuit de

verrouillage pour les mouvements opposés (tels que la rotation normale ou inversée) et un circuit
de verrouillage (pour éviter d'endommager l'équipement aux niveaux supérieur et inférieur de
limites de positionnement).

- Notez que lorsque le module CPU détecte une erreur, telle qu'une erreur de minuteur de

surveillance, pendant l’auto-diagnostic, toutes les sorties sont désactivées. En outre, lorsqu'une
erreur qui ne peut pas être détectée par le module CPU se produit dans un bloc de contrôle E/S,
la commande de sortie peut être désactivée. Les circuits et mécanismes externes devraient être
conçus pour assurer un fonctionnement sûr des machines dans un tel cas.

- Notez que le courant de sortie de l'alimentation du service 24 V DC varie en fonction du modèle et

de l'absence/présence des modules d'extension. Si une surcharge survient, la tension diminue
automatiquement, les entrées dans le contrôleur programmable sont désactivées et toutes les
sorties sont désactivées. Les circuits et les mécanismes externes devraient être conçus pour
assurer un fonctionnement sûr des machines dans un tel cas.

- Notez que lorsqu'une erreur se produit dans un relais, un transistor ou un triac d'un circuit de

sortie, la sortie peut rester activée ou désactivée. Pour les signaux de sortie susceptibles
d'entraîner des accidents graves, des circuits et mécanismes externes devraient être conçus pour
assurer le fonctionnement sûr des machines dans un tel cas.

AVERTISSEMENT

● Construire un circuit de verrouillage dans le programme afin que l'ensemble du système fonctionne
toujours sur le côté sûr avant d'exécuter le contrôle (pour le changement de données) du contrôleur
programmable en fonctionnement. Lisez attentivement le manuel et assurez-vous une sécurité
complète avant d'exécuter d'autres commandes (pour le changement de programme, le changement
de paramètre, la sortie forcée et le changement d'état d’opération) du contrôleur programmable en
cours de fonctionnement. Faute de quoi, la machine peut être endommagée et des accidents peuvent
se produire en raison d'opérations erronées.

● Dans un circuit de sortie, si le courant de charge excède la valeur nominale ou si une surintensité
causée par un court-circuit à la charge persiste longtemps, il peut en résulter un dégagement de
fumée avec départ de feu. Pour éviter cela, il faut configurer un circuit de sécurité externe tel qu’un
fusible.

● Quant à l'état d’opération de chacune des stations en cas de problème de communication, voir les
manuels correspondants pour le réseau. Une sortie erronée ou un dysfonctionnement peut être à
l'origine d'un accident.

● Prendre les mesures appropriées pour maintenir la sécurité sur le système du contrôleur
programmable en cas d'accès non autorisé d'un dispositif externe via le réseau. Pour maintenir la
sécurité en cas d'accès via Internet, prendre des mesures adéquates telles que l’installation d’un
pare-feu.

■Interpretation of terminal block layout

• Indication of power supply terminals

The AC power supply type has [L] and [N] terminals, whereas the DC power type has [+] and [-] terminals.
For external wiring, refer to Page 114 Power Supply Wiring.

• Indication of 24 V DC service power supply

The AC power supply type has [0V] and [24V] terminals.
Between [0V]-[0V] terminals and between [24V]-[24V] terminals of FX5U-64M, FX5U-80M(AC power supply type), the terminals
are connected internally, and short-circuit is not required.
The DC power supply type does not have a 24 V DC service power supply. [⋅] indicates open terminals.
Do not wire [⋅] terminals.

• Indication of input terminal

Both AC and DC power supply type have the same input terminals, however, the external input wiring differs from each other.
For external wiring, refer to Page 122 Input Wiring.

• Indication of output terminals connected to common (COM)

One common terminal covers 4 or 8 output points.
The output number (Y) connected to common is the range inside the thick "separation line."
For transistor output (source) type, the "COM" terminal is the "+V" terminal.

The maximum number of remote I/O points differs according to type of the network.

• When CC-Link IE field network Basic is used, remote I/O points that are used in CC-Link IE field network Basic are
occupied, and then remote I/O points of the intelligent function module are occupied. For CC-Link IE field network Basic,
refer to CC-Link IE field network Basic Reference Manual.

• When using CC-Link master (FX3U-16CCL-M) and AnyWireASLINK master (FX3U-128ASL-M) together, connect FX3U­128ASL-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.
