WARNING

Safety Precautions

WARNING

During Power Supply

Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock.

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 result in electric shock. There are sharp parts inside the Unit that may cause injury.

. Touching any of these parts may

Fail-safe Measures

Provide safety measures in external circuits to ensure safety in the system if an abnormality occurs due to malfunction of the CPU Unit, slaves, or Units 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.

The Controller outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safe operation of the system.

The CPU Unit will turn OFF digital outputs on the CPU Rack in the following cases.

• While the CPU Unit is on standby until RUN mode is entered after the power is turned ON If an error occurs in the power supply

•

• If a system initialization error occurs

Digital outputs on the CPU Rack will produce outputs according to the settings in the following cases.

• If a CPU Unit error or CPU Unit reset occurs

• If a major fault level Controller error occurs

External safety measures must be provided to ensure safe operation of the system in such cases.

If there is interference in remote I/O communications or if a major fault level error occurs, output status will depend on the products that are used. Confirm the operation that will occur when there is interference in communications or a major fault level error, and implement safety measures. Correctly set all of the settings in the slaves and Units.

If external power supplies for Units, slaves or other devices are overloaded or shortcircuited, the voltage will drop, outputs will turn OFF, and the system may be unable to read inputs. Provide external safety measures in controls with monitoring of external power supply voltage as required so that the system operates safely in such a case.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Safety Precautions

Unintended outputs may occur when an error occurs in variable memory. As a countermeasure for such problems, external safety measures must be provided to ensure safe operation of the system.

Provide measures in the communications system and user program to ensure safety in the overall system even if errors or malfunctions occur in data link communications or remote I/O communications.

The NX-series Controller continues normal operation for a certain period of time when a momentary power interruption occurs. This means that the NX-series Controller may receive incorrect signals from external devices that are also affected by the power interruption. Accordingly, take suitable actions, such as external fail-safe measures and interlock conditions, to monitor the power supply voltage of the external device as required.

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. Not doing so may result in serious accidents due to incorrect operation.

Voltage and Current Inputs

Make sure that the voltages and currents that are input to the slaves and Units are within the specified ranges. Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.

Downloading

Always confirm safety at the destination before you transfer a user program, configuration data, setup data, or device variables from the Sysmac Studio. The devices or machines may perform unexpected operation regardless of the operating mode of the CPU Unit.

Actual Operation

Check the user program, data, and parameter settings for proper execution before you use them for actual operation.

Safety Precautions

Cautions

Application

Do not touch any Unit when power is being supplied or immediately after the power supply is turned OFF. Doing so may result in burn injury

Wiring

Be sure that all terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals. The loose screws may result in fire or malfunction.

When you connect a computer or other peripheral device to a Controller that has a non-isolated DC power supply, either ground the 0-V side of the external power supply for the Unit power supply or do not ground it at all. If the peripheral devices are grounded incorrectly, the external power supply for the Unit power supply may be short-circuited. Never ground the 24-V side of the power supply, as shown in the following figure.

Online Editing

Execute online editing only after confirming that no adverse effects will be caused by deviations in the timing of I/O.

Safety Precautions

If the cable redundancy function is enabled, always write a program to confirm that the network is in the cable redundancy status. If the program is not written, you cannot check that the network is not in the cable redundancy status due to a disconnection on the ring topology. Use the _EC_RingBreaking system-defined variable to confirm that the network is in the cable redundancy status.

Version Information

The cable redundancy function can be used with project unit version 1.40 or later.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

Transporting and Disassembly

• Do not attempt to disassemble, repair, or modify any Units. Doing so may result in malfunction or

fire.

• Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit mal-

function or burning.

• When transporting any Unit, use the special packing box for it. Also, do not subject the Unit to ex-

cessive vibration or shock during transportation.

Mounting

• Always turn OFF the power supply before mounting the Units. If the power supply is not OFF, the

Unit may result in malfunction or may be damaged.

• Do not apply labels or tape to the Unit. When the Unit is installed or removed, adhesive or scraps

may adhere to the pins in the NX bus connector, which may result in malfunctions.

• Do not touch the pins in the NX bus connector on the Unit. Dirt may adhere to the pins in the NX bus

connector, which may result in malfunctions.

• Do not write on the CPU Unit with ink within the restricted region that is shown in the following fig-

ure. Also do not get this area dirty. When the Unit is installed or removed, ink or dirt may adhere to

the pins in the NX bus connector

Refer to the user’s manual for the connected NX Unit for information on the restricted region for the

NX Unit.

Precautions for Safe Use

• The End Cover has a metal portion and is heavier than it looks. Be careful not to drop it when han-

dling.

Installation

• Always connect to a ground of 100 Ω or less when installing the Units.

Wiring

• Follow the instructions in this manual to correctly perform wiring.

Double-check all wiring and switch settings before turning ON the power supply.

Use the methods that are specified in this manual for wiring the terminal blocks.

•

• Use crimp terminals for wiring the M3 screw terminal blocks. Do not connect bare stranded wires

directly to the M3 screw terminal blocks.

• Use the correct wiring parts and tools when you wire the system. Otherwise, cables may be discon-

nected to cause short-circuit or wire breakage.

• Do not pull on the cables or bend the cables beyond their natural limit.

Do not place heavy objects on top of the cables or other wiring lines. Doing so may break the ca-

bles.

• Mount terminal blocks, connectors, and Option Boards only after checking the mounting location

carefully.

• Be sure that the terminal blocks, communications cables, and Option Boards with tightening screws

or locking devices are properly tightened to or locked into place.

• If the external power supply to a built-in output, Output Unit or slave has polarity, connect it with the

correct polarity. If the polarity is reversed, current may flow in the reverse direction and damage the

connected devices regardless of the operation of the Controller.

• When you insert a flat-blade screwdriver into a release hole on a screwless clamping terminal block

of CPU Unit, press it down with a force of 30N or less. Applying excessive force may damage the

terminal block.

• Do not incline or twist the flat-blade screwdriver while it is in a release hole on a screwless clamping

terminal block of CPU Unit. Doing so may damage the terminal block.

the specific NX Unit for how to wire an NX Unit.

Power Supply Design

• Select an external power supply with sufficient capacity by considering the power supply capacity or

inrush current when the power is turned ON that is specified in this manual.

Otherwise, the external power supply may not be turned ON or malfunction due to unstable power

supply voltage.

•

Use the I/O power supply current for the CPU Rack of NX1P2 CPU Unit at 4 A or less. Using the

currents that are outside of the specifications may cause failure or damage.

Use all Units within the I/O power supply ranges that are given in the specifications.

•

• Do not apply voltages that exceed the rated value to any Input Unit, slave, or input built in the CPU

Unit.

• Do not apply voltages or connect loads to the Output Units, slaves, or CPU Unit’s internal outputs in

excess of the ratings.

• Surge current occurs when the power supply is turned ON. When selecting fuses or breakers for

external circuits, consider the above precaution and allow sufficient margin in shut-off performance.

Refer to this manual for surge current specifications.

• If the full dielectric strength voltage is applied or turned OFF using the switch on the tester, the gen-

erated impulse voltage may damage the Power Supply Unit. Use the adjustment on the tester to

gradually increase and decrease the voltage.

• Install external breakers and take other safety measures against short-circuiting and overcurrents in

external wiring.

• Do not apply voltages or connect loads in excess of the maximum switching capacity.

Turning ON the Power Supply

• It takes approximately 20 seconds to enter RUN mode after the power supply is turned ON. During

that time, digital outputs on the CPU Rack will be OFF. The slave outputs behave according to the

setting values.

Use the system-defined variables and the NX Unit device variables in the user program to confirm

that I/O data communications are established before attempting control operations. External com-

munications are also not performed during startup.

•

Configure the external circuits so that the power supply to the control system turns ON only after the

power supply to the Controller has turned ON. If the power supply to the Controller is turned ON

after the control power supply, temporary errors may result in incorrect control system signals

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

because the output terminals on Output Units may momentarily turn ON when power supply is

turned ON to the Controller.

•

If you transfer data from a backup file on an SD Memory Card to the Controller when the power sup-

ply is turned ON, properly select the data groups to transfer. If the data for an unintended data group

is transferred to the Controller, it may cause the equipment to operate unpredictably.

• You cannot obtain normal input data from NX Units while the Units are restarting. Use the system-

defined variables or device variables for the NX Units on the CPU Unit in the user program to check

the validity of the I/O data before you attempt control operations.

Actual Operation

• If you change the fail-soft operation setting, the output status when the error occurs may also

change. Confirm safety before you change the setting.

• If you use fail-soft operation, write programming to determine whether Unit I/O data is valid. Without

such programming, the user program cannot distinguish between Units for which I/O refreshing is

continued and Units for which I/O refreshing is stopped.

Turning OFF the Power Supply

• Never turn OFF the power supply to the Controller when the BUSY indicator is flashing. While the

BUSY indicator is lit, the user program and settings in the CPU Unit are being backed up in the built-

in non-volatile memory. This data will not be backed up correctly if the power supply is turned OFF.

Also, a major fault level Controller error will occur the next time you start operation, and operation

will stop.

•

Do not turn OFF the power supply or remove the SD Memory Card while SD Memory Card access

is in progress (i.e., while the SD BUSY indicator flashes). Data may become corrupted, and the

Controller will not operate correctly if it uses corrupted data. To remove the SD Memory Card from

the CPU Unit while the power supply is ON, press the SD Memory Card power supply switch and

wait for the SD BUSY indicator and SD PWR indicator to turn OFF before you remove the SD Mem-

ory Card.

• Do not disconnect the cable or turn OFF the power supply to the Controller when downloading data

or the user program from Support Software.

• Always turn OFF the power supply to the Controller before you attempt any of the following.

a) Mounting or removing the Units

b) Assembling the Units

c) Setting DIP switches or rotary switches

d) Connecting cables or wiring the system

e) Connecting or disconnecting the terminal blocks or connectors

f) Mounting or removing the Option Boards

The Power Supply Unit may continue to supply power to the rest of the Controller for a few seconds

after the power supply turns OFF. The POWER indicator is lit during this time. Confirm that the

POWER indicator is not lit before you perform any of the above.

Operation

• Confirm that no adverse effect will occur in the system before you attempt any of the following.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

a) Changing the operating mode of the CPU Unit (including changing the setting of the Startup

Mode)

b) Changing the user program or settings

c) Changing set values or present values

d) Forced refreshing

e) Starting the CPU Unit with the battery exhausted

f) Restarting a slave or Unit after you change any settings

g) Transferring a backup file on the SD Memory Card

• After you change any slave or Unit settings, carefully check the safety of the controlled system be-

fore you restart the Unit.

•

If two different function modules are used together, such as when you use EtherNet/IP and Ether-

CAT slaves, take suitable measures in the user program and external controls to ensure that safety

is maintained in the controlled system if one of the function modules stops. The relevant outputs will

behave according to the slave or Unit specifications if a partial fault level error occurs in one of the

function modules.

• Always confirm safety at the connected equipment before you reset Controller errors with an event

level of partial fault or higher for the EtherCAT Master Function Module.

When the error is reset, all slaves that were in any state other than Operational state due to a Con-

troller error with an event level of partial fault or higher (in which outputs are disabled) will go to Op-

erational state and the outputs will be enabled.

Before you reset all errors or restart a slave, confirm that no Controller errors with an event level of

partial fault have occurred for the EtherCAT Master Function Module.

Battery Backup

• If you use the clock data in the user program and turn OFF the power supply for a long time, use a

Battery which is sold separately.

The Battery is not mounted when the product is at factory setting. The clock data is retained by the

built-in capacitor

power is not supplied. If the power OFF time rate is high, the clock data is initialized and malfunc-

tions may occur in the program for which the clock data is used.

• If you use the Battery, connect the Sysmac Studio and set the Battery-related error detection to

Use. The Battery-related error detection is set to Do not use at the factory setting because the

Battery is not built in. If the Battery-related error detection is set to Do not use, an error cannot be

detected when the Battery is exhausted and malfunctions may occur in the program for which the

clock data is used.

. The capacitor is charged while the power is supplied and discharged while the

Debugging

• Forced refreshing ignores the results of user program execution and refreshes I/O with the specified

values. If forced refreshing is used for inputs for which I/O refreshing is not supported, the inputs will

first take the specified values, but they will then be overwritten by the user program. Be careful that

this operation differs from the force-set/reset functionality of the CJ/CP-series PLCs.

•

You cannot upload or download information for forced refreshing with the Sysmac Studio.

After downloading data that contains forced refreshing, change to RUN mode and then use the Sys-

mac Studio to perform the operation for forced refreshing.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

Depending on the difference in the forced status, the control system may operate unexpectedly.

• Do not specify the same address for the A

Doing so would allow the same entity to be accessed with different variable names, which would

make the user program more difficult to understand and possibly cause programming mistakes.

T specification for more than one variable.

General Communications

• When you use data link communications, check the error information that is given in _ErrSta (Con-

troller Error Status) to make sure that no error has occurred in the source device. Create a user pro-

gram that uses reception data only when there is no error in the source device.

If there is an error in the source device, the data for the data link may contain incorrect values.

• Unexpected operation may result if inappropriate data link tables are set. Even if appropriate data

link tables have been set, confirm that the controlled system will not be adversely affected before

you transfer the data link tables. The data links start automatically after the data link tables are

transferred.

EtherNet/IP Communications

• Make sure to use the communications distance, number of nodes connected, and method of con-

nection for EtherNet/IP within specifications. Do not connect EtherNet/IP communications to Ether-

CAT or other networks. An overload may cause the network to fail or malfunction.

•

All related EtherNet/IP nodes are reset when you transfer settings for the built-in EtherNet/IP port

(including IP addresses and tag data links settings). The settings can only be enabled after the re-

set. Confirm that the system will not be adversely affected by resetting nodes before you transfer the

settings.

• If EtherNet/IP tag data links (cyclic communications) are used with a repeating hub, the communica-

tions load on the network will increase. This will increase collisions and may prevent stable commu-

nications. Do not use repeating hubs on networks where tag data links are used. Use an Ethernet

switch instead.

EtherCAT Communications

• Make sure to use the communications distance, number of nodes connected, and method of con-

nection for EtherCAT within specifications.

Do not connect EtherCA

works. An overload may cause the network to fail or malfunction.

• Malfunctions or unexpected operation may occur for some combinations of EtherCAT revisions of

the master and slaves. If you disable the revision check in the network settings, use the Sysmac

Studio to check the slave revision settings in the master and the actual slave revisions, and then

make sure that functionality is compatible in the slave manuals or other references. You can check

the actual slave revisions from the Sysmac Studio or on slave nameplates.

• After you transfer the user program, the CPU Unit is restarted and communications with the Ether-

CAT slaves are cut off. During that period, the slave outputs behave according to the slave specifi-

cations. The time that communications are cut off depends on the EtherCAT network configuration.

Before you transfer the user program, confirm that the system will not be adversely affected.

T communications to EtherNet/IP, a standard in-house LAN, or other net-

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

• If the Fail-soft Operation Setting is set to Stop, process data communications will stop for all

slaves when an EtherCAT communications error is detected in a slave. At that time, the Servo Drive

will operate according to the Servo Drive specifications. Make sure that the Fail-soft Operation

setting

results in safe operation when a device error occurs.

• EtherCAT communications are not always established immediately after the power supply is turned

ON. Use the system-defined variables in the user program to confirm that communications are es-

tablished before attempting control operations.

• If noise occurs or an EtherCAT slave is disconnected from the network, any current communications

frames may be lost. If frames are lost, slave I/O data is not communicated, and unintended opera-

tion may occur. The slave outputs will behave according to the slave specifications. Refer to the

manual for the slave. If a noise countermeasure or slave replacement is required, perform the fol-

lowing processing.

a) Program the Input Data Invalid system-defined variable as an interlock condition in the user pro-

gram.

b) Set the PDO communications timeout detection count setting in the EtherCAT master to at

least 2. Refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No.

W505) for details.

• When an EtherCAT slave is disconnected, communications will stop and control of the outputs will

be lost not only for the disconnected slave, but for all slaves connected after it through to the physi-

cal end node. Confirm that the system will not be adversely affected before you disconnect a slave.

• I/O data communications of NX bus are not always established immediately after the power supply

is turned ON. Use the system-defined variables and the EtherCAT Coupler Unit device variables in

the user program to confirm that I/O data communications are established before attempting control

operations.

• You cannot use standard Ethernet hubs or repeater hubs with EtherCAT communications. If you use

one of these, a major fault level error or other error may occur.

• Confirm that all of the slaves are connected before you set the transmission delay time by the actual

measurement. If the transmission delay time is exceeded from the set values due to the changes of

the unit configuration, such as when the disabled salve is connected to the actual configuration after

the setting, it may cause illegal communications with slaves.

• When the communications cable that is connected to the slave from other manufacturers on the ring

topology is broken or the power supply to the slave from other manufacturers is interrupted, any cur-

rent communications frames may be lost.

If frames are lost, slave I/O data is not communicated, and unintended operation may occur.

When slaves from other manufacturers are connected on the ring topology, check the followings in

advance.

a) Disconnect and connect communications cables that are connected to the output ports of slaves

from other manufacturers several times, and there is no error except for a Ring Disconnection

Detected.

b) Disconnect and connect communications cables that are connected to the input ports of slaves

from other manufacturers several times, and there is no error except for a Ring Disconnection

Detected.

c) Turn OFF and ON the power supply to the slaves from other manufacturers, and there is no er-

ror except for a Illegal Slave Disconnection Detected.

• If you use the cable redundancy function, confirm that the task execution time is within the task peri-

od while the cable for the end port of the ring is disconnected. When a disconnection occurred on

• Confirm the axis number carefully before you perform an MC Test Run.

• The motor is stopped if communications are interrupted between the Sysmac Studio and the CPU

Unit during an MC T

Unit securely and confirm that the system will not be adversely affected before you perform an MC

Test Run.

• Always execute the Save Cam Table instruction if you change any of the cam data from the user

program in the CPU Unit or from the Sysmac Studio. If the cam data is not saved, the previous con-

dition will be restored when the power is turned ON again, possibly causing unexpected machine

operation.

• The positive drive prohibit input (POT), negative drive prohibit input (NOT), and home proximity in-

put (DEC) of the Servo Drive are used by the MC Function Module as the positive limit input, nega-

tive limit input, and home proximity input. Make sure that the signal widths for all of these input sig-

nals are longer than the control period of the MC Function Module. If the input signal widths are

shorter than the control period, the MC Function Module may not be able to detect the input signals,

resulting in incorrect operation.

• If you make any changes in the Detailed Settings Area of the Axis Basic Settings Display of the

Sysmac Studio, make sure that the devices or machines perform the expected operation before you

start actual operation.

If the relationship between the functions of the Motion Control Function Module and the EtherCAT

slave process data that is assigned to the axes is not correct, the devices or machines may perform

unexpected operation.

• Always use the axis at a constant velocity for the MC_DigitalCamSwitch (Enable Digital Cam

Switch) instruction.

If you set the Count Mode to Rotary Mode, the following operation will occur if you use OnCompen-

sation or OffCompensation and the axis velocity changes abruptly.

• If you change the unit conversion settings, perform homing again. If you do not perform homing, un-

intended operation of the controlled system may occur

Restoring Data

• You cannot back up, restore, or compare some or all of the settings for certain slaves and Units.

Also, you cannot back up, restore, or compare data for disabled slaves or Units. After you restore

data, sufficiently confirm that operation is correct before you start actual operation.

•

If any of the following conditions is met, clear the absolute encoder home offsets from the list of data

items to restore, and then restore the data. Then, define the absolute encoder home again. If you do

not define home, unintended operation of the controlled system may occur.

a) The Servomotor or Servo Drive was changed since the data was backed up.

b) The absolute encoder was set up after the data was backed up.

c) The absolute data for the absolute encoder was lost.

Transferring Programs

• When you use the program transfer from SD Memory Card whose Startup Mode setting is set to

RUN mode, the operating mode changes to RUN after the transfer is completed regardless of the

status and setting before the transfer. Use this function after you confirm that system startup does

not cause any problem.

•

Always confirm safety at the connected equipment before you perform the following operations

when the device output hold configuration is set to enable. The equipment may operate unexpected-

ly because the last status for outputs is retained.

a) Changing the operating mode of the CPU Unit

b) When downloaded

• When you transfer the values retained in the memory of the CJ-series Units, always check the set

values of the Device Output Hold Configuration and make sure that the destination is safe.

The devices or machines may perform unexpected operation regardless of the operating mode of

the CPU Unit.

Battery Installation and Replacement

• The Battery may leak, rupture, heat, or ignite. Never short-circuit, charge, disassemble, heat, or in-

cinerate the Battery or subject it to strong shock.

• Dispose of any Battery that has been dropped on the floor or otherwise subjected to excessive

shock. Batteries that have been subjected to shock may leak if they are used.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Safe Use

• Apply power for at least five minutes before changing the Battery. Install a new Battery within five

minutes (at 25°C) of turning OFF the power supply. If power is not supplied for at least 5 minutes,

the retained clock data may be initialized.

•

We recommend mounting or replacing the Battery with the power turned OFF to prevent the CPU

Unit’s sensitive internal components from being damaged by static electricity and to prevent mal-

functions. The Battery can be mounted or replaced without turning OFF the power supply. To do so,

always touch a grounded piece of metal to discharge static electricity from your body before you

start the procedure.

If the Low Battery Voltage error occurs after you mount the Battery, connect the Sysmac Studio and

clear the error.

Unit Replacement

• Make sure that the required data, including the user program, configurations, settings, and varia-

bles, is transferred to a CPU Unit that was replaced and to externally connected devices before re-

starting operation. Be sure to include the tag data link settings and routing tables, which are stored

in the CPU Unit.

• The absolute encoder home of

• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any

static build-up.

• Install the Controller away from sources of heat and ensure proper ventilation. Not doing so may re-

sult in malfunction, in operation stopping, or in burning.

Precautions for Correct Use

Mounting

• When you install the Unit, be careful not to touch or bump the pins in the NX bus connector.

• When you handle the Unit, be careful not to apply stress to the pins in the NX bus connector.

If the Unit is installed and the power supply is turned ON when the pins in the NX bus connector are

deformed, contact failure may cause malfunctions.

• Always mount an End Cover to the end of the CPU Rack to protect the last Unit on the CPU Rack.

Not mounting the End Cover may result in malfunction or failure of the CPU Unit.

• After you mount the Unit, always secure it with End Plates at both sides. If you do not secure it, the

Unit may be damaged or malfunction.

• If you use DIN Track Insulation Spacers to install a CPU Rack, the height will be increased by ap-

proximately 10 mm. Make sure that the CPU Rack and connecting cables do not come into contact

with other devices.

Wiring

• Do not allow foreign matter to enter the openings in the Unit. Doing so may result in Unit burning,

electric shock, or failure.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

Precautions for Correct Use

• Do not allow wire clippings, shavings, or other foreign material to enter any Unit. Otherwise, Unit

burning, failure, or malfunction may occur. Cover the Units or take other suitable countermeasures,

especially during wiring work.

•

For EtherCAT and EtherNet/IP, use the connection methods and cables that are specified in the

NJ/NX-series CPU Unit Built-in EtherCAT Port User’s Manual (Cat. No. W505) and the NJ/NX-series

CPU Unit Built-in EtherNet/IP Port User’s Manual (Cat. No. W506). Otherwise, communications may

be faulty.

• Use the rated power supply voltage for the Units that supply power. Take appropriate measures to

ensure that the specified power with the rated voltage and frequency is supplied in places where the

power supply is unstable.

• Make sure that the current capacity of the wire is sufficient. Otherwise, excessive heat may be gen-

erated. When cross-wiring terminals, the total current for all the terminals will flow in the wire. When

wiring cross-overs, make sure that the current capacity of each of the wires is not exceeded.

• If you use reed switches for the input contacts for AC Input Units, use switches with a current ca-

pacity of 1 A or greater.

If reed switches with smaller allowable currents are used, the contacts may fuse due to surge cur-

rents.

Replacing Slaves and Units

• If you replace a slave or Unit, refer to the operation manual for the slave or Unit for information on

the data required for individual slaves or Units and redo the necessary settings.

Task Settings

• If a Task Period Exceeded error occurs, shorten the programs to fit in the task period or increase the

setting of the task period.

Motion control

• Use the system-defined variable in the user program to confirm that EtherCAT communications are

established before you attempt to execute motion control instructions. Motion control instructions are

not executed normally if EtherCAT communications are not established.

•

Use the system-defined variables to monitor for errors in communications with the slaves that are

controlled by the motion control function module. Motion control instructions are not executed nor-

mally if an error occur in slave communications.

• Before you start an MC Test Run, make sure that the operation parameters are set correctly.

• Do not download motion control settings during an MC Test Run.

EtherCAT Communications

• If you need to disconnect the cable from an EtherCAT slave during operation, first disconnect the

software connection to the EtherCAT slave or disable the EtherCA

slaves that are connected after it.

Precautions for Correct Use

Battery Replacement

• Be sure to mount a Battery within two years of the production date shown on the Battery label.

• T

urn ON the power after replacing the Battery for a CPU Unit that has been unused for a long time.

Leaving the CPU Unit unused again without turning ON the power even once after the Battery is

replaced may result in a shorter Battery life.

• If you use the Battery, use the CJ1W-BAT01 Battery Set which is sold separately.

SD Memory Cards

• Insert the SD Memory Card all the way.

• Do not turn OFF the power supply to the Controller during SD Memory Card access. The files may

be corrupted.

If there is a corrupted file in the SD Memory Card, the file is automatically deleted by the restoration

function when the power supply is turned ON.

•

If you use an OMRON SD Memory Card, the end of the life of the SD Memory Card can be detected

in the following ways.

a) _Card1Deteriorated (SD Memory Card Life Warning Flag) system-defined variable

b) SD Memory Card Life Exceeded event in the event log

When the end of the life is detected in any of the above ways, replace the SD Memory Card.

Online Editing

• When performing online editing, the CPU Unit saves a program updated by the online editing to

built-in non-volatile memory. Sysmac Studio shows a message that it is in a backup operation. Do

not turn OFF the power supply to the Controller while this message is displayed. If the power supply

to the Controller is turned OFF

next time.

, a Controller error will occur when the power supply is turned ON

Debugging

• If you use data tracing to sample following variables, correct data may not be sampled.

a) Structure members whose data size is 16 bits or more, except for system-defined variables for

motion control

b) Array elements whose data size is 16 bits or more

• For information on data tracing, refer to the NJ/NX-series CPU Unit Software User

EMC Directives

OMRON devices that comply with EU Directives also conform to the related EMC standards so that

they can be more easily built into other devices or the overall machine. The actual products have

been checked for conformity to EMC standards.*1

Whether the products conform to the standards in the system used by the customer, however, must

be checked by the customer. EMC-related performance of the OMRON devices that comply with

EU Directives will vary depending on the configuration, wiring, and other conditions of the equip-

ment or control panel on which the OMRON devices are installed. The customer must, therefore,

perform the final check to confirm that devices and the overall machine conform to EMC standards.

*1. Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Suscept-

• NX-series Units that comply with EU Directives also conform to the Common Emission Standard.

Radiated emission characteristics (10-m regulations) may vary depending on the configuration of

the control panel used, other devices connected to the control panel, wiring, and other condi-

tions.

You must therefore confirm that the overall machine or equipment in which the NX-series Units

The NX-series Controller

The SYSMAC NX-series are next-generation machine automation controllers that provide the function-

ality and high-speed performance that are required for machine control. They provide the safety, relia-

bility, and maintainability that are required of industrial controllers.

The NX-series Controllers provide the functionality of previous OMRON PLCs, and they also provide

the functionality that is required for motion control. Synchronized control of I/O devices on high-speed

EtherCAT can be applied to safety devices, vision systems, motion equipment, discrete I/O, and more.

Especially, the NX-series NX1P2 Controller can perform I/O operation with a mounted NX Unit or Op-

tion Board, and with the built-in I/O.

OMRON offers the new Sysmac Series of control devices designed with unified communications spec-

ifications and user interface specifications. The NX-series Machine Automation Controllers are part of

the Sysmac Series. You can use them together with EtherCAT slaves, other Sysmac products, and the

Sysmac Studio Automation Software to achieve optimum functionality and ease of operation.

With a system that is created from Sysmac products, you can connect components and commission

the system through unified concepts and usability.

Features

Hardware Features

Standard-feature EtherCAT Control Network Support

All CPU Units provide an EtherCAT master port for EtherCAT communications.

EtherCAT is an advanced industrial network system that achieves faster

cations. It is based on Ethernet. Each node achieves a short fixed communications cycle time by

transmitting Ethernet frames at high speed.

The standard-feature EtherCAT control network allows you to connect all of the devices required

for machine control (e.g., I/O systems, Servo Drives, Inverters, and machine vision) to the same

network.

Support for EtherCAT Slave Terminals

You can use EtherCAT Slave Terminals to save space. You can also flexibly build systems with the

wide variety of NX Units.

Achieving a Safety Subsystem on EtherCAT

You can use NX-series Safety Control Units to integrate safety controls in a sequence and motion

control system as a subsystem on EtherCAT.

, more-efficient communi-

1-1-1 Features

Standard-feature EtherNet/IP Communications Port

A CPU Unit provides an EtherNet/IP communications port for EtherNet/IP communications as a

standard feature.

EtherNet/IP is a multi-vendor industrial network that uses Ethernet. You can use it for networks be-

tween Controllers or as a field network. The use of standard Ethernet technology allows you to con-

nect to many different types of general-purpose Ethernet devices.

Built-in I/O Available

The Controller has the built-in I/O. You can connect small I/O devices inside the control panel at a

low cost.

NX-series Units Connectable

Up to eight NX Units including NX-series Digital I/O Units, Analog I/O Units, and other I/O Units can

be connected to the CPU Unit.

Precautions for Correct Use

You cannot mount NX-series Safety Control Units on the CPU Unit and use them. Use NX-series Safety Control Units as a subsystem on EtherCAT

Option Boards Connectable

One or two Option Boards to add the serial communications or analog I/O function can be connect-

ed to the CPU Unit.

The Serial Communications Option Board enables you to connect general-purpose components

such as a bar code reader.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

1-3

1 Introduction to NX-series Controllers

The Analog I/O Option Board allows inputs from devices such as variable resistors, process-control

sensor, and inverter control.

Battery-free Operation

The following data (other than the clock data) is retained in the built-in non-volatile memory.

• User program

•

Set values

• Variables retained during power interruption

• Event logs

The retention period for the clock data is limited*1.

When the clock data is not needed or the equipment’s power OFF time is shorter than the clock

data retention period, the battery-free operation is possible and man-hours for battery replacement

can be reduced.

If you turn OFF the power supply to the equipment for a longer period of time than the clock data

retention period, mount a battery which is sold separately.

*1. Approximately 10 days at an ambient temperature of 40°C. Refer to 3-1-5 Battery on page 3-18 for detail.

Standard-feature SD Memory Card Slot

You can access an SD Memory Card that is mounted in the CPU Unit from the user program.

Highly Reliable Hardware

The NX-series Controllers provide the hardware reliability and RAS functions that you expect of a

PLC.

Software Features

Integrated Sequence Control and Motion Control

An NX-series CPU Unit can perform both sequence control and motion control. You can simultane-

ously achieve both sequence control and multi-axes synchronized control. Sequence control, mo-

tion control, and I/O refreshing are all executed in the same control period.

The same control period is also used for the process data communications cycle for EtherCAT

enables precise sequence and motion control in a fixed period with very little deviation.

Programming Languages Based on the IEC 61131-3 International Standard

The NJ-series Controllers support language specifications that are based on IEC 61131-3. To

these, OMRON has added our own improvements. Motion control instructions that are based on

. This

1-4

PLCopen® standards and an instruction set (POUs) that follows IEC rules are provided.

Programming with Variables to Eliminate Worrying about the Memory Map

You access all data through variables in the same way as for the advanced programming languag-

es that are used on computers. Memory in the CPU Unit is automatically assigned to the variables

that you create so that you do not have to remember the physical addresses.

A Wealth of Security Features

The many security features of the NX-series Controllers include operation authority settings and re-

striction of program execution with IDs.

NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

1 Introduction to NX-series Controllers

Complete Controller Monitoring

The CPU Unit monitors events in all parts of the Controller, including mounted NX Units and Ether-

CAT slaves.

roubleshooting information for errors is displayed on the Sysmac Studio or on an NS-series PT.

Events are also recorded in logs.

Sysmac Studio Automation Software

The Sysmac Studio provides an integrated development environment that covers not only the Con-

troller, but also covers peripheral devices and devices on EtherCAT. You can use consistent proce-

dures for all devices regardless of the differences in the devices. The Sysmac Studio supports all

phases of Controller application, from designing through debugging, simulations, commissioning,

and changes during operation.

A Wealth of Simulation Features

The many simulation features include execution, debugging, and task execution time estimates on

a virtual controller.

Basic System Configuration

An NX-series Controller NX1P2 supports the following two types of configurations.

• Basic Configuration

The basic configurations include the CPU Unit and the Configuration Units that are controlled direct-

ly by the CPU Unit. There are two basic configurations.

a) EtherCAT network configuration

b) NX Unit configuration

• Other Network Configurations

These are the configurations of the systems that are connected to the CPU Unit’s built-in

EtherNet/IP ports and Communications Units.

Basic Controller Configuration

EtherCAT Network Configuration

With an NX-series CPU Unit, you can use an EtherCAT network as a basic system.

With the EtherCAT network system of the NX-series CPU Unit, the period for sequence processing

and motion processing in the CPU Unit is the same as the EtherCAT communications period.

This enables high-precision sequence control and motion control with a constant period and little

fluctuation.

For information on EtherCAT, refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port User’s

Manual (Cat. No. W505).

NX Unit Configuration

The CPU Rack consists of the following items.

• NX1P2 CPU Unit

• NX Unit NX-£££££££

• End Cover NX-END02

Up to eight NX Units can be connected.

By using the NX Units that support synchronous I/O refreshing, all I/O refreshing is synchronized

with the task period of the primary periodic task of the CPU Unit.

This enables high-precision synchronized control with a stable fixed period.

Precautions for Safe Use

• Never turn OFF the power supply to the Controller when the BUSY indicator is flashing. While the BUSY indicator is lit, the user program and settings in the CPU Unit in the built-in non-volatile memory. The data will not be backed up if the power supply is turned OFF. Also, a major fault level Controller error will occur the next time you start operation, and operation will stop.

• Do not turn OFF the power supply or remove the SD Memory Card while SD Memory Card access is in progress (i.e., while the SD BUSY indicator flashes). Data may become corrupted, and the Controller will not operate correctly if it uses corrupted data. To remove the SD Memory Card from the CPU Unit while the power supply is ON, press the SD Memory Card power supply switch and wait for the SD BUSY indicator and SD PWR indicator to turn OFF before you remove the SD Memory Card.

You can check the operation status of the CPU Unit with the CPU Unit status indicators (POWER,

RUN, and ERROR indicators).

ou need to prepare a battery for the CPU Unit to retain the clock data while the CPU Unit is left pow-

ered of

The following describes the purpose of the battery mounting, the battery model, and the battery-relat-

ed error detection and clock data settings.

Purpose of the Battery Mounting

The battery is used to retain the clock data while the power is not supplied to the CPU Unit. The clock

data is retained by the built-in capacitor whether the battery is mounted or not, but the retention period

depends on the continuous power-ON time of the CPU Unit, as shown below.

Retention period

*1. This is equivalent to the time to charge a built-in capacitor in which no electric charge is accumulated.

during no power supply at an ambient temperature of

40°C

When you use the clock data for programming, use a battery if you cannot ensure the continuous pow-

er-ON time shown above or the power-OFF time is longer than the above power-ON time.

The following data (other than the clock data) is retained in the built-in non-volatile memory, so they

are not lost even if the battery and built-in capacitor are fully discharged.
