injury.

Indicates that incorrect handling may cause
hazardous conditions, resulting in minor or moderate
injury or property damage.

CAUTION

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals
carefully and pay full attention to safety to handle the product correctly.

In this manual, the safety precautions are classified into two levels:
" WARNING" and " CAUTION".

Under some circumstances, failure to observe the precautions given under
" CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal
and system safety.
Make sure that the end users read this manual and then keep the manual in a safe
place for future reference.

[Design Precautions]

WARNING

● If data link becomes faulty, the status of the faulty station changes as follows.
Using the communication status information, construct an interlock circuit in
the sequence program so that the system operates safety.
There is a risk of an accident due to output error or malfunction.
(1) All general-use inputs from this module turn off.
(2) All general-use outputs from this module turn off.

● The inputs and outputs may be turned on or off when a failure occurs within
the module. Provide a circuit that externally monitors the input and output
signals that might lead to a serious accident.

A-1

[Design Precautions]

CAUTION

● Do not have control cables and communication cables bundled with or placed
near by the main circuit and/or power cables.
Wire those cables at least 100mm (3.94 inch) away from the main circuit
and/or power cables.
Not doing so could result in noise that would cause erroneous operation.

[Installation Precautions]

CAUTION

● Use each module in an environment as specified in the "general specification"
in the detailed manual.
Usage of the module outside the general specification range may cause
electric shock, fire, malfunction, product damage or deterioration.

● Tighten the module securely using DIN rail or installation screws within the
specified torque range of the installation screws. Loose screws may cause
falling or malfunction. Also, if the screws are too tight, it may cause falling or
malfunction due to damage of the screws or module.

● Do not touch the conductive area of the module.
Doing so may cause module malfunction or breakdowns.

[Wiring Precautions]

WARNING

● Perform installation and wiring after disconnecting the power supply at all
phases externally.
If the power is not disconnected at all phases an electric shock, product
damage or malfunction may result.

● When powering up or operating the module after performing installation or
wiring work, always attach the terminal cover that came with the product.
It may cause an electric shock if the terminal cover is not attached.

A-2

[Wiring Precautions]

CAUTION

● Be sure to ground the FG terminal to the class-3 or higher grounding.
Otherwise there will be a danger of malfunctions.

● Use applicable solderless terminals and tighten them with the specified
torque. If any solderless spade terminal is used, it may be disconnected when
the terminal screw comes loose, resulting in failure.

● Perform correct wiring for the module according to the product's rated voltage
and terminal arrangement. Connecting to a power supply different from rating
or mis-wiring may cause fire and/or product failure.

● Fix terminal screws securely within the specified torque range. Loose terminal
screws may cause short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short
circuit, or malfunction.

● Make sure foreign objects do not get inside the module, such as dirt and wire
chips. It may cause fire, product failure or malfunction.

● Be sure to fix the wires or cables that are connected to the module in place,
either by running them through a duct or by using clamps.
If the cables are not fixed in one of these ways, dispersion, movement, or
careless pulling of the cables may cause damage to the module or
malfunction due to cable contact faults.

● Do not install the control lines together with the communication cables, or
bring them close to each other. Failure to do so may cause malfunctions due
to noise.

● When disconnecting a communication or power supply cable from the
module, do not pull on the cable itself.
Disconnect cables fitted with connectors by holding and pulling the cable
connector. Disconnect cables not fitted with a connector by removing the
screws from the part connected to the module.
Pulling on a cable that is connected to the module can cause damage to the
module or cable, or malfunction due to cable connection faults.

[Starting and Maintenance Precautions]

WARNING

● Do not touch the terminals when the power is on. It may cause an electric
shock or malfunction.

● Perform cleaning the module after turning off the all external power supply for
sure. If you do not switch off the external power supply, it will cause electric
shock.

A-3

[Starting and Maintenance Precautions]

CAUTION

● Never try to disassemble or modify module. It may cause product failure,
malfunction, fire or cause injury.

● Do not drop or apply strong shock to the module case. Failure to do so may
damage the module.

● Make sure to switch all phases of the external power supply off before
installing or removing the module to/from the panel.
If you do not switch off the external power supply, it will cause failure or
malfunction of the module.

● Always set the setting pins for pulse and external input voltage after externally
shutting down all phases of the power supply.
Failure to shut down all phases of the power supply may cause a failure or
malfunction of the module.

● Do not install/remove the terminal block more than 50 times after the first use
of the product. (IEC 61131-2 compliant)

5.1 Wiring Method to Each Module

The following diagram shows the wiring of the master module, remote
module and high-speed counter module with dedicated cable for CC­Link.

Point

Always connect the "terminal resistors" provided with the master module
to the modules at both ends of data link.
(Connect between DA and DB)

5.2 Precautions When Wiring to the Pulse Generator

(1) Implement the following types of noise measures for high-speed

pulse input.

(a) Always use a twisted shielded wire and perform class 3

grounding.

(b) Do not run the twisted wire parallel to the power cord or I/O line

with a lot of noise. Secure a distance of 150mm (5.91in.) or
more and run the cable for the shortest distance possible.

(2) In the case of Phase 1 input, always wire to the Phase A side.

(3) The high-speed counter module counts up when a pulse-state

noise is input, resulting in a count error.

(4) Wiring for noise measure is indicated below.

High­speed
counter
module

Inverter

Terminal
block

block

*1

For a strong power device
such as an inverter, leave a
distance of 150mm (5.91in.)
or more from the I/O line
(Also be careful of the
wiring inside the panel.)

EWV

Joint box

*2

AC motor

Carrier

Encoder

*1 When using metal piping, avoid intermingling solenoid valves and inductive loads in the

same piping. Also, if an isolation distance from a strong power line such as duct wiring
cannot be secured, use a CVVS or other shielded cable for the strong power line.

20

*2 Make the distance from the encoder to the joint box short. When there is long distance from

the high-speed counter module to the encoder, voltage drops will occur. Therefore, use a
measuring device such as a tester on the joint box terminal block to check whether the
voltage while the encoder is operating and at a standstill is within the rated voltage for the
encoder. If the drop in voltage is large, make the cable size thicker or use a 24V DC type
encoder with small current consumption.

• Grounding for the twisted, shielded cable is done on the encoder side (in the joint
box). (The following is an example of a connection for a 24V sink load.)

+24V

Current for the encoder

To the high-speed

The shielded cable for the encoder and that for the twisted cable
are connected inside the joint box. If the shielded cable for the
encoder is not grounded inside the encoder, then perform
grounding inside the joint box as shown by the dotted line.

• Set the pulse/external input voltage setting pin correctly after confirming the
rated voltage for the external power supply.
If there is a fault in the wiring (setting mistake), fire or breakdown can be
caused.

• Always set the pulse/external input voltage setting pin after shutting down all
phases of the power supply externally.
If all phases are not shut down, this will cause a breakdown of the module or
an error in operation.

• Make sure the insertion direction of the jumper for the pulse/ external-input
voltage setting pin is correct.
Incorrect insertion direction may cause the module to breakdown.
