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".
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.
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
Provide a safety circuit outside the programmable controller so that the entire system will
operate safely even when an external power supply error or programmable controller fault
occurs.
Failure to observe this could lead to accidents for incorrect outputs or malfunctioning.
(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 OPR operation is controlled by the OPR direction and OPR speed data.
Deceleration starts when the near-point dog turns ON. Thus, if the OPR 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 module detects an error, normally deceleration stop or sudden stop will take
place according to the parameter stop group settings.
Set the parameters to the positioning system specifications.
Make sure that the OPR parameter and positioning data are within the parameter setting
values.
WARNING
CAUTION

A - 2
[Design Precautions]
!CAUTION
Do not bundle or adjacently lay the connection cable connected to the module external I/O
signals or drive unit with the main circuit line, power line, or the load line other than that for the
programmable controller. Separate these by 100mm as a guide. Failure to observe this could
lead to malfunctioning caused by noise, surge, or induction.
[Mounting Precautions]
!CAUTION
Use the programmable controller in an environment that meets the general specifications
contained in QCPU User's Manual(Hardware Design, Maintenance and Inspection) to use.
Using this programmable controller in an environment outside the range of the general
specifications may cause electric shock, fire, malfunction, and damage to or deterioration of the
product.
While pressing the installation lever located at the bottom of module, insert the module fixing
tab into the fixing hole in the base unit until it stops. Then, securely mount the module with the
fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much vibration, tighten the
module with a screw.
Tighten the screw in the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or
module.
Completely turn off the externally supplied power used in the system before mounting or
removing the module.
Not doing so may damage the product.
[Wiring Precautions]
!WARNING
Always confirm the terminal layout before connecting the wires to the module.

A - 3
[Wiring Precautions]
!CAUTION
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.
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/Maintenance Precautions]
!WARNING
Completely turn off 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.

A - 4
[Startup/Maintenance Precautions]
!CAUTION
Never disassemble or modify the module.
Failure to observe this could lead to trouble, malfunctioning, injuries or fires.
Completely turn off the externally supplied power used in the system before installing or
removing the module.
Failure to turn all phases OFF could lead to module trouble or malfunctioning.
Do not install/remove the module to/from the base unit, or the terminal block to/from the module
more than 50 times after the first use of the product. (IEC 61131-2 compliant)
Failure to do so may cause malfunction.
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.
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, 3rd axis and 4th 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.
