SAFETY PRECAUTIONS

(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.

The precautions given in this manual are concerned with this product only. For the safety precautions of

the programmable controller system, refer to the user's manual for the CPU module used.

In this manual, the safety instructions 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.

A - 2

[Design Precautions]

WARNING

Failure to observe this could lead to accidents for incorrect outputs or malfunctioning.

Configure safety circuits external to the programmable controller to ensure that the entire

system operates safely even when a fault occurs in the external power supply or the

programmable controller.

Failure to do so may result in an accident due to an incorrect output or malfunction.

(1) Configure an emergency stop circuit and interlock circuit such as a positioning upper

limit/lower limit to prevent mechanical damage outside the programmable controller.

(2) The machine zero point return operation is controlled by the zero point return direction

and zero point return speed data. Deceleration starts when the near-point dog turns ON.

Thus, if the zero point return direction is incorrectly set, deceleration will not start and the

machine will continue to travel. Configure an interlock circuit to prevent mechanical

damage outside the programmable controller.

(3) When the positioning module detects an error, the motion slows down and stops or the

motion suddenly stops, depending on the stop group setting in parameter.

Set the parameters to meet the specifications of the positioning control system used.

In addition, set the OPR parameters and positioning data within the specified setting range.

When a data link results in a communication error, the operating status of the station in

communication error changes depending on the type of the used data link. Using the

communication status information, configure an interlock circuit in the sequence program to

ensure that the system will operate safely.

For the method of checking the station in communication error and its operating status at

communication error, refer to the corresponding data link manual.

[Design Precautions]

CAUTION

Do not install the control lines or communication cables together with the main circuit lines or

power cables.

Keep a distance of 100mm or more between them.

Failure to do so may result in malfunction due to noise.

A - 3

[Installation Precautions]

CAUTION

Use the programmable controller in an environment that meets the general specifications in

this manual.

Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of

the product.

Securely fix the module using the DIN rail or mounting screws and fully tighten the mounting

screws within the specified torque range. If the screws are loose, it may result in fallout, short

circuits, or malfunctions. Tightening the screw too far may cause damages to the screws and/or

the module, resulting in a fallout, short circuits, or malfunctions.

Securely connect the external device connection connector and peripheral device connection

connector into the module connector until a click is heard.

Improper connection could lead to a connection fault, and to incorrect inputs and outputs.

When not connecting the drive unit and peripheral device, always install a cover on the

connector section.

Failure to observe this could lead to malfunctioning.

[Wiring Precautions]

WARNING

Check the rated voltage and terminal layout before wiring to the programmable controller, and

connect the cables correctly. Connecting a power supply with a different voltage rating or

incorrect wiring may cause a fire or failure.

Check the terminal layout before wiring to the module, and connect the cables correctly.

Prevent foreign matter such as dust or wire chips from entering the module.

Such foreign matter can cause a fire, failure, or malfunction.

[Wiring Precautions]

!CAUTION

Tighten the terminal screws within the range of the specified torque.

If the terminal screws are loose, it may result in short circuits, or malfunctions. Tightening the

terminal screws too far may cause damages to the terminal screws and/or the module, resulting

in short circuits, or malfunctions.

Be sure there are no foreign substances such as sawdust or wiring debris inside the module.

Such debris could cause fires, failure, or malfunction.

Individually ground the FG terminal of the programmable controller with a ground resistance of

100 ohms or less. Failure to do so may result in malfunction.

Place the cables in a duct or clamp them.

If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module

or cables or malfunction due to poor contact.

Keep a certain distance between the control wires and the communication cables.

Noise can cause a malfunction.

When disconnecting a cable from the module, do not pull on the cable itself. Disconnect cables

not fitted with a 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 can cause damage to the module or cable, or ,malfunction due to cable

connection faults.

A - 4

[Startup and Maintenance Precautions]

!CAUTION

Do not touch any terminal while power is on.

Doing so will cause electric shock or malfunction.

Never disassemble or modify the module.

Failure to observe this could lead to trouble, malfunctioning, injuries or fires.

Switch off all phases of the externally supplied power used in the system before cleaning or

tightening the screws.

Failure to turn all phases OFF could lead to electric shocks.

Make sure to install or remove the module from the panel after switching off all phases of the

externally supplied power for the system.

Failure to turn all phases OFF could lead to module trouble or malfunctioning.

Before starting test operation, set the parameter speed limit value to the slowest value, and

make sure that operation can be stopped immediately if a hazardous state occurs.

Do not install/remove the terminal block more than 50 times after the first use of the product.

(IEC 61131-2 compliant)

Always make sure to touch the grounded metal to discharge the electricity charged in the body,

etc., before touching the module.

Failure to do so may cause a failure or malfunctions of the module.

[Precautions for use]

!CAUTION

Note that when the reference axis speed is designated for interpolation operation, the speed of

the partner axis (2nd axis) may be larger than the set speed (larger than the speed limit value).

[Disposal Precautions]

!CAUTION

When disposing of the product, handle it as industrial waste.
