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 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

●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) When using a servo amplifier with Servo ON signal, connect the signal to the module. When using

a servo amplifier whose control cannot be stopped through Servo ON signal, satisfy the following.

• Analog voltage must be 0V (motor stop) to power off the programmable controller.

(2) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured

external to the programmable controller.

(3) OPR (Original Point Return) is controlled by two kinds of data: OPR direction and OPR speed.

Deceleration starts when the near-point dog turns on. If an incorrect OPR direction is set, motion

control may continue without deceleration. To prevent machine damage caused by this, configure

an interlock circuit external to the programmable controller.

●Do not write any data to the "system area" of the buffer memory in the intelligent function module.

Also, do not use any "use prohibited" signal as an output signal from the CPU module to the intelligent

function module. Doing so may cause malfunction of the programmable controller system.

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate injury or property damage.

[Installation Precautions]

CAUTION

●Do not install the connection cables for external I/O signals and for the drive unit together with the

main circuit lines, power cables, or load circuit lines of a device other than the programmable

controller.

Keep a distance of 100mm or more between them.

Failure to do so may result in malfunction due to noise, surges, and induction.

CAUTION

●Use the programmable controller in an environment that meets the general specifications in the user’s

manual for the CPU module used.

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

product.

●To mount the module, while pressing the module mounting lever located in the lower part of the

module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the

module until it snaps into place.

Incorrect mounting may cause malfunction, failure or drop of the module.

When using the programmable controller in an environment of frequent vibrations, fix the module with

a screw.

●Tighten the screws within the specified torque range.

Undertightening can cause drop of the screw, short circuit or malfunction.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

●Securely connect the drive unit connector and external device connector to the connector on the

module. Poor contact may cause incorrect input or output.

●Do not directly touch any conductive parts and electronic components of the module.

Doing so can cause malfunction or failure of the module.

●Shut off the external power supply (all phases) used in the system before mounting or removing the

module. Failure to do so may result in damage to the product.

[Wiring Precautions]

WARNING

●Shut off the external power supply (all phases) used in the system before installation and wiring.

Failure to do so may result in electric shock or cause the module to fail or malfunction.

●After installation and wiring, attach the included terminal cover to the module before turning it on for

operation. Failure to do so may result in electric shock.

CAUTION

●Check the rated voltage and terminal layout before wiring to the module, and connect the cables

correctly.

Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire or

failure.

●Use applicable solderless terminals and tighten them within the specified torque range.

If any spade solderless terminal is used, it may be disconnected when the terminal screw comes

loose, resulting in failure.

●Tighten the connector screws within the specified torque range.

Undertightening can cause short circuit, fire, or malfunction.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, fire, or

malfunction.

●Connectors for external devices must be crimped with the tool specified by the manufacturer or must

be correctly soldered.

Incomplete connections may cause short circuit, fire, or 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.

●When disconnecting the cable from the module, do not pull the cable by the cable part. For the cable

with connector, hold the connector part of the cable.

Pulling the cable connected to the module may result in malfunction or damage to the module or

cable.

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

cause a fire, failure, or malfunction.

●A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,

from entering the module during wiring. Do not remove the film during wiring. Remove it for heat

dissipation before system operation.

[Startup and Maintenance Precautions]

[Precaution during operation]

[Disposal Precaution]

WARNING

●Shut off the external power supply (all phases) used in the system before cleaning the module or

retightening the connector screws. Failure to do so may result in electric shock.

CAUTION

●Do not disassemble or modify the module.

Doing so may cause failure, malfunction, injury, or a fire.

●Shut off the external power supply (all phases) used in the system before mounting or removing a

module. Failure to do so may cause the module to fail or malfunction.

●After the first use of the product, do not mount/remove the module to/from the base unit, and the

terminal block to/from the module more than 50 times (IEC 61131-2 compliant) respectively.

Exceeding the limit may cause malfunction.

●Before testing operation, set a low speed value for the speed limit parameter so that the operation can

be stopped immediately upon occurrence of a hazardous condition.

●Before handling the module, touch a conducting object such as a grounded metal to discharge the

static electricity from the human body. Failure to do so may cause the module to fail or malfunction.

CAUTION

●When changing data and operating status, and modifying program of the running programmable

controller from an external device such as a personal computer connected to an intelligent function

module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or

modification may cause system malfunction, damage to the machines, or accidents.

CAUTION

●When disposing of this product, treat it as industrial waste.
