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].
Depending on the circumstances, procedures indicated by [CAUTION] may also cause severe injury.
It is important to follow all precautions for personal safety.
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 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 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.
1
[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).

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.

The total number of input/output points must not exceed 256 points.
Total number of input/output points of the CPU module and I/O modules
Count the total number of input/output points of the CPU module and I/O modules.
To obtain the total number of input/output points, count the input points (X000 and more) and output points (Y000 and more) of
the CPU module and I/O modules.
For details on the number of input/output points by model, refer to the following.
Page 32 CPU Module

Number of occupied input/output points of intelligent function modules
Count the number of occupied input/output points of intelligent function modules.
The number of occupied input/output points per module is 8.
For details on the number of occupied input/output points by model, refer to Page 34 Intelligent Function Module.
Calculation of number of remote I/O points
If the master module of the network is used, calculate the number of remote I/O points connected on the network.
The total number of remote I/O points must not exceed 384 points.
The maximum number of remote I/O points differs according to type of the network.
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.
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.

In some cases, depending on extension devices used, it may not be possible to receive the input signal, due to the insufficient
current. Take the following action in such case.
In the case of capturing high-speed pulses
When capturing pulses of a response frequency of 50 to 200 kHz on using the input X000 to X007 (FX5U-32M is X000 to
X005.), wire the terminals as stated below.
• The wiring length should be 5 m (16'4") or less.
• Use shielded twisted-pair cables for connecting cables. Ground the shield of each shielded cable only on the CPU module
side.
• Connect a 1.5 k (1 W or more) bleeder resistance to the input terminal, so that the sum of the load current of the open
collector transistor output on the mating device and the input current of the CPU module is 20 mA or more.
The above-mentioned restrictions are due to specifications of connecting device (encoder etc.).
Please adjust the cable length and load, for connecting device.

6.6Output 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.
• Test condition: 1 sec. ON/1 sec. OFF

0.17 A/200 V AC
80 VA0.8 A/100 V AC200,000 times
0.4 A/200 V AC
6
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.

■Output terminal
One common terminal is used for 4 or 8 relay output points.
The common terminal blocks can drive loads of different circuit voltage systems (for example,100 V AC and 24 V DC).
■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.

Wiring to the built-in analog I/O terminals of the CPU module is explained below.
For specifications of the built-in analog I/O terminals of the CPU module, refer to Page 25 Built-in Analog Specifications.
Analog input wiring
*1 For analog input wiring, use shielded twisted-pair cables (double-core type). Separate them from other power lines or lines which can be
induced by others.
*2 For unused channels, short-circuit the "V+" and "V-" terminals.
Analog output wiring
*1 For analog output wiring, use shielded twisted-pair cables (double-core type). Separate them from other power lines or lines which can
be induced by others.
*2 Ground a shielded cable at one point on the signal receiving side.
