1-1 Overview of NJ/NX-series Errors
You manage all of the errors that occur on the NJ/NX-series Controller as events. The same methods are used for all events. This allows you to see what errors have occurred and find corrections for them with the same methods for the entire range of errors that is managed (i.e., CPU Unit, NX Units, NXseries Slave Terminals, EtherCAT slaves,*1 and CJ-series Units). *1. Only Sysmac devices are supported. For information on EtherCAT slaves that are Sysmac devices, refer to

1-1-1 Types of Errors
There are two main types of errors (events) depending on whether the NJ/NX-series can manage them or not.
l Fatal Errors
These errors are not detected by the event management function of the NJ/NX-series because the CPU Unit stops operation. You cannot identify or reset these errors with the Sysmac Studio or an HMI.
Refer to 1-2 Fatal Errors on page 1-9 for error types and confirmation methods of fatal errors in the CPU Unit.
l Non-fatal errors
These errors are detected and managed with the event management function of the NJ/NX-series. You can confirm these errors with the Sysmac Studio or an HMI.

1 Overview of Errors
1-3 Non-fatal Errors
1-3-1 Types of Non-fatal Errors
Non-fatal errors that occur in the NJ/NX-series Controller are managed as events. You can check the event to find out what type of error occurred.
l Controller Events
The Controller automatically detects these events. Controller events include events for the function modules in the CPU Unit, NX Units, NX-series Slave Terminal, EtherCAT slaves, and CJ-series Units.
Additional Information · You cannot check the error logs that are managed independently by EtherCAT slaves on Sys-
mac Studio because they are not for Controller events. Refer to relevant manuals for the slaves for the procedures to read error logs and correct errors. · Error causes and corrections are not displayed on the Controller Event Log Tab Page in the Sysmac Studio, although error codes, which are registered in the error logs that are managed independently by CJ-series Special Units, are displayed. Refer to relevant manuals for the Units for the procedures to read error logs and correct errors.
l User-defined Events
These are events that occur in applications that the user developed.
This manual does not describe user-defined events. Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for information on user-defined events.
Overview of Controller Events (Errors and Information)
You use the same methods to manage all of the events that occur on the NJ/NX-series Controller. The events that occur are saved in the CPU Unit or NX-series Slave Terminals. You can use the Sysmac Studio or an HMI to confirm current Controller events and the log of events that occurred before. This log is called an event log. To use an HMI to check events, connect the HMI to the built-in EtherNet/IP port on the CPU Unit.
The event management for NX-series Units is shown below.

Additional Information
For an NX-series or NJ-series CPU Unit, use the following information to handle errors that occurred in an EtherCAT Slave Terminal or EtherCAT slave. · Refer to the manual for the Communications Coupler Unit for details on the event log in a
Slave Terminal. · When there is an emergency message that notifies an error from an EtherCAT slave to the
CPU Unit, it is recorded in the event log of the EtherCAT Master Function Module as the Emergency Message Detected (64200000 hex) event. · You cannot confirm the event log for an EtherCAT slave that has no event log. To record an error history as an event, you have to change the setting of the EtherCAT slave to notify emergency messages, then the Emergency Message Detected (64200000 hex) event is recorded. However, errors which cannot be notified by emergency messages from EtherCAT slaves are not recorded in the event log. Meanwhile, there is a way to display error history of some EtherCAT slaves that do not have the event log, on the Sysmac Studio version 1.15 or higher as the event log. Refer to relevant manuals for EtherCAT slaves for the possibility to display error history as the event log. · Refer to relevant manuals for the slaves for the procedures to read error history of EtherCAT slaves.

Details on Controller Events (Errors and Information)

l Controller Event Times

The time of occurrence is recorded when an event occurs.

The times of occurrence are based on the CPU Unit's built-in clock data.

For events that occur in EtherCAT Slave Terminals, the times of occurrence are recorded based on

the CPU Unit's built-in clock data that the EtherCAT Slave Terminal receives from the CPU Unit.

If the EtherCAT Slave Terminal cannot obtain the clock data from the CPU Unit, the time of occur-

rence on the Sysmac Studio is displayed as ----/--/-- --:--:--. For an event occurred before the Ether-

CAT Slave Terminal obtains the clock data from the CPU Unit, the time of occurrence is also dis-

played as ----/--/-- --:--:--.

The time of occurrence for an event is displayed on the Sysmac Studio or HMI.

Version Information
If the EtherCAT Slave Terminal cannot obtain the clock data from the CPU Unit or an event occurred before the EtherCAT Slave Terminal obtains the clock data from the CPU Unit, the time of occurrence is displayed as 1970/1/1 0:00:00 with Sysmac Studio version 1.14 or lower.

l Sources of Controller Events
The Event source information indicates the location where an event occurred. The event source identifies the particular function module in the CPU Unit in which the event occurred. For some function modules, there is more detailed information about the event source. This information is called the Source details. The following information is provided as the event source details.

Errors with a higher level have a greater impact on the functions that the NJ/NX-series Controller provides, and are more difficult to recover from. When an event occurs, the Sysmac Studio or HMI will display the level name.

Each event level is described below.

Level Major fault level
Partial fault level
Minor fault level Observations Information

Description
These errors prevent control operations for the entire Controller. When the CPU Unit detects a major fault, it immediately stops the execution of the user program and turns OFF the loads of all slave, including remote I/O. With EtherCAT slaves, some NX Units, and some CJ-series Special Units, you can set the slave settings or Unit settings to select whether outputs will go OFF or retain their previous status. You cannot reset major fault level errors from the user program, the Sysmac Studio or an HMI.You cannot reset major fault level errors from the user program, the Sysmac Studio or an HMI. To recover from a major fault level error, remove the cause of the error, and either cycle the power supply to the Controller, or reset the Controller from the Sysmac Studio.
These errors prevent control operations in a certain function module in the Controller. The NJ/NX-series CPU Unit continues to execute the user program even after a partial fault level error occurs. You can include error processing in the user program in order to stop equipment safely. After you remove the cause of the error, execute one of the following to return to normal status. · Reset the error from the user program, the Sysmac Studio, or an HMI. · Cycle the power supply. · Reset the Controller from the Sysmac Studio.
These errors prevent part of the control operations in a certain function module in the Controller. The troubleshooting for minor fault level errors is the same as the processing for partial fault level errors.
These errors do not affect the control operations of the Controller. The observation notifies you of potential problems before they develop into a minor fault level error or worse.
Events that are classified as information provide information that do not indicate errors.

Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for information on system-defined variables.

Checking Communications Status with the Network Configurator

You can use the Network Configurator to check the communications status (e.g., tag data link connec-

tion status) for each device on the EtherNet/IP network. For details, refer to the methods of communi-

cations status check and troubleshooting for the EtherNet/IP network described in the NJ/NX-series

CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506).

Checking with the EtherCAT Diagnostic and Statistical Information on the Sysmac Studio
With the Sysmac Studio, you can check the statistical information such as the number of communications frames on the EtherCAT network as well as the number of frames for which errors were detected. For details, refer to the diagnosis and statistics information for EtherCAT described in the NJ/NXseries CPU Unit Built-in EtherCAT Port User's Manual (Cat. No. W505).

1-3-2 Checking for Non-fatal Errors

NJ/NX-series Troubleshooting Manual (W503)

1-29

1 Overview of Errors
1-3-3 Resetting Non-fatal Errors
Unless you reset an error, the Controller will retain the error status until you turn OFF the power supply to the Controller or reset the Controller. To reset a Controller error, it is necessary to eliminate the cause of the error. The same error will occur again if you reset the error, but do not eliminate the cause of the error.
Precautions for Safe Use
· 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 (in which outputs are disabled) due to the Controller error with an event level of partial fault or higher will go to Operational state and the outputs will be enabled. Before you reset all errors, confirm that no Controller errors with an event level of partial fault have occurred for the EtherCAT Master Function Module.
· Always confirm safety at the connected equipment before you reset Controller errors for a CJ-series Special Unit. When a Controller error is reset, the Unit where the Controller error with an event level of observation or higher will be restarted. Before you reset all errors, confirm that no Controller errors with an event level of observation or higher have occurred for the CJ-series Special Unit. Observation level events do not appear on the Controller Error Tab Page, so it is possible that you may restart the CJ-series Special Unit without intending to do so. You can check the status of the _CJB_UnitErrSta[0,0] to _CJB_UnitErrSta[3,9] error status variables on a Watch Tab Page to see if an observation level Controller error has occurred.
Precautions for Correct Use
Resetting an error is not the same as eliminating the cause of the error. Always eliminate the cause of an error before you perform the procedure to reset the error.

The following Motion Control Function Module error can occur due to errors in EtherCAT communications, EtherCAT slaves, or NX Units.

Error name

Event code

Cause

Operation for error

EtherCAT Slave Communications Error

8440 0000 hex

A communications error occurred for the EtherCAT slave or NX Unit that is allocated to an axis in the Motion Control Function Module. *1

The Servo is turned OFF for the axis with an error and operations other than error resets are not acknowledged. *2

Slave Error Detected

742F 0000 hex

An error was detected for the EtherCAT slave or NX Unit that is allocated to an axis in the Motion Control Function Module.

The Servo is turned OFF for the axis with an error and operations other than error resets are not acknowledged.

*1. When an error occurs in communications with an EtherCAT slave, an error also occurs in the EtherCAT Master Function Module. If you assign more than one device to the same axis, a communications error occurs for the axis if a communications error occurs for even one of the devices.
*2. When an error occurs in slave communications, home becomes undefined for the axis.

Servo Drive Errors
This section describes the notification that is provided for errors that occur in OMRON 1S-series Servo Drives and G5-series Servo Drives.

NJ/NX-series Troubleshooting Manual (W503)

1-35

1 Overview of Errors
There is a difference between the timing of when the Motion Control Function Module detects the error in the Servo Drive and when the error code is obtained from the Servo Drive. The Motion Control Function Module therefore reports different events for the error in the Servo Drive and the error code.
l Error Notification
When the Motion Control Function Module detects an error, a Slave Error Detected minor fault level error (742F0000 hex) occurs. At this point, the Motion Control Function Module performs the error operation (i.e., it turns OFF the Servo).
l Error Code Notification
When the Servo Drive reports the error code, the Motion Control Function Module generates a Slave Error Code Report information event (94220000 hex). The error code (the main part of the error display number) from the Servo Drive is included in the lower two digits of the attached information of the Slave Error Code Report event. For example, if the attached information is displayed as FF13, the error with display number 13 (Main Circuit Power Supply Undervoltage) occurred in the Servo Drive.
Precautions for Correct Use You must change the settings to receive notification of the Slave Error Code Report event. Map object 603F hex (Error Code) in the PDO Edit Pane.
Errors Related to NX Units
Error and error code notifications are provided for errors that occur for OMRON NX-series Position Interface Units in the same way as they are for OMRON 1S-series Servo Drives and G5-series Servo Drives.
However, NX-series Position Interface Units do not have an object that corresponds to object 603F hex (Error Code), so 0000 hex is given for the Slave Error Code Report (94220000 hex) in the attached information.
Refer to the NX-series Position Interface Units User's Manual (W524) or the NX-series EtherCAT Coupler Unit User's Manual (Cat. No. W519) for details on errors that occur in NX-series Position Interface Units.

1 Overview of Errors

l Resetting Errors in the EtherCAT Master Function Module
Before you reset the following errors, always make sure that the slave with the error is participating in the network. · Resetting a Network Configuration Verification Error or Process Data Communications Error
while the power supply to the slave is ON or while the cable is connected · Resetting a Link OFF Error while the power supply is ON to the first slave where the cable was
disconnected or while the cable is connected
Use the following procedure.
START

· Power to NJ/NX-series Controller turned ON?

· Data downloaded to NJ/NX-series Controller (master restarted)?

· Or, master link status changed from Link OFF to Link ON?*1

Yes
Wait time exceeded? No
Yes

Target slave participating?*2 No
Yes
Reset error in EtherCAT Master Function Module.

END
*1. Check the _EC_LinkStatus (Link Status) system-defined variable. *2. Check the _EC_EntrySlavTbl[] (Network Connected Slave Table) system-defined variable.
Also, set the wait time for slave startup in the EtherCAT master settings (EtherCAT master parameter settings) long enough to allow for the power supply startup time of all of the slaves.
If you reset the error in the EtherCAT Master Function Module without using the above procedure, the EtherCAT master may access a slave with a different node address than the specified node address, or other unexpected operations may occur. Also, the error may not be reset correctly.
l Resetting Slave Errors
You can reset errors in the EtherCAT Master Function Module to reset slave errors. However, process data communications between the EtherCAT master and EtherCAT slave must be active to reset a slave error. If process data communications with the slave are not active, check the slave after you reset errors in the EtherCAT Master Function Module to see if process data communications are active. Then, to reset the error in the slave, reset errors in the EtherCAT Master Function Module again.

1 Overview of Errors

Precautions When Connecting or Disconnecting Slaves during Communications
This section describes the procedure and precautions for replacing a slave that is currently performing communications.

l Procedure for Disconnecting Slaves during Communications
Always use the following procedure to turn OFF the slave power supply or disconnect cables dur-

ing EtherCAT master communications.*

* This includes the safe-operational and operational states.

Step 1: Use the Sysmac Studio or an instruction to send a command to disconnect the slave. Step 2: Confirm that the slave was disconnected normally. Step 3: Turn OFF the power supply to the slave or disconnect the cable.

If you turn OFF the power supply or disconnect the cable without performing steps 1 and 2, the slaves that are operating may be adversely affected.
l Prohibition to Physically Disconnecting a Slave and Resetting an Error or Connecting a Slave at the Same Time
If you perform the following operation (a) or (b) at the same time as operation (c), an error will occur. a. Turn OFF the power supply to the slave or disconnect the cable. b. Turn ON the power supply to the slave or connect the cable. c. Reset an error in the EtherCAT Master Function Module or connect the slave.* * This can happen when the Reset EtherCAT Error (ResetECError) instruction or Connect EtherCAT Slave (EC_ConnectSlave) instruction is cyclically executed in the user program.

If you perform these operations at the same time, the EtherCAT master may access a slave with a different node address than the specified node address, or other unexpected operations may occur. Therefore, never turn OFF the power supply to the slave or disconnect the cable at the same time as you reset an error or connect a slave.

2-1 Troubleshooting Flowcharts

This section provides basic error identification and troubleshooting flowcharts. Use them when an error occurs in the NJ/NX-series Controller.

2-1-1 Checking to See If the CPU Unit Is Operating
When an error occurs in the NJ/NX-series Controller, use the following flowchart to determine whether the error is a fatal error or a non-fatal error.

Whenever possible, set the Sysmac Studio's software connection method in the flowchart to a direct USB connection if the CPU Unit has a USB (peripheral) port. If you use Ethernet, there are many reasons that prevent a communications connection for the Sysmac Studio, so time is required to determine if a fatal or non-fatal error has occurred. If you cannot go online from the Sysmac Studio, perform 2-4 Troubleshooting When You Cannot Go Online from the Sysmac Studio on page 2-23 before you assume that the error is a fatal error.

2-4 Troubleshooting When You Cannot Go Online from the Sysmac Studio

The section describes the procedure to troubleshoot when you cannot go online with the CPU Unit from the Sysmac Studio.

2-4-1 Causes and Correction When You Cannot Go Online from the

Sysmac Studio

The following table lists the possible causes when you cannot go online with the CPU Unit from the

Sysmac Studio.

Cause Incorrect settings or faulty communications path
Fatal error in the CPU Unit High system service load*1
Incorrect settings of Packet Filter in TCP/IP Settings*2

Description
There is a mistake in the settings that the Sysmac Studio uses to go online with the CPU Unit. Or, the communications path is faulty.
A fatal error occurred in the CPU Unit.
The system service load on the CPU Unit is too high and time cannot be obtained to connect with the Sysmac Studio.
The Packet Filter is enabled and you attempt to connect the Sysmac Studio from the computer with unregistered IP address to allow connection.

*1. This applies to an NJ-series CPU Unit. *2. This applies to an NX102 CPU Unit only.

Correction Refer to Troubleshooting Incorrect Settings and Faulty Communications Path on page 2-25 in 2-4-2 Troubleshooting for Each Cause on page 2-25
Refer to 2-1-1 Checking to See If the CPU Unit Is Operating on page 2-2. Start in Safe Mode. Refer to Troubleshooting a High System Service Load on page 2-30 in 2-4-2 Troubleshooting for Each Cause on page 2-25
You can disable Packet Filter tentatively by starting in the Safe Mode. Connect the Sysmac Studio after you start in Safe Mode, and then review the Packet Filter settings. Refer to Troubleshooting Incorrect Settings of Packet Filter in TCP/IP Settings on page 2-31 in 2-4-2 Troubleshooting for Each Cause on page 2-25 for details.

Note If the EtherNet/IP NET ERR indicator on the CPU Unit is lit or flashing, it is possible that you cannot go online through an EtherNet/IP route because of an error in the EtherNet/IP Function Module. If the CPU Unit has a peripheral (USB) port, see if you can go online with a direct USB connection. If the CPU Unit does not have a peripheral (USB) port, see if you can go online with a direct Ethernet connection.

Precautions for Correct Use
· If you connect an NX-series CPU Unit to the Sysmac Studio through an EtherNet/IP port, connect to communications port 1. You cannot connect the Sysmac Studio directly to communications port 2.
· For an NX102 CPU Unit, you cannot connect the Sysmac Studio installed on the computer with unregistered IP address to allow connection if Packet Filter is set to enable. Confirm that the IP address of the computer to allow connection is registered correctly in advance.
· For an NX102 CPU Unit, you cannot connect the Sysmac Studio to the CPU Unit in Direct connection via Ethernet if Packet Filter is enabled. Select Controller - Communications Setup to confirm that the connection method is Ethernet connection via a hub.

2 Error Troubleshooting Methods

Troubleshooting a High System Service Load
In the NJ-series CPU Unit, a high throughput in task execution may cause the system service to enter a high-load state, and this may prevent the Sysmac Studio from connecting with the CPU Unit. If a high system service load is the problem, you will be able to go online with the CPU Unit from the Sysmac Studio if you start in Safe Mode. Use the following procedure.
1 Set on the DIP switch on the CPU Unit as shown below and then cycle the power supply to the
Controller. The CPU Unit will start in Safe Mode.

Turn OFF.

Turn ON.

2 Go online with the CPU Unit from the Sysmac Studio and perform the required operation.
Ensure that there is sufficient system service time to enable the Sysmac Studio to go online with the CPU Unit. To do so, either increase the period of the primary periodic task or decrease the sizes of the programs in the primary periodic task. Refer to the NJ/NX-series CPU Unit Software User's Manual (Cat. No. W501) for information on setting the primary periodic task.
3 Turn OFF all DIP switch pins and then cycle the power supply to the Controller to restore nor-
mal CPU Unit operation.
l Safe Mode Operation
If the Controller is started when the CPU Unit is in Safe Mode, the CPU Unit will start in PROGRAM mode even if the startup mode is set to RUN mode. This increases the ratio of system service processing that is performed by the CPU Unit, which makes it easier for the Sysmac Studio to go online with the CPU Unit. You can also use Safe Mode when you do not want to execute the user program. The CPU Unit will generate an observation level Controller event and record a Safe Mode event in the event log.

Troubleshooting Incorrect Settings of Packet Filter in TCP/IP Settings
In the NX102 CPU Unit, if the settings of Packet Filter in TCP/IP Settings are not correct, you cannot connect the Sysmac Studio to the CPU Unit. If you start in Safe Mode and disable the Packet Filter tentatively, you can connect the Sysmac Studio to the CPU Unit. Perform the following procedure and review the Packet Filter settings.
1 Set on the DIP switch on the CPU Unit as shown below and then cycle the power supply to the
Controller. The CPU Unit will start in Safe Mode.

OFF

2 Go online with the CPU Unit from the Sysmac Studio and review the Packet Filter settings.
Confirm that the IP address of the computer that is installed the connected Sysmac Studio is registered. If the IP address is not registered, you must register the IP address. Refer to Packet Filter (NX102 CPU Unit) under TCP/IP Settings Display in the NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506).
3 Turn OFF all DIP switch pins and then cycle the power supply to the Controller to restore nor-
mal CPU Unit operation.
4 Confirm that the connection method of the Sysmac Studio is Ethernet connection via a hub and
then confirm whether you can go online to the CPU Unit. Select Controller - Communications Setup to confirm that the connection method is Ethernet connection via a hub. If Packet Filter is enabled, you cannot connect the Sysmac Studio in Direct connection via Ethernet.

Cause and correction

Assumed cause
The Controller power supply was turned OFF while the BUSY indicator was lit.
The power supply to the Controller was interrupted momentarily while the BUSY indicator was lit.

Correction
Compare the project with the project on the Sysmac Studio. If they match, cycle the power supply to the Controller or reset the Controller to see if that clears the error. If the error is cleared, check that the device operates correctly. If the comparison shows a mismatch, if the error is not cleared, or if the device does not operate correctly, clear all of memory and then download the project from the Sysmac Studio again. If cycling the power supply to the Controller or resetting the Controller does not clear the error, the memory is corrupted. Replace the CPU Unit. Unexpected operation may occur and can be very dangerous if the power to the Controller is cycled or the Controller is reset before you download the project again.

Prevention Do not turn OFF the power supply while the BUSY indicator is lit.
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.

Motion Control Instructions
This section provides a table of errors (events) that occur for motion control instructions. The upper four digits of the event code give the error code (ErrorID) for the motion control instruction. For descriptions of an error code, refer to the description of the corresponding event code. For example, if the error code for the motion control instruction is 16#3461, refer to the description for event code 34610000 hex.
Precautions for Correct Use
With CPU Unit with unit version 1.10 or later, a variable name that starts with _MC_AX[*] may start with _MC1_AX[*] or _MC2_AX[*] instead. In the same way, a variable name that starts with _MC_GRP[*] may start with _MC1_GRP[*] or _MC2_GRP[*] instead.

3-4-3 Other Troubles and Corrections

3 Error Descriptions and Corrections

3-4-3 Other Troubles and Corrections
This section describes remedial actions to take when problems occur the first time you use the MC Function Module or after starting operation.

Preliminary Check Items

If an error occurs, check the items below to investigate the problem.

Category

Item to check

Installation conditions Is there dust in the ambient environment?

Are there conductive foreign matters (metal, carbon, etc.) in the ambient environment that might enter the Controller?

Is the ambient temperature higher than the ambient operating temperature in the speci-

fications?

Is the ambient area humid (due to moisture in the air, use of water, etc.)?

Does the ambient air contain corrosive gases (acid, salt, sulfur, etc.)?

Are there sources of noise around the Controller (welders, inverters, etc.)?

Wiring

Are power supply lines wired in the same duct as the signal lines?

Is the Controller grounded properly?

Is there a noise filter in the power supply?

Changes

Was any extension work (welding work) done lately?

Was any power supply facility added lately?

Was the system (including its program) modified in any way (including additions)?

Accidents

Was there a lightning strike nearby?

Was there a ground-fault accident or was the earth leakage breaker tripped?

Was there a power outage?

Problems and Countermeasures

This section describes troubleshooting when the MC Function Module is used in combination with an OMRON 1S-series Servo Drive or G5-series Servo Drive. If an unexpected operation is performed, data such as parameter settings or cam data may not have been transferred properly to the CPU Unit from the Sysmac Studio. Furthermore, variables may not be working properly between the user program and the MC Function Module. Use the data tracing function of Sysmac Studio to check if variables are exchanged at the correct timings.

Problem
Motor does not lock.

Cause
The MC Function Module does not output operation commands to the Servo Drive.
Servo Drive setting error

Item to check Make sure that you execute the MC_Power instruction.
Check the Servo Drive settings.

Countermeasure Correct the program.
Set the Servo Drives correctly.

NJ/NX-series Troubleshooting Manual (W503)

3-549

3 Error Descriptions and Corrections

Problem Motor does not run.
Homing cannot be performed.
The position of home defined with homing changes occasionally.

Cause The drive prohibit input of the Servo Drive is enabled.
Servo Drive error
Mechanical axis is locked.
CPU Unit failure Error
Incorrect wiring of the home proximity input.
Incorrect wiring of the home input. The rotation direction and limit input direction are inconsistent.
Incorrect wiring of the limit input InPosWaiting does not change to FALSE.
Homing approach velocity is too high.
Axis parameters are not set correctly.
CPU Unit failure Loose mechanical parts, such as couplings
Insufficient leeway for Z phase Insufficient leeway for home input signal

Item to check Use the Servo Drive software to check the drive prohibit input.
Check for a Servo Drive error.
Check for contact with mechanical limits and check to see if mechanical parts are caught on something. --Check the nature of the error.
Check the axis input information in the Axis Variables to see if the home proximity input sensor turns ON/OFF. Check the wiring of the home input. If the axis moves to the mechanical limit without reversing at the limit, check the axis input information in the Axis Variables to see if the limit input turns ON and OFF. Check the wiring of the limit inputs. Check to see if the Servo Drive gain is too low. Check to see if the in-position range is too narrow. Check the homing approach velocity.
Check the axis parameters in the Sysmac Studio.
--Use a marker pen to mark the motor shafts, couplings, and other mechanical connections to check for shifting. If the value is close to the setting per Servomotor rotation (number of pulses per encoder rotation) or near zero, the home may be shifted by one motor rotation due to slight changes in the timing of reading the sensor input.

Countermeasure Cancel the drive prohibit input of the Servo Drive. Change the setting so that you do not use the drive prohibit input of the Servo Drive. If there is an error, follow troubleshooting procedures for it. Manually release the locked mechanical axis.
Replace the CPU Unit. If there is an error, follow troubleshooting procedures for it. Wire all connections correctly.
Wire all connections correctly.
Wire the limit inputs correctly.
Wire all connections correctly.
Increase the Servo Drive gain. Increase the in-position range. Lower the homing approach velocity of the MC Function Module. After setting the axis parameters correctly, download them to the MC Function Module. Replace the CPU Unit. Securely tighten the connections that shifted.
Remove the motor coupling and shift the position by around one-quarter of a turn so that the Z phase pulse occurs at around one half of a Servomotor rotation (number of pulses per encoder rotation), and then perform homing again.

Manually adjust the Servomotor gain.

Incorrect Servomotor selection (adjustment not possible)

Select another motor (check the Change to an optimal motor. torque and inertia ratio).

Damaged Servomotor bearings

Turn OFF the Servo Drive power supply, and also turn ON the brake power supply and release the brake if the motor comes with a brake. Then manually turn the motor output shaft with the motor power line disconnected (because the dynamic brake may be applied).

Replace the Servomotor.

Broken Servomotor winding

Use a tester to check the resistance between phases U, V, and W of the motor power line. If the balance is off, there is a problem.

Replace the Servomotor.

Rotation direction is reversed.

The Servo Drive is set to the opposite rotation direction.

Jog the machine. If the rotation direction of the Servo Drive is opposite the jogging direction, the rotation direction of the Servo Drive is reversed. Also check for reversed feedback signals (phases A and B) and reverse rotation setting of the parameter.

Set the rotation direction of the Servo Drive correctly.

(During homing) The axis parameters that set the polarity of the home proximity sensor and the polarity of the home proximity input do not match.

Check the axis parameters and sensor polarity again.

Set the correct axis parameters.

(During homing) Incorrect wiring of the home proximity input

Check the axis input information in the Axis Variables to see if the home proximity input sensor turns ON/OFF.

Wire the home proximity input correctly.

3 Error Descriptions and Corrections

Problem Operation cannot be started, positioning is not completed, or positioning takes too much time to complete.
Abnormal noise
Motor shaft shakes.

Cause The in-position range of the Servo Drive is too narrow, and thus the current position does not enter the inposition range. (The current operation does not complete until the current position enters the in-position range, so you cannot start the next motion.) Servo Drive gain is low. The axis does not remain in the in-position range due to an external force.
Mechanical vibration
Insufficient adjustment of the Servo Drive gain (high gain) Incorrect Servomotor selection (adjustment not possible). Misalignment of the coupling that connects the motor shaft and machine Insufficient adjustment of the gain (low gain) Gain cannot be adjusted due to low machine rigidity.
Mechanical configuration prone to stick slip (highly sticky static friction) Incorrect Servomotor selection (adjustment not possible).

Item to check ---
--Check the axis input information for the Axis Variables to see if the difference between the command current position and the actual current position is within the in-position range. Check the moving parts of the machine for intrusion of foreign matter, damage, deformation, and loosening. ---
Select another motor (check the torque and inertia ratio).
---
---
In particular, this condition occurs on vertical axes, SCARA robots, palletizers, and other systems whose axes are subject to bending or tensional loads. ---
Select an appropriate motor (check the torque and inertia ratio).

Countermeasure Increase the in-position range.
Adjust the Servo Drive gain. If you stop the axis so that a position inside the inposition range is not achieved, such as holding control, you can use the following error reset output to forcibly achieve the inposition range. Correct the problem.
Perform auto-tuning. Manually lower the gain. Change to an optimal motor.
Adjust the motor and machine installation.
Perform auto-tuning. Manually increase the gain. Increase the machine rigidity. Readjust the gain.
Perform auto-tuning. Manually adjust the gain.
Change to an optimal motor.

Problem

Correction

Tag data is not concurrent.

Check the following items and correct the user program. · Data concurrency is maintained for each connection between the CPU
Unit and the built-in EtherNet/IP port. To maintain data concurrency for tag data links, set a refreshing task for the network variables that are assigned to tags. Refer to information on the Concurrency of Tag Data Link Data in the NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506) for details. · Refer to the product manuals for products from other manufacturers.

At startup, some of the receive · If the user program uses receive data, make sure that the All Tag Data

data is FALSE when it should be

Link Communications Status in communications status 1 or the Controller

TRUE.

Operating Mode for the target node is TRUE before you use the receive

data. To use operation information from the Controller, use Controller status in the tag sets on both the sending and receiving nodes.

· If the Fault Action setting of the output (produce) tag is enabled, The out-

put (produce) data changes to FALSE when a fatal error occurs in the

CPU Unit. Check the error status at the output (producing) Controller.

Tag data link communications are not stable.

· For an NX701 CPU Unit, use a 1,000 Mbps Ethernet switch if 10 or 100 Mbps is set or if you are using a 10 Mbps repeater hub, a 100 Mbps repeater hub, or a 1,000 Mbps repeater hub. The performance of the tag data links assumes that an Ethernet switch is used to achieve a 40,000 pps bandwidth for full-duplex, 1,000 Mbps auto-negotiation communications.
· For an NX102 CPU Unit, use a 100 Mbps Ethernet switch if 10 Mbps is set or if you are using a 10 Mbps or 100 Mbps repeater hub. The performance of the tag data links assumes that an Ethernet switch is used to achieve a 12000 pps bandwidth for full-duplex, 100 Mbps auto-negotiation communications.
· For an NJ-series CPU Unit and an NX1P2 CPU Unit, use a 100 Mbps Ethernet switch if 100 Mbps is set or if you are using a 10 Mbps or 100 Mbps repeater hub. For unit version 1.03 or later, the performance of the tag data links assumes that an Ethernet switch is used to achieve a 3,000 pps bandwidth for full-duplex, 100 Mbps auto-negotiation communications. For unit version 1.00 to 1.02, a 1,000 pps bandwidth is assumed.
· Refer to NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506) to access the error counters and discarded packed counters on the Ethernet Information Tab Page. Use the information to check for noise on the communications path, non-standard cables, damaged cables/connectors, unexpectedly high communications traffic, and incorrect loops in connections between Ethernet switches.
· Contact the Ethernet switch manufacturer if there are problems with the transfer capacity of the Ethernet switches in the communications path. If Ethernet switches are cascaded, the load may be concentrated on the middle Ethernet switches. Change the network configuration so that the load is not concentrated.
· Also, refer to NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (Cat. No. W506) and use the connection status on the Connections Tab Page to remove the cause of the error according to information in 15-3-2 Connection Status Codes and Troubleshooting.

· The Ethernet cable is broken. · The specified cable is not being
used.

The causes given on the left are possible if the error occurs from when the system starts operation or if it always occurs after a specific time after the system starts operation. Use the diagnostic and statistical information from the Sysmac Studio and check the EtherCAT communications status. If the Ethernet cable is broken or if the specified cable was not used, replace the cable. Or, reconnect the connector and make sure it is mated correctly.

· Confirm that the Ethernet cable
connector is mated securely.
· Make sure that the Ethernet ca-

according to the attached informa-

tion 1.

1) The EtherCAT master cannot start restore operation. (When the attached information 1 is 0002 hex)

The restore operation cannot be started due to the other event that is being occurred in the EtherCAT Function Module. Check the event that is being occurred, identify the error cause and make the correction.

Refer to the information on the event that occurred, implement preventive measures for the error cause, and then execute the restore operation.

2) The EtherCAT network configuration in the backup data does not agree with the physical network configuration. (When the attached information 1 is 0009 hex)

If any of the following events occur,
identify the error cause and make
the correction according to the in-
formation on the event that occur.
· Link OFF Error · Network Configuration Verifica-
tion Error (Slave Unconnected)
· Network Configuration Verifica-

· Illegal Slave Disconnection De-
tected
· Incorrect Wiring Detected · Ring Disconnection Detected

Make sure that the EtherCAT network configuration in the backup data agrees with the physical network configuration before you restore the data.

3) It was not possible to write the backup parameters to the EtherCAT slave. (When the attached information 1 is 0007 hex)

Ask the manufacturer of the slave if you can write all of the parameters that are set as backup parameters in the order displayed on the Backup Parameter Edit Pane for the slave. On the Backup Parameter Edit Pane, sort the parameters if they must be written in a certain order and delete any parameters that cannot be written.

5) Incorrect backup data was detected. (When the attached information 1 is 0008 hex)

a. Identify the error cause and make the correction according to the information on the event that occurred in the EtherCAT slave.
b. Check the number of error frames in the slave diagnostic and statistical information. Check whether the contact failure of the connector, connection failure of the cable, or noise occurred in the location where an error frame was counted and implement countermeasures.
Create the backup files again. If you fail to create the backup files again, format the SD Memory Card with the Sysmac Studio and then place the backup files on it.

a. Refer to the information on the event occurred, and implement preventive measures for the error cause.
b. Make sure that error frames are no longer counted in the diagnostic and statistical information for the master and slaves. If the error frame is counted, check whether the connection failure of the cable, contact failure of the connector, or noise occurred and implement countermeasures.
Do not remove the SD Memory Card or turn OFF the power supply while the SD BUSY indicator is lit. Or, replace the SD Memory Card periodically according to the write life of the SD Memory Card.

No. V117) · NS-series Programmable Terminals Programming Manual (Cat No. V073)

Precautions for Correct Use

On the NA-series HMI, operation related to the NX Bus Function Module is limited as follows.

Use the troubleshooting function of Sysmac Studio as necessary.

· Current errors in the NX bus master are displayed, but NX Bus Function Module is not dis-

played at Source. Current errors in NX Units mounted to the CPU Unit are not displayed.

· Resetting all errors is the only way to reset current errors.

· Event logs for the NX bus master are displayed, but NX Bus Function Module is not displayed

at Source. Event logs for NX Units mounted to the CPU Unit are not displayed.

· Event logs for the NX bus master can be deleted, but event logs for NX Units mounted to the

CPU Unit cannot be deleted.

Precautions for Correct Use
On the NS-series HMI, operation related to the NX Bus Function Module is limited as follows. Use the troubleshooting function of Sysmac Studio as necessary. · Current errors are not displayed. · Resetting all errors is the only way to reset current errors. · Event logs are not displayed. · Event logs for the NX bus master can be deleted, but event logs for NX Units mounted to the

A-6 Correspondence of Events between Project Unit Version Earlier than 1.40 and Project Unit Version 1.40 or Later

Events that occur in CPU Units are determined by the CPU unit versions, and they do not change
even if you change the project unit versions*1. *1. In this manual, the unit version set for a project is called "project unit version". A project unit version is set for
a project in the Select Device Area of Project Properties Dialog Box on the Sysmac Studio.

However, some events that occur in the EtherCAT Master Function Module differ between project unit version earlier than 1.40 and project unit version 1.40 or later. When you obtain the event code of an event that occurred by the host system and implement a processing, consider that the event code is different according to the setting of the project unit version and design the host system. The following table shows the correspondence of events between project unit version earlier than 1.40 and project unit version 1.40 or later.

A-7 Correspondence of NX Bus Events between NX102 CPU Units, NX1P2 CPU Units and Slave Terminals

The NX102 CPU Units, NX1P2 CPU Units and Slave Terminals support the mounting of NX Units. This means that NX102 CPU Units, NX1P2 CPU Units and Slave Terminals are subject to the same errors. However, with the NX102 CPU Units, NX1P2 CPU Unit, it is easier to identify the cause of an NX bus error because two or more events with more specific names may correspond to one Slave Terminal event. The table below shows the correspondence of NX bus events, where two or more NX102 CPU Unit and NX1P2 CPU Unit events correspond to one Slave Terminal event.
