4-3 Mounting Units
The Units that make up an NJ-series Controller can be connected simply by pressing the Units together
and locking the sliders by moving them toward the back of the Units. The End Cover is connected in the
same way to the Unit on the far right side of the Controller.
1Join the Units so that the connectors fit exactly.
2The yellow sliders at the top and bottom of each Unit lock the Units together. Move the sliders
toward the back of the Units as shown below until they click into place.

WARNING
WARNING
Wiring
Connect this Controller correctly to the servo amplifier, encoder, limit sensors, Galvo
Scanner, and laser according to the instructions in this manual. Not doing so may
cause the motor to run away, etc., resulting in serious accidents.
For the Power Supply Unit or any other power supply connected to peripheral devices,
connect the 0-V side to ground, or do not ground them at all.
Depending on how devices connected to the non-insulated circuit are grounded, the
power supply may be short-circuited.
Never ground the 24-V side of the power supply, as shown in the following figure.

During Power Supply
Do not attempt to take any Unit apart.
In particular, high-voltage parts are present in the Power Supply Unit while power is
supplied or immediately after power is turned OFF. Touching any of these parts may
result in electric shock. There are sharp parts inside the Unit that may cause injury.
Fail-safe Measures
Provide safety measures in external circuits to ensure safety in the system if an abnor-
mality occurs due to malfunction of the system or due to other external factors affecting
operation. Not doing so may result in serious accidents due to incorrect operation.
Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures
must be provided in external control circuits.
You must take fail-safe measures to ensure safety in the event of incorrect, missing, or
abnormal signals caused by broken signal lines, momentary power interruptions, or
other causes.
Safety Precautions

CK3M/CK5M Series Programmable Multi-Axis Controller Hardware User's Manual (O036)

The UPS used enables normal operation to continue for a certain period of time if a
momentary power interruption occurs. This means that the CK3M-series Controller
may receive incorrect signals from external devices that are also affected by the power
interruption. Accordingly, take suitable actions, such as establishing external fail-safe
measures and interlock conditions, to monitor the power supply voltage of the external
device as required.
Unintended outputs may occur if an error occurs in internal data of the Controller. As a
countermeasure for these problems, external safety measures must be provided to en-
sure safe operation of the system.
The Controller will turn OFF all outputs of output units in the following cases and the
slaves will operate according to the settings in the slaves.
• If a power supply error occurs
•If the connected power supply is faulty
• If a CPU Unit error (watchdog timer error) or CPU Unit reset occurs
• If a major fault level Controller error occurs
• While the Controller is on standby until RUN mode is entered after the power is
turned ON
• If a system initialization error occurs
External safety measures must be provided to ensure safe operation of the system in
such cases.
The outputs may remain ON or OFF due to welding or burning of the output relays or
destruction of the output transistors. As a countermeasure for these problems, external
safety measures must be provided to ensure safe operation of the system.
To ensure safe use of the Controller, correctly make the limit settings for the position,
speed, acceleration, jerk, current, and following error, as well as the encoder loss de-
tection.
For devices that move in a vertical direction, use a motor brake to prevent them from
falling down when the servo control is stopped.
Downloading
Always confirm safety at the destination before you transfer a user program, configura-
tion data, or setup data from the Power PMAC IDE.
The devices or machines may perform unexpected operation regardless of the operat-
ing mode of the Controller.
After you transfer the user program, the Controller is restarted and communications
with the EtherCAT slaves are cut off. During that period, the slave outputs behave ac-
cording to the slave specifications.
The time that communications are cut off depends on the EtherCAT network configura-
tion.
Before you transfer the user program, confirm that the system will not be adversely af-
fected.

Test Run
Before you start a Test Run, make sure that the operation parameters are set correctly.
Actual Operation
Check the user program, servo algorithm, data, and parameter settings for proper exe-
cution before you use them for actual operation.
Security Measures
Anti-virus protection
Install the latest commercial-quality antivirus software on the computer connected to
the control system and maintain to keep the software up-to-date.
Security measures to prevent unauthorized access
Take the following measures to prevent unauthorized access to our products.
•Install physical controls so that only authorized personnel can access control sys-
tems and equipment.
• Reduce connections to control systems and equipment via networks to prevent ac-
cess from untrusted devices.
• Install firewalls to shut down unused communications ports and limit communica-
tions hosts and isolate control systems and equipment from the IT network.
• Use a virtual private network (VPN) for remote access to control systems and equip-
ment.
• Adopt multifactor authentication to devices with remote access to control systems
and equipment.
• Set strong passwords and change them frequently.
• Scan virus to ensure safety of USB drives or other external storages before connect-
ing them to control systems and equipment.
Data input and output protection
Validate backups and ranges to cope with unintentional modification of input/output da-
ta to control systems and equipment.
• Checking the scope of data
• Checking validity of backups and preparing data for restore in case of falsification
and abnormalities
• Safety design, such as emergency shutdown and fail-soft operation in case of data
tampering and abnormalities
Data recovery
Backup data and keep the data up-to-date periodically to prepare for data loss.
When using an intranet environment through a global address, connecting to a SCADA
or an unauthorized terminal such as an HMI or to an unauthorized server may result in
network security issues such as spoofing and tampering. You must take sufficient
measures such as restricting access to the terminal, using a terminal equipped with a
secure function, and locking the installation area by yourself.
Safety Precautions

CK3M/CK5M Series Programmable Multi-Axis Controller Hardware User's Manual (O036)

When constructing an intranet, communication failure may occur due to cable discon-
nection or the influence of unauthorized network equipment. Take adequate measures,
such as restricting physical access to network devices, by means such as locking the
installation area.
When using a device equipped with the SD Memory Card function, there is a security
risk that a third party may acquire, alter, or replace the files and data in the removable
media by removing the removable media or unmounting the removable media. Please
take sufficient measures, such as restricting physical access to the Controller or taking
appropriate management measures for removable media, by means of locking the in-
stallation area, entrance management, etc., by yourself.
