Definitions and Symbols

A safety instruction (message) includes a "Safety Alert Symbol" and a signal word or phrase such as WARNING or CAUTION. Each signal word has the following meaning:

!HIGH VOLTAGE Indicates a potentially hazardous situation which, if not avoided, could result

in electric shock. It calls your attention to items or operations that could be dangerous to you and other persons operating this equipment.

Read the message and follow the instructions carefully.

!WARNING Indicates a potentially hazardous situation which, if not avoided, could result

in death or serious injury. Additionally, there may be severe property damage.

!Caution Indicates a potentially hazardous situation, which, if not avoided, may result in

minor or moderate injury, or property damage.

Step 1 Indicates a step in a series of action steps required to accomplish a goal. The

number of the step will be contained in the step symbol.

Note Notes indicate an area or subject of special merit, emphasizing either the

product's capability or common errors in operation or maintenance.

Tip Tips give a special instruction that can save time or provide other benefits

while installing or using the product. The tip calls attention to an idea that may not be obvious if you are a first-time user of the product.

1 Hazardous High Voltage

!HIGH VOLTAGE Motor control equipment and electronic controllers are connected to hazard-

ous line voltages. When servicing drives and electronic controllers, there may be exposed components with housing or protrusions at or above line potential. Extreme care should be taken to protect against shock.

Stand on an insulating pad and make it a habit to use only one hand when checking components. Always work with another person in case an emergency occurs. Disconnect power before checking controllers or performing maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electronic controllers or rotating machinery.

General Precautions - Read These First!

2 General Precautions - Read These First!

!WARNING Failure to read and understand the information provided in this manual may

result in personal injury or death, damage to the product, or product failure. Please read each section in its entirety and be sure you understand the information provided in the section and related sections before attempting any of the procedures or operations given.

!WARNING This equipment should be installed, adjusted, and serviced by qualified elec-

trical maintenance personnel familiar with the construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury.

!WARNING Wiring, maintenance or inspection must be performed by authorized person-

nel. Not doing so may result in electrical shock or fire.

!WARNING Hazard of electrical shock! Disconnect incoming power before working on the

OMRON 3G3AX-MX2-DRT-E DeviceNet Option Board or the MX2-A@ Inverter.

!HIGH VOLTAGE Turn the power supply OFF and wait for the time specified on the Option

Board front cover before performing wiring, maintenance or inspection. Not doing so may result in electrical shock.

The OMRON 3G3AX-MX2-DRT-E DeviceNet Option Board is attached to an MX2-A@ Inverter. Dangerous voltage exists until the MX2-A@ Inverter power light is OFF.

!HIGH VOLTAGE Do not touch the conductive parts such as the internal PCB, terminals or con-

nector while power is being supplied. Doing so may result in electrical shock.

!WARNING Do not attempt to take an Option Board apart or touch any internal parts while

the power is being supplied. Doing so may result in electric shock.

!WARNING Do not attempt to disassemble, repair, or modify an Option Board. Any

attempt to do so may result in malfunction, fire, or electric shock.

!WARNING Provide emergency stop circuits, interlock circuits, limit circuits and similar

safety measures in external circuits (NOT in the Option Board). This ensures safety in the system if an abnormality occurs due to malfunction of the Option Board or another external factor affecting the Option Board operation. Not doing so may result in serious accidents.

!WARNING Fail-safe measures must be taken by the customer 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.

!Caution Do not touch the Inverter during power on, and immediately after power off.

Hot surface may cause injury.

Installation Precautions

!Caution The product will be used to control an adjustable speed drive connected to

high voltage sources and rotating machinery that is inherently dangerous if not operated safely. Interlock all energy sources, hazardous locations, and guards in order to restrict the exposure of personnel to hazards. The adjustable speed drive may start the motor without warning. Signs on the equipment installation must be posted to this effect. A familiarity with auto-restart settings is a requirement when controlling adjustable speed drives. Failure of external or ancillary components may cause intermittent system operation, i.e., the system may start the motor without warning or may not stop on command. Improperly designed or improperly installed system interlocks and permissives may render a motor unable to start or stop on command.

3 Installation Precautions

!WARNING Always connect the grounding cable to one of the ground terminals of the

MX2-A@ Inverter. Failure to abide could lead to serious or possibly fatal injury.

!Caution Failure to observe these precautions could lead to faulty operation of the

Option Board or the Inverter, or could damage either of the two. Always read these precautions.

• Install external breakers and take other safety measures against short-circuits in external wiring. Not observing this may result in burning.

• Be sure that all cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.

• Do not allow metal clippings to enter either Option Board or Inverter when wiring or installing the unit.

• Follow the network configuration and wiring instructions provided in the DeviceNet Operation Manual (Cat. No. W267):

• Wire the DeviceNet cables and connectors correctly. Incorrect wiring may result in burning.

• Always connect a Terminating Resistor at the prescribed locations of the DeviceNet network to ensure the quality of the transmission path. Do not apply termination anywhere else.

• Be sure that the Option Board is mounted correctly. Improper mounting may result in malfunction.

• Disconnect the grounding cable when performing withstand-voltage tests. Not disconnecting the grounding cable may result in burning.

4 Configuration Precautions

!Caution Failure to observe these precautions could lead to unexpected operation of

the Option Board or the Inverter. Always read these precautions.

• Check the network related Inverter settings regarding DeviceNet node address and DeviceNet remote I/O allocation. Not doing so may result in unexpected operation.

• When replacing an Inverter be sure that all Inverter settings of the Inverter being replaced are restored to the replacement.

• Restoring parameters stored in the remote operator also restores the DeviceNet node address. Always check the node address and other network related Inverter settings after restore.

Getting Started

1-1 Introduction

1-1-1 Main Features

The 3G3AX-MX2-DRT-E allows controlling, monitoring and parameterization of an MX2-A@ Inverter via a DeviceNet network. The 3G3AX-MX2-DRT-E serves as a gateway that passes communicated register values from the DeviceNet network to the MX2-A@ Inverter and vice versa. The 3G3AX-MX2-DRT-E adheres to the DeviceNet / CIP AC Drive profile.

The following functions are available via DeviceNet communication by installing the 3G3AX-MX2-DRT-E:

Cyclic Data Exchange The DeviceNet Master and 3G3AX-MX2-DRT-E can exchange data via a

DeviceNet Remote I/O connection:

• Output data (from DeviceNet Master to 3G3AX-MX2-DRT-E): E.g. Run/stop, Reference frequency and Fault reset.

• Input data (from 3G3AX-MX2-DRT-E to DeviceNet Master): E.g. Inverter status, Output frequency and Output current, etc.

Inverter Parameter Access The DeviceNet Master can read and write parameter data via the

3G3AX-MX2-DRT-E using the explicit message communication.

The inverter parameters are accessible in multiple ways:

• Access based on Function code

• Access based on the Modbus register address

Several AC Drive profile attributes can also be accessed using the explicit message mechanism.

Simplified Start-up The 3G3AX-MX2-DRT-E can be set up easily, just by wiring the Unit, setting

the DeviceNet node address (P192) and the default connection path (P046) and restarting the unit. The Unit’s configuration is read automatically when the power is turned ON or after a reset. It is not necessary to make any settings with a special Programming Device.

Simplified Replacement All parameters required by the 3G3AX-MX2-DRT-E are stored in the MX2-A@

Inverter. The 3G3AX-MX2-DRT-E can be replaced, requiring no re-configuration.

Automatic Baud Rate Recognition

Note If the DeviceNet Master Unit’s baud rate changes, reset the Master Unit and

The 3G3AX-MX2-DRT-E automatically detects the Master’s communication baud rate, and no user configuration is required.

be sure to turn OFF and ON or reset the 3G3AX-MX2-DRT-E and other connected Slave Units to detect the new baud rate.

1-3 Introduction to DeviceNet

1-3-1 Overview of DeviceNet

DeviceNet is a multi-bit, multi-vendor network that combines control and monitoring on a machine/line-control level and that conforms to DeviceNet open field network specifications. DeviceNet is a member of a family of networks that implements the Common Industrial Protocol (CIP) at its upper layers.

Two types of communications are supported to provide a single point of connection for both control and configuration:

1. Time-critical control remote I/O communications that automatically transfer between the Master Unit/CPU Unit and the remote Slave Units, and

2. Explicit message communications that read/write messages, control operation, or perform other functions to the Slave Units. Message communications are achieved by executing specific instructions from the program in the CPU Unit to which the Master Unit is mounted.

Page 19

Introduction to DeviceNet Section 1-3

1-3-2 What is the AC Drive profile

Within DeviceNet/CIP standard, multiple device profiles have been defined. Therefore the devices which adhere to a certain device profile are compatible and replaceable in a multi-vendor environment.

The AC Drive device profile (profile code 0x02) supplements the DeviceNet/ CIP standard. It defines a unified behaviour and technique to access Inverter and drive device data. All drives supporting the AC Drive profile respond the same way to control instructions.

cific events (start-up, PLC program mode, etc). In this case, consider to put Action to Network Idle Mode (P048) to value 2 (no action).

!Caution Check the network related Inverter settings regarding DeviceNet node

address and other settings. Not doing so may result in unexpected operation.

The EDS file contains the access data for most of the Inverter’s parameters. This enables DeviceNet configurators such as CX-Integrator to configure the Inverter.

The defaults of the parameters have been selected specifically for the Option Board and not necessarily the same as the Inverter parameter's default value.

Please note that the write access of the Inverter parameters may depend on the Inverter mode. Also make sure the Inverter is not in trip state before downloading the parameters.

!WARNING During the parameter initialisation (Inverter parameter b180), operating the

Inverter is not prevented automatically and doing so may lead to unpredicted behaviour. Be sure to not operate the Inverter and do not write any Inverter parameter during the parameter initialisation by Option Board or any other interface.

3-3 Configuring the Network

The slaves will be allocated data in the I/O Memory of the Master Unit or CPU Unit the Master Unit is mounted to. They are allocated using one of the following methods:

1. Fixed allocations

2. User-set allocations

For details about configuring the OMRON CJ1W-DRM21 and CS1W-DRM21 Master Unit’s using CX-Integrator as configurator software, refer to DeviceNet Unit Operation Manual (Cat. No. W380).

Fixed Allocation Steps

Step 1 Turn ON the communications, inverter(s), and Master Unit or PLC power sup-

plies.

Step 2 Confirm the Option Board’s node number (inverter parameter P192) and

Default Connection Path (inverter parameter P046) are set properly. See explanation in previous section.

Step 3 Perform the Fixed allocation sequence as defined for the Master Unit.

Step 4 Once the network is re-started with the new settings, check that the Option

Board LED indicators indicate proper operation: If everything is correctly configured, both the MS (Module Status) LED and the NS (Network Status) LED

will be Green. Please refer to section 5-1 Troubleshooting Using the LED Indi- cators for troubleshooting any configuration errors if the LED indicators are

displaying a different pattern.

Tip In case of any errors during configuring the network, please refer to SECTION

5 Troubleshooting and Maintenance.

Page 33

Configuring the Network Section 3-3

For the fixed allocations, the configuration can be done without the DeviceNet configurator. The output and input data of the slaves are allocated strictly in order of node address in the areas. The Master Unit will check the Default connection path of the actual Slave to select which assemblies will be used for the configuration.

User-set Allocation Steps The following steps are based on configuration of the OMRON CJ1W-DRM21

Master Unit using CX-Integrator tool.

Step 1 Connect CX-Integrator to the network through a serial line or other interface.

Step 2 Turn ON the communications, inverter(s), and Master Unit or PLC power sup-

plies.

Step 3 Open the Configurator and perform the User-set allocation sequence as

defined for the Master Unit.

Step 4 Create network topology by either

• offline operation adding Master Unit and Slaves or

• uploading connected network.

Be sure to match the project’s Slave node numbers with the actual numbers of the Unit’s (as set with inverter parameter P192).

Step 5 In the Master Unit’s Edit Device Parameter window (General tab), register the

Device List for the connected Devices.

Step 6 Use the Advanced setting for the Slave to select the connection and assem-

blies required. See note.

Step 7 Go to the I/O allocation (IN/OUT) tabs to allocate the IO assemblies of the

Slaves to PLC memory.

Step 8 Save and download the configuration to your DeviceNet Master Unit.

Step 9 Once the network is re-started with the new settings, check that the Option

Board LED indicators indicate proper operation: If everything is correctly configured, both the MS (Module Status) LED and the NS (Network Status) LED

will be Green. Please refer to section 5-1 Troubleshooting Using the LED Indi- cators for troubleshooting any configuration errors if the LED indicators are

displaying a different pattern.

Page 34

Configuring the Network Section 3-3

Note 1 For a particular connection type (Poll, COS, Cyclic), only one of the pre-

defined pairs as listed for the Default Connection Path (P046) can be configured. Please note in case a non-matching pair is selected, no error is generated. For either the input or output assembly, the matching pair will be configured.

Note 2 Third party masters may require to set the inverter parameter P046 Default

Connection Path corresponding to the User-set selection.

Note 3 When using only COS or Cyclic connection, be sure to put the Network Error

Timer P044 in the Inverter higher than the COS/Cyclic Heart beat timer.

Tip In case of any errors during configuring the network, please refer to SECTION

5 Troubleshooting and Maintenance.

For the user-set allocation, the DeviceNet configurator is used. The output and input data assemblies of the slaves can be allocated freely to the Master Units IO blocks. Also specific connection variants (Poll, Bit-Strobe, COS, Cyclic) can be selected based on the settings in the EDS file.

4-1 Setting up inverter

Unless otherwise specified, all usage examples make use of the Extended

Speed IO format as the default connection path (Refer to section 3-1 Installa- tion of EDS files, Step 2). Prepare the Inverter and Option Board before start-

ing with the usage examples:

Step 1 Initialize the Inverter mode to Std. IM by first setting b171 = 1 and then

b180 = 1 (Refer to MX2 User’s manual (Cat. No. I570) section 3-6-24).

Step 2 Set the Inverter rating to CT (constant torque) by setting b049 = 0 (Refer to

the MX2 User’s manual section 3-2-5).

Step 3 Configure the Option Board and Network as explained in sections 3-1 Installa-

tion of EDS files and 3-2 Configuring the Option Board with Extended Speed

IO (Output assembly 21, Input assembly 71). There are two options:

• When using Fixed allocation method of configuring the master, select P046 = 1.

• When using User-set allocation, select the two Extended Speed IO assemblies.

If you configured everything correctly, your output and input I/O words should contain the following data:

SECTION 4

Operations and Monitoring

!Caution Check the Inverter settings for proper Inverter behaviour before actually oper-

ating the Inverter remotely via the network.

Page 36

Operating the Motor Section 4-2

The product will be used to control an adjustable speed drive connected to high voltage sources and rotating machinery that is inherently dangerous if not operated safely. Interlock all energy sources, hazardous locations, and guards in order to restrict the exposure of personnel to hazards. The adjustable speed drive may start the motor without warning. Signs on the equipment installation must be posted to this effect. A familiarity with auto-restart settings is a requirement when controlling adjustable speed drives. Failure of external or ancillary components may cause intermittent system operation, i.e., the system may start the motor without warning or may not stop on command. Improperly designed or improperly installed system interlocks and permissions may render a motor unable to start or stop on command.

4-2 Operating the Motor

4-2-1 Starting the Motor

Step 1 Set A001 = 4 and A002 = 4 so that the Inverter can be controlled using the

DeviceNet Option Board.

Note The net control (CTR) and net reference (REF) override bits in the 1

word can be used to override A001 and A002. When these bits are set, it has the same effect as temporarily setting A001 = 4 and A002 = 4. Clearing these bits removes the override, and the Inverter sources are once again determined by these registers. Please note in case the inverter has version AAAA, override is not supported for A002 = 2.

Step 2 Set F002 and F003 for adjusting the acceleration and deceleration time of the

motor. Refer to MX2 User’s manual (Cat. No. I570) section B-4.

Step 3 Set the Rotation Speed Reference (see Appendix B) of the Inverter in the 2

I/O output word to 10.00 Hz.

Step 4 Set the FWD bit to put the Inverter in run mode. The RUN indicator on the

Inverter should light up at this point. If this is not the case, check your source selection (please refer to section 3-2 step 5).

The motor accelerates until it reaches the desired frequency. Notice that the ARF bit is set once the inverter has reached the desired Rotation Speed Reference.

4-2-2 Changing Direction

Step 5 Clear the FWD bit and set the REV bit.

output

The motor decelerates stops and then accelerates in the opposite direction. ARF bit clears as soon as the Rotation Speed Reference is changed. Once the new Rotation Speed Reference is reached, ARF bit is set again.

4-2-3 Stopping the Motor – Decelerated stop

Step 6 Clear the run bits (FWD or REV) to bring the motor to a controlled (deceler-

ated) stop.

The motor decelerates, and comes to a stop. ARF bit clears as soon as the run bit is cleared.

Before continuing set Rotation Speed Reference to 0 Hz.

Note The motor can also be brought to a stop by setting Rotation Speed Reference

to 0 Hz and leaving the run bits set. The Inverter will however stay in run mode once the motor has reached 0 Hz.

Page 37

Overriding Inverter inputs Section 4-3

4-2-4 Stopping the Motor – Free-running

An alternative to Clear the run bits (FWD or REV) to bring the motor to a controlled (decelerated) stop of step 6 is a free-run stop. The Inverter stops controlling the motor, and the motor coasts to a stop. Set C001 = 11 (FRS: freerun stop) to assign intelligent input terminal 1 as free-run stop enable. Restart the Inverter or reset the Option Board for the new settings to take effect. Set the terminal input 1 to ON to enable free-run stop. During a free-run stop, Rotation Speed Monitor immediately drops to 0 and ARF bit is cleared.

4-2-5 Changing Speed Reference and Speed Monitor Scaling

Rotational Speed Reference and Rotational Speed Monitor are word registers. The scaling of these values depend on the inverter's Motor poles setting P049:

1. In case P049 has non-zero value, the Unit is RPM.

2. In case P049 is set to zero, the Unit depends on the inverter mode. If the inverter is in High Frequency (HF) mode, the Unit is 0.1 Hz. The unit will be

0.01 Hz in other modes.

For the second option (Unit is either 0.1 Hz or 0.01 Hz), the maximum frequency which can be set is 400.00 Hz. Please refer to MX2 User's manual (Cat. No. I570) for instructions about inverter modes and parameter P049.

4-3 Overriding Inverter inputs

By using the Option Boards input override functionality, the Inverter Intelligent Terminal Functions can be controlled from the network.

The following example explains how to make use of the Option Board to override the input function Free Run Stop (FRS) using the IO data.

Step 1 Configure the Option Board and Network as explained in sections 3-1 Installa-

tion of EDS files on page 15 and 3-2 Configuring the Option Board on page 15

with Extended Control IO and Multi-function IO monitor (Output assembly 101, Input assembly 151). There are two options:

• When using Fixed allocation method of configuring the Master, select P046 = 4.

• When using User-set allocation, select the Extended Control IO and Multifunction IO monitor assemblies.

Step 2 Set C003 = 11 (FRS: Free Run Stop) to assign intelligent input terminal 3.

Step 3 The output words of assembly 101 contain the CI3 bit (see table 16), which

overrides input terminal 3. Set this bit to enable the free run stop.

Please note that as an alternative to override inputs using this assembly with bits CI3 to CI7, also the explicit message writing the Discrete Input Point

Object (0x08) can be used. Please refer to APPENDIX B Assembly Specifica- tion on page 43 and APPENDIX E DeviceNet Explicit Messages on page 71).

4-4 Controlling Inverter Torque

In addition to Speed control, the MX2-A@ Inverter allows direct control of the motor torque.

!Caution Before following this example, disconnect your motor from any load to prevent

injury or damage to property.

The following example explains how to make use of the Option Board to control the motor torque:

Multi function IO monitor (Output assembly 101, Input assembly 151). There are two options:

• When using Fixed allocation method of configuring the master, select P046 = 4.

• When using User-set allocation, select the two Extended Control IO and Multi-function IO monitor assemblies.

Step 2 Set C003 = 52 (ATR: permission of torque command input) to assign intelli-

gent input terminal 3 as torque enable. See also section 4-3 Overriding

Inverter inputs

Step 3 Set parameter A044=3 to enable Sensorless Vector Control (SLV).

Step 4 Set parameter P033=6 to assign Torque command input selection to Option

Board.

Step 5 Restart the Inverter or reset the Option Board for the new settings to take

effect.

Note The Inverter will only allow setting of torque related registers if it is configured

to operate with CT rating in Std. IM mode.

Your input and output process areas should now have the following layout:

Step 6 Set the maximum allowable output frequency in torque mode by configuring

P039 and P040 for the forward- and reverse run directions. Be careful to select safe limits for your test setup.

Page 39

Faults and Trips Section 4-5

Step 7 Set the Rotation Speed Reference (see APPENDIX B Assembly Specification

on page 43) of the Inverter in the 2

I/O output word to 10.00 Hz.

Step 8 Set the Torque Reference of the Inverter in the 3

Step 9 Set the FWD bit to put the Inverter in run mode. The motor will accelerate to a

constant forward output frequency.

Step 10 Override the input terminal 3 (CI3) to enable torque command input.

The motor either accelerates or decelerates depending on the load. The output frequency is limited by the P039 setting. The output torque is given by d012.

Step 11 To change the torque command direction, clear the FWD bit and set the REV

bit.

The motor decelerates and accelerates in the opposite direction. The output frequency is limited by the P040 setting.

Note As an alternative for the overriding of input terminal 3 from the network at step

10, also the physical input terminal can be used.

4-5 Faults and Trips

4-5-1 External Trip

You may want to trip the Inverter from your PLC program. Not all assemblies support setting the external trip by using a bit in IO Data. Basically there are two options:

• Select an assembly which support this trip set in the output data.

• Using explicit message to set the Force Fault/Trip attribute in the Control

Step 12 Clear the Opr bit to stop the motor. The motor decelerates and comes to a

halt.

4-7-3 Faults and Trips

User trips can be generated by setting the EXT bit in coil data 0. You must always immediately clear the Opr bit in your PLC program when the Unit indicates it is in Trip status (for example when AL bit is set ON). If the Opr bit is set when the trip condition is cleared, the Inverter will immediately start running!

!WARNING Always clear the Opr bit in your PLC program when the AL bit is set ON by the

Inverter. Not doing so may result in the motor starting unexpectedly when the trip is cleared.

Set and clear the RS bit in coil data 0 to clear a trip.

!WARNING Always clear the RS bit after setting it. Not doing so will result in new trip con-

ditions automatically being cleared.

4-9 Monitoring additional Inverter status using COS

Typically the default DeviceNet Poll connection is used for controlling and monitoring the main functions of the Inverter. For specific monitoring of Inverter states, a second connection Change of State (COS) can be added. We will use the Flexible format for this connection.

The following steps are based on configuration of the OMRON CJ1W-DRM21 Master Unit using CX-Integrator tool. The configuration must be done using the user-set allocation method.

Step 1 Configure the Option Board and Network as explained in sections 3-1 Installa-

tion of EDS files and 3-2 Configuring the Option Board. Use the Advanced

Setting for the Slave to select both the Poll connection as the specific COS connections.

Note 1 The output assembly of the COS connection is the same as for the Poll con-

nection, in this case assembly 21 Extended Speed Control.

Note 2 The default length of the 159 Flexible input is 20 bytes, you can change this as

explained in the next step.

Page 45

Monitoring additional Inverter status using COS Section 4-9

Step 2 To change the specific size of the assembly, select the I/O Allocation Tab and

modify the size in the Edit I/O Allocate window according the input data size.

Step 3 Set the Flexible format parameter P170 to P179 to the Modbus address

required. For example:

Table 23 COS Parameters

Parameter Allocated Modbus register Value

P170 Trip cause of current Inverter trip 0012 Hex

P171 d002: Output current monitor 1003 Hex

P172 d012: Torque monitor 1010 Hex

P173 d013: Output voltage monitor 1011 Hex

Note the other parameters P160 to P169 and P174 to P179 are zero.

Step 4 Download the configuration to the Master Unit and also restart the Inverter to

apply the new values of the parameters.

The resulting configuration will have additional monitoring of inverter status specifically to the application’s requirements. Please note that for the COS also Bit-Strobe can be used as an alternative.

5-1 Troubleshooting Using the LED Indicators

The two bi-color LED indicators on the Option Board provide information on the Option Board mode and status and the network status.

When an error occurs, the Option Board trips the Inverter so that an error code is displayed on the fourdigit display of the Inverter. Use the error code to help troubleshoot the error.

In the following sections typical LED indicator and four-digit Inverter display patterns are provided to assist in troubleshooting. To show the status of the indicators, the following conventions are used:

Tip Do not clear the trip before you are finished troubleshooting an error. When

you clear the trip, the error code is cleared from the four-digit display. You may therefore lose the error information before you are able to start troubleshooting. Checking data in trip history is still an option in this case.

5-1-1 Option Board or Inverter Errors

During the Initialization process the MS and NS indicator shortly blink GREEN and RED to show correct operation of the indicator. Once the initialization has been completed correctly, the MS indicator will lit GREEN.and the NS indicator will be OFF.

One of the configuration parameters P160 – P179 has been rejected by the Inverter.

Your Inverter settings are not compatible with this version of the 3G3AX-MX2-DRTE.

Possible Cause(s) Corrective Action

Check (and correct) the following items: STEP I:

• Is one of the parameters P160 – P179 specifying a Modbus register that does not exist?

• If one of the parameters P160 – P169 is specifying a doubleword Modbus register: Are both the low- and high-words specified in sequence by two consecutive parameters?

• If one of the parameters P170 – P179 is specifying a doubleword Modbus register: Are both the high- and low-words specified in sequence by two consecutive parameters?

• Is a specific Modbus register specified twice in the output parameter registers P160 – P169?

• Is one of the output parameters P160 – P169 specifying a Modbus register that is read only? (A register is read-only if it has an ‘R’ in the ‘R/W’ column in section B-4-2 of the MX2 User’s manual (Cat. No. I570).)

• Is one of the output parameters P160 – P169 specifying a Modbus register of which the parameter is not run-mode editable? (A parameter is not run-mode editable if it has an ‘’ in the ‘Run Mode Edit’ column in section 3 of the MX2 User’s manual.)

STEP II: Restart the system by one of the following method

• Power OFF and ON

• Press the stop button on the Operator panel.

• Use the RS function of the intelligent input terminal.

Recovery via the fieldbus:

• Use Modbus Class Object to set the Trip reset coil (04h) in coil register 0x1F01.

• Check P046 value in range [0..7] and restart unit.

• Reset the Inverter to factory defaults. If the problem persists, contact your local OMRON representative for assistance.

Network power failure. Check (and correct) the following items:

Critical link failure. The Option Board detects too many communication errors. (CAN bus off.)

Connection time-out. The Option Board detects communication lost.

Possible Cause(s) Corrective Action

Check (and correct) the following items: Is the DeviceNet master sending IDLE messages? Check P048

to select the Action on Network Idle. Increase the value of P044, the timeout value. (COS/Cyclic

connections require the P044 time-out to be set to a value larger than the heart-beat timer).

Are the correct pins wired on the DeviceNet connector? Are there any short circuits or line interruptions? Is the correct power supplied (between 11 and 25V)?

Check (and correct) the following items: Are the correct pins wired on the DeviceNet connector? Are there any short circuits or line interruptions? Is the ground cable of the option board connected with a

ground terminal of the MX2 Inverter? Are the MX2 installation guidelines to comply with EMC recom-

mendations properly implemented (refer to MX2 User’s manual (Cat. No. I570) section D-1)?

Are you using the correct cable type? If you have branches from the DeviceNet cable main line: Are

any of these branches too long? Are the terminators mounted on both ends of the trunk only? Is noise interference excessive?

Check (and correct) the following items: Are the correct pins wired on the DeviceNet connector? Are there any short circuits or line interruptions?

5-1-4 Commisioning Mode

When using one of the OMRON tools during commissioning time, the 3G3AX-MX2-DRT-E can be set into commissioning mode. A clear indication will be given by the tool.

Commissioning mode is NOT an error, but it can influence normal system operation. During commissioning mode, Inverter parameter access takes priority over cyclic data exchange. Accessing Inverter parameters will therefore delay cyclic data exchange causing unexpected latencies.

!Caution Make sure that commissioning mode is disabled before operating the system.

Glossary

Bit Strobe In case a Slave unit is configured for bit strobe data exchange, it will send data

immediately when it has received a broadcast request (Input only).

Bus off A bus off condition occurs when an large ragte of errors is detected on the

CAN bus by the device. The device can no longer receive or transmit messages on the network. This condition is often caused by noise on the network or incorrect data rate setting.

Change of state (COS) In case a Slave unit is configured for change of state data exchange, it will

send data immediately when its data has changed. This mechanism reduces the network traffic as unchanged data does not need to be transmitted.

The mechanism does have a maximum time interval after which unchanged data will be transferred.

Cyclic I/O In case a Slave unit is configured for cyclic I/O data exchange, it will send data

at a fixed user-configurable time interval.

Flexible Format

The Flexible Format implements I/O data exchange that supports direct mapping of MX2-A@ Inverter Modbus registers in the I/O area. The Flexible Format provides

1. User configurable allocation of the IO Data to any Modbus register

2. Flexibility to set the size of the IO data to only transfer the necessary data, minimising fieldbus traffic.

This offers fieldbus- and profile-independent control of the MX2-A@ Inverter.

The exchanged registers are configured by setting Inverter registers P160 – P179 to the appropriate Inverter Modbus addresses.

Note The MX2-A@ Inverter places some restrictions on the Modbus register selec-

tion.

• For a Modbus Register to be mapped for output data exchange, it must be both run-mode editable and writable.

•MX2-A@ Inverter parameters may not be accessible depending on the Inverter’s mode (High frequency mode, Permanent magnet mode, Torque mode, etc).

Flexible I/O Mapping

Tip Refer to section B-4-2 of the MX2 User’s manual

Tip Refer to section 3-2-3 of the MX2 User’s manual

Tip The MX2-A@ Inverter parameter B031 (Sofware Lock Mode) determines the

various protection levels. Be sure to set the appropriate value B031 = 10 to be able to set parameter during run-mode.

Tip When using Flexible Format, the Inverter is controlled via Modbus registers.

Set A001/A201 = 3 and A002/A202 = 3 to make use of the Modbus control registers for typical Flexible Format use.

Content

Flexible I/O Settings Please consider the following notes when setting the parameters P160 to

P179.

Note 1 The parameters P160 to P179 determine the size of the input and output data.

The IO size is determined by the highest non-zero parameter. For example for output: if P164 is the highest non-zero parameter, the output data size will be

Page 94

APPENDIX F

5 words. Both output as input size should have a minimum size of 1 word.

Note 2 Setting specific parameters in the range to 0 (not at the end), can be used to

reserve IO memory. If set to 0 (zero), an output register is ignored and a 0 (zero) is mapped into an input register.

Note 3 Double-word MX2 registers should be mapped with two modbus registers in

sequence: high-word following low-word. Mapping only the low word in output data will write zero in the high word of the MX2 register. Mapping only the low word in input data is not allowed.

Note 4 It is not allowed to map the same register more than once in the output area.

Note 5 An incorrect setting of P160 to 179 will lead to a Major Recoverable Fault (MS

blinking Red) and inverter trip state E64. In such case, correct the parameter

values and restart (or reset, see APPENDIX E DeviceNet Explicit Messages)

the Unit.

Tip In case the trip state E64 is generated, multiple incorrect settings in range

P160 - 179 can have caused this error. If the error persists after some changes: it would be convenient to start with a small configuration which is correct and add a new register one by one (checking by restarting the Unit).

Tip Set the following register values:

• P160 = 1F01h: This gives you control over Modbus Coils 0000h through 000Fh using the first output word. These coils implement all the important control functions of the MX2-A@ Inverter.

• P161 = 0001h and P162 = 0002h: This gives you control over the frequency reference using output words 2 and 3.

• P170 = 1E01h: This allows you to monitor Modbus Coils 0010h through 001Fh as the first input word. These coils implement the most important status information of the MX2-A@ Inverter.

• P171 = 1001h and P172 = 1002h: This allows you to monitor the output frequency using input words 2 and 3.

The Modbus coil definitions for the MX2-A@ Inverter are listed in section B-41 of the MX2 User's manual (Cat. No. I570).

In case the output data is required to be as small as possilbe, please consider to only use register 0002h (instead of both 0001h and 0002h) as frequency reference. The resulting configuration is P160 = 1F01h and P161 = 0002h.
