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.

[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.

[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.
