Keep this manual handy for quick reference.

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.

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.

Page 10

General Precautions - Read These First!

!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

Option Board or the 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 Option Board is attached to an Inverter.

Dangerous voltage exists until the 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.

!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.

Installation Precautions

3 Installation Precautions

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

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 "PROFIBUS Installation Guideline for Cabling and Assembly" (PNO Order No. 8.022)

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

• Apply termination at both ends of a PROFIBUS cable segment. 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 PROFIBUS node address and PROFIBUS map selection. 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 PROFIBUS node address. Always check the node address and other network related Inverter settings after restore.

5 Application Precautions

!WARNING Before using the product under conditions which are not described in the

manual or applying the product to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative.

!WARNING It is extremely important that the Unit is used for its specified purpose and

Application Precautions

!WARNING Failure to observe these precautions could lead to serious or possibly fatal

injury. Always read these precautions.

• Check any user program in the system that acts as a PROFIBUS master before actually running it. Not checking the program may result in unexpected operation.

• A revision AAAA Inverter allows the motor to run immediately if a trip condition is reset, and at the same time, a run command is active via PROFIBUS. For safe operation clear the run command via PROFIBUS as soon

as a trip condition is detected. Refer to section 1-1-2 Inverter Suppor t to

determine the Inverter revision.

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

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

• Check the Inverter settings for proper Inverter behavior before actually operating the Inverter remotely via the PROFIBUS network.

• Check the Inverter's EzSQ program and its interaction with the PROFIBUS master before actually running it on the Inverter. Not checking the program may result in unexpected operation.

• Confirm that no adverse effect will occur at the moment the PROFIBUS master stops communicating with the Inverter or at the moment the PROFIBUS master has not yet started communicating to the Inverter.

• Confirm that no adverse effect will occur in the Inverter before force-setting/force-resetting any bit in the system that acts as a PROFIBUS master.

Getting Started

1-1 Introduction

1-1-1 Main Features

The Option Board 3G3AX-MX2-PRT-E and the 3G3AX-RX-PRT-E allow controlling, monitoring and parameterization of an Inverter via a PROFIBUS network.

The Option Board serves as a gateway that passes communicated register values from the PROFIBUS network to the Inverter and vice versa.

The following functions are available via PROFIBUS communication by installing the Option Board:

Cyclic Data Exchange The PROFIBUS Master and Option Board can exchange data via a PROFI-

BUS DP-V0 message connection:

• Output data (from PROFIBUS Master to Option Board): E.g. Run/stop, Reference frequency and Fault reset

• Input data (from Option Board to PROFIBUS Master): E.g. Inverter status, Output frequency and Output current

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

Option Board using the mailboxes provided by some modules, as well as a PROFIdrive DP-V1 parameter channel.

Simplified Start-up The Option Board can be set up easily, just by wiring the Unit, setting the

PROFIBUS node address (P180) and device profile (P182) and restarting the unit. The Unit's configuration is read automatically when the power is turned ON. It is not necessary to make any settings with a special Programming Device.

Simplified Replacement All parameters required by the Option Board are stored in the Inverter. The

Option Board can be replaced, requiring no re-configuration.

Automatic Baud Rate Recognition

The Option Board automatically detects the Master's communication baud rate, and no user configuration is required.

Note The PROFIdrive DP-V1 parameter channel is only available if the PROFIBUS

Master also provides DP-V1 Class 2 (MSAC2) Messaging to the user.

Note If the PROFIBUS Master's baud rate changes, the PROFIBUS Communica-

tion Unit must be turned OFF and then ON to detect the new baud rate.

Introduction to PROFIBUS Section 1-3

1-3 Introduction to PROFIBUS

1-3-1 The Purpose of PROFIBUS

PROFIBUS (PROcess FIeldBUS) is an open fieldbus standard for a wide range of applications in manufacturing, processing and building automation. The Standard, IEC 61158 (Industrial communication networks), to which PROFIBUS adheres, guarantees vendor independence and transparency of operation. It enables devices of various manufacturers to intercommunicate without having to make any special interface adaptations.

1-3-2 What is PROFIBUS DP

PROFIBUS DP (for Decentralized Periphery) is a variant optimized for high speed and low-cost interfacing. It is specially designed for communication between automation control systems and distributed I/O at the device level.

PROFIBUS DP uses the same transmission technology and uniform bus access protocol as PROFIBUS FMS (for Fieldbus Message Specification). Consequently, both versions can be operated simultaneously on the same bus. DP field devices, however, cannot be controlled by FMS masters and vice versa.

!Caution It is not possible to exchange a PROFIBUS DP device or master for a PROFI-

BUS FMS device or master. This will cause faulty operation.

1-3-3 What is PROFIdrive

The PROFIdrive device profile supplements the PROFIBUS standard. It defines a unified behavior and technique to access Inverter and drive device data. All drives supporting the PROFIdrive profile respond the same way to control instructions.

!Caution For backward compatibility and direct use of the Inverter registers, the Option

Board offers two additional device profiles that are NOT PROFIdrive compliant. For PROFIdrive compliance, ensure that P182 = 0.

Configuring Drive Parameters and Option Board

3-1 Configuring the Option Board

All Option Board parameters are stored in the Inverter. This allows for easy replacement of the Option Board without the need to re-configure. After connecting the Option Board to an Inverter for the first time however, proceed with the following steps:

Step 1 The Option Board supports 3 device profiles. Each device profile supports a

subset of the modules listed in the GSD file. The device profile is selected using Inverter parameter P182. Use the Inverter keypad to adjust P182 to select the device profile and supported modules.

Step 2 It is recommended to set C102 = 3 to prevent the Inverter reset input and

Stop/reset button from interfering with Option Board during operation (Setting C102 to another value causes the Option Board to reset when a trip condition is cleared). Use the Inverter keypad to set C102 to 3.

Step 3 Inverter registers P180, P044, P045 and P181 configure the PROFIBUS net-

work-related parameters. Adjust these to configure the node address, CLEAR mode behavior and required action when a Fieldbus failure occurs.

Step 6 The PPO modules and Flexible module give you the freedom to select/cus-

tomise the Inverter Modbus registers for Cyclic Data Exchange. Inverter registers P160 - P179 are used to configure and map the exchanged Modbus registers. If required, adjust these registers to change the default content of

the exchanged data. Please refer to Appendices B-1 I/O Mapping on page 76 and Flexible I/O Mapping on page 83 for more details.

Configuring the Network Section 3-2

Step 7 Restart the Inverter for the changes to take effect.

Note When restarting the Inverter, wait for the Inverter power indicator to go out

before switching on again.

!Caution Action on Network Error (P045) is disabled when P181 is set to 1 (Keep the

output data upon a network failure) I.e. when a network error occurs, the Inverter will continue normal operation with the last received output data.

!Caution Check the network related Inverter settings regarding PROFIBUS node

address and PROFIBUS map selection. Not doing so may result in unexpected operation.

Tip Alternatively, P180 in Step 3 may be performed using the set-slave address

functionality of your PROFIBUS master or diagnostic tool.

Tip Alternatively, Step 2 up to Step 6 may be performed using OMRON CX-Drive.

Tip Alternatively, Step 7 may be performed by resetting the Option Board using

PNU972 (Refer to APPENDIX F Option Board Parameters).

3-2 Configuring the Network

Step 1 Download the GSD file named OC_0C6A for the Option Board via the Omron

website http://industrial.omron.eu.

Download the GSD file named OC_0D2B for the Option Board via the Omron website http://industrial.omron.eu.

Step 2 Install / add this GSD file to the PROFIBUS master configuration program

used to configure your PROFIBUS master. (It may be necessary to update the device catalogue before proceeding)

Step 3 Add your PROFIBUS master to the network in the configuration program.

Step 4 Add an Option Board to the network in the configuration program and open

the Option Board's settings.

Step 5 Set the Option Board's node address (also referred to as station address) to

match P180 in the Inverter.

Step 6 Choose a module that is supported by the selected device profile (Inverter

parameter P182).

Step 7 Uncheck the Enable DPV1 option on the DPV1 tab before proceeding to Step

7 if you are using OMRON CX-Configurator.

Step 8 Save and download the configuration to your PROFIBUS master.

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, only the RUN and COMM indicators will be ON (green). Please refer

to section 5-1 Troubleshooting using the LED indicators on page 57 to trouble-

shooting any configuration errors if the LED indicators are displaying a different pattern.

Note Nothing prevents you from selecting an unsupported module in Step 6. If you

are uncertain, check the value of P182 before selecting the module.

SECTION 4

Operations and Monitoring

This section provides some common usage examples to help you get started. Unless otherwise specified, all usage examples make use of the PROFIdrive

device profile and associated modules (Refer to section 3-1 Configuring the Option Board, Step 1). Prepare the Inverter and Option Board before starting

with the usage examples:

Step 1 Initialize the Inverter mode to Induction Motor, Constant Torque:

Set b171 = 1 and then b180 = 1, set b049 = 0.

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

Set b084 = 2 and then b180 = 1, set b049 = 0.

Refer to RX User’s manual (Cat. No. I560) section 4-2 Parameter Initialization).

Step 2 Configure the Option Board and Network as explained in sections 3-1 Config-

uring the Option Board and 3-2 Configuring the Network, but limit the follow-

ing choices:

• When selecting the device profile when configuring the Option Board

(Step 1 of section 3-1 Configuring the Option Board), select the PROFId-

rive device profile by setting P182 to 0.

• When configuring the process area content (of section 3-1 Configuring the Option Board), set all parameters (P160 - P179 to 0).

• When choosing the module while configuring the network (Step 6 of section 3-2 Configuring the Network), select either the PPO Type 2 or PPO

Type 5 module.

If you configured everything correctly, your output and input process areas should contain the following data:

Table 14 Output Process Area

!WARNING A revision AAAA Inverter allows the motor to run immediately if a trip condition

is reset, and at the same time, Run (STW) is set. For safe operation clear Run (STW) when you detect a rising-edge on Flt (ZSW). Refer to section 1-1-2 Inverter Support to determine the Inverter revision.

Table 15 Input Process Area

Note 1 Depending on your source selection, CS may already be 1 on your setup.

Note 2 For compatibility, some unsupported bits in ZSW are always 1.

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

ating the Inverter remotely via the PROFIBUS network.

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

4-1 Source Selection

First select the appropriate control and frequency sources, before operating the Inverter. We will be using the 1

motor:

Step 1 Set A001=4 and A002=4 so that the Inverter is controlled by the default PRO-

FIdrive control and frequency references registers.

Set A001=5 and A002=5 so that the Inverter is controlled by the default PROFIdrive control and frequency references registers.

Note The control override bit in the PROFIdrive control word (Section B-2 Control

and Status Words - STW/ZSW) can be used to override A001, A201, A002

and A202. When this bit is set, it has the same effect as temporarily setting A001, A201, A002 and A202=4. Clearing this bit removes the override, and the Inverter sources are once again determined by these registers.

If you are using a version AAAA Inverter, the control override bit is always disabled if A002 = 2.

Operating the Motor Section 4-2

4-2 Operating the Motor

4-2-1 Starting the Motor

Step 1 Set the En bit to enable controlled acceleration and deceleration of the motor.

Step 2 Set the Run 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 (Section 4-1 Source Selection).

Step 3 Set HIW=1000 (10.00 Hz forward).

Table 16 Output Process Area with Motor Started

The motor accelerates until it reaches the desired frequency. Notice that the FA bit is set once the inverter has reached the desired reference frequency.

Table 17 Input Process Area with Reference Frequency Reached

4-2-2 Changing Direction

Step 4 Set HIW=-1000 (10.00 Hz reverse).

Table 18 Output Process Area with Motor Set to Run Reverse

The motor decelerates, stops and then accelerates in the opposite direction. The FA bit clears as soon as the reference frequency is changed. Once the new reference frequency is reached, the FA bit is once again set.

Table 19 Input Process Area with Reverse Frequency Reached

Page 46

Operating the Motor Section 4-2

4-2-3 Stopping the Motor - Controlled

Step 5 Clear the Run bit to bring the motor to a controlled stop.

Table 20 Output Process Area for Controlled Stop

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

Table 21 Input Process Area after Controlled Stop

Before continuing set HSW to 0.

Note The motor can also be brought to a stop by setting HSW to 0 and leaving the

Run bit set. The Inverter will however stay in run mode once the motor has stopped.

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

An alternative to Step 5 is to clear the En bit to request a free-run stop: The Inverter stops controlling the motor, and the motor coasts to a stop. During a free-run stop, you will notice that HIW immediately drops to 0 and the FA bit is cleared.

4-2-5 Jog Operation

Step 6 Set the JF bit to start the jog operation.

Table 22 Output Process Area with Motor Jogging Forward

The motor immediately starts rotating forward at the pre-set jog frequency. The Inverter jog frequency can be set by adjusting Inverter parameter A038. When jogging, the Inverter immediately jumps to the jog frequency. No controlled acceleration is performed and the FA bit is immediately set.

Page 47

Customising the Process Area Section 4-3

Table 23 Input Process Area with Motor Jogging Forward

Note 1 To jog the motor in reverse, set the JR bit.

4-2-6 Frequency Reference and Output Frequency Scaling

HSW and HIW are signed word registers. Using normal scaling, you will therefore not be able to set HSW higher than 327.67 Hz (327.68 Hz in reverse).

The MX2 Inverter can however be set to operate in HF mode. Refer to the MX2 User Manual section 3-6-24 for instructions on how to achieve this.

Doing this changes the scaling of HSW and HIW to 0.1 Hz. At 0.1 Hz scaling you will be able to reach the full frequency range of the inverter by adjusting HSW.

4-3 Customising the Process Area

The PROFIdrive device profile also gives you the capability to customise the process area by mapping your choice of Modbus registers. Normally, P160, P161, P170 and P171 are set to 0 so that STW, HSW, ZSW and HIW are exchanged. The remaining parameters (P162 - P169 and P172 - P179) are normally used to map additional Modbus registers into the cyclically exchanged process areas. User parameters P160 - P169 configure the output process area mappings where parameters P170 - P179 configure the input process area mappings.

4-3-1 Double-word Frequency Reference and Output Frequency

HSW and HIW are signed word registers. Using normal scaling, you will therefore not be able to set HSW higher than 327.67 Hz (327.68 Hz in reverse) unless you are using the Inverter HF mode. You can however directly use the Inverter DWORD registers F001 and d001 to increase the usable range:

These two registers offer fixed 0.01 Hz scaling while still allowing you to control the Inverter through its full frequency range. When using the PROFIdrive device profile, the F001 and d001 registers are also sign converted by the Option Board. You can therefore use F001 and d001 as functional substitutes for HSW and HIW.

Step 1 Set parameters P161 and P162 to 0001h and 0002h to map Modbus registers

0001h and 0002h (Function code F001) into output PZD2 and PZD3.

Step 2 Set parameters P171 and P172 to 1001h and 1002h to map Modbus registers

1001h and 1002h (Function code d001) into input PZD2 and PZD3.

Step 3 Set A001=3 to use F001 as the Inverter frequency source (Note that you can-

not make use of the Ovr bit in STW to take control of the Inverter when using F001 to control the reference frequency).

Step 4 Restart the Inverter or reset the Option Board for the changes to take effect.

Page 48

Customising the Process Area Section 4-3

Tip If the Inverter trips after restarting, check that you correctly set P161, P162,

P171 and P172, and that all other registers in the P160 - P179 range are set to 0.

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

Table 24 Output Process Area with Double Word F requency Ref e rence

Table 25 Input Process Area with Double Word Output Frequency

Step 5 To turn the motor forward, set the Run and En bits in STW and change F001

(output PZD2 and PZD3) to the desired frequency. (Input PZD2 represents the most-significant word and input PZD3 the least-significant word)

Table 26 Output Process Area with Forward Rotation Dword Frequency Reference

The output frequency is given by d001 (input PZD2 contains the most-significant and input PZD3 the least-significant word).

Table 27 Input Process Area with Forward Rotation Dword Output Frequency

Step 6 To reverse the motor, change F001 (output PZD2 and PZD3) to a negative

signed double-word frequency.

Table 28 Output Process Area with Reverse Rotation Dword Frequency Reference

The motor decelerates, stops and then accelerates in the opposite direction.

Table 29 Input Process Area with Reverse Rotation Dword Output Frequency

The remainder of the examples do not make use of double-word frequency registers. Set P160, P161, P170 and P171 back to 0, A001 back to 4 and restart the Inverter or reset the Option Board before following further examples.

Note If you want to use a DINT to write or read an Inverter double-word register,

you will have to swap the high- and low-word in your PLC program (For double-words, an OMRON PLCs does not use the same word-order convention than the Inverter).

Page 49

Customising the Process Area Section 4-3

4-3-2 Mapping Coil Data 0

Modbus coils 0000h though 000Fh offer a large amount of functionality. The intelligent input terminal overrides (Coils 0007h though 000Dh) for example can be used to control any of the Inverter's assignable input terminal functions.

Refer to section 3-7-2 of the MX2 Inverter User's manual.

Refer to section 4-2 ”Multi-function input selection” of the RX Inverter User's manual.

The following example illustrates how to map Modbus coils 0000h though 000Fh into PZD3:

Step 1 Set parameters P162 to 1F01h to map coil data 0 into output PZD3.

Step 2 Restart the Inverter or reset the Option Board for the changes to take effect.

Table 30 Output Process Area with Modbus Coil Data 0

Note 1 It is not possible or practical to use all the coils contained in Coil data 0 when

the Option Board is using the PROFIdrive device profile:

• The operation (0001h) and rotation direction (0002h) coils are not used by the Inverter when the run command source (A002) is set to 4 or 5 (Option Board).

• The trip reset coil (0004h) duplicates the functionality of Rst in STW.

• The operation status coil (000Fh) is not writeable.

Step 3 The Modbus coils 0000h though 000Fh are now available for use via PZD3.

Use parameters C001 to C007 to assign Inverter functions to any of the intelligent input terminals. To activate an assigned function, set the corresponding input terminal override (bits 7 to 13 in coil data 0).

4-3-3 Controlling Inverter Torque

In addition to frequency control, the 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:

Step 1 Set parameter P162 to 1F01h to map coil data 0 into output PZD3.

Step 2 Set parameter P163 to 1622h to map the torque command level input (P034)

into output PZD4.

Step 3 Set parameter P173 to 1010h to map the torque monitor (d012) into input

PZD4.

Customising the Process Area Section 4-3

Step 4 Set parameter C001=52 (ATR: permission of torque command input) to use

intelligent input terminal 1 as torque enable.

Prepare the Inverter for torque mode:

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

• Refer to section 4-3 of the RX User manual (I560) to set the torque mode.

Step 5 Set parameter P033=6 to assign Torque command input selection to the

Option Board Interface.

Set parameter P033=7 to assign Torque command input selection to the Option Board Interface 2.

Step 6 Restart the Inverter or reset the Option Board for the new settings to take

effect.

Restart the Inverter or reset the Option Board for the new settings to take effect. If the Inverter trips after restarting with an E64 / E74 and parameters P162, P163 and P172 appear to be configured correctly, it is likely that you made a mistake in Step 1 or Step 2 (The Inverter will only allow mapping of torque registers in the process area if it is configured to operate with CT rating in Std. IM mode).

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:

Table 31 Output Process Area Configured for Torque Control

Table 32 Input Process Area Configured for Torque Control

Step 7 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.

Step 8 Set the En and Run bits in STW to enable controlled acceleration and decel-

eration and put the Inverter in run mode.

Step 9 Set HIW=+1000 (10.00 Hz forward) to accelerate the motor to a constant for-

ward output frequency.

Step 10 Select the desired output torque by setting P034 (output PZD4)=+20 (20%

forward torque).

Step 11 Set the ATR bit in coil data 0 (output PZD3) to enable torque command input.

Page 51

Customising the Process Area Section 4-3

Table 33 Output Process Area Configured with Forward Torque Command

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 (input PZD4).

Step 12 To change the torque command direction, set both HSW=-1000 (10.00 Hz

reverse) and P034 (output PZD4)=-20 (20% reverse torque).

Table 34 Output Process Area Configured with Reverse Torque Command

The motor decelerates and accelerates in the opposite direction. The output frequency is limited by the P040 setting. Note that the output torque given by d012 (input PZD4) now has a negative sign to indicate that the torque direction is reversed.

Tip To keep your application compatible with all revisions of the Inverter, keep the

sign of HIW and P034 the same.

The torque direction is controlled by the sign of HIW when using the Inverter revision AAAA. On later releases, the sign of P034 controls the torque direction.

4-3-4 Mapping Restrictions

Before you start customizing the process area, it is necessary to note the Inverter places some restrictions on the customizing.

If your configuration is rejected by the Inverter, you got assist in sections 5-1- 3 Configuration Errors and 5-2-2 Extended Diagnostic Information of this

manual.

If you want to avoid configuration rejection, observe the following rules for the MX2:

• Set all unused PZDs to default by setting the associated configuration register to 0.

• Only map Modbus registers listed in appendix B of the MX2 Inverter user's manual.

• Do not map a Modbus register more than once in the output process area.

• Always map both high- and low-words of a double-word Modbus register next to each other in the process area. Also make sure that they are in the correct sequence (high-word followed by low-word).

Page 52

Faults and Trips Section 4-4

• Only map a Modbus registers in the output process area if it is writeable. A register is writeable if it has an 'R/W' or a 'W' in the 'R/W' column in section B-4-2 of the MX2 Inverter user's manual.

• Only map a Modbus register in the output process area if it is run-mode editable. Refer to section 3-2-3 of the MX2 Inverter user's manual for an explanation of run-mode editable registers. Also note that the run-mode edit requirement can be disabled with b031.

If you want to avoid configuration rejection, observe the following rules for the RX:

• Set all unused PZDs to default by setting the associated configuration register to 0.

• Only map Modbus registers listed in section 4.4 Register Number List of the RX Inverter user's manual.

• Do not map a Modbus register more than once in the output process area.

• Always map both high- and low-words of a double-word Modbus register next to each other in the process area. Also make sure that they are in the correct sequence (high-word followed by low-word).

• Only map a Modbus registers in the output process area if it is writeable. A register is writeable if it has an 'R/W' or a 'W' in the 'R/W' column in section 4.4 Register Number List of the RX Inverter user's manual.

• Only map a Modbus register in the output process area if it is run-mode editable. Refer to Appendix 1 of the RX Inverter user's manual for an explanation of run-mode editable registers. Also note that the run-mode edit requirement can be disabled with b031.

4-4 Faults and Trips

4-4-1 External Trip

You may want to trip the Inverter from your PLC program. The PROFIdrive device profile does not provide a standard interface to achieve this, but you can use the Modbus coil number 0003h to generate an external trip (EXT):

Step 1 Follow the instructions in section 4-3-2 Mapping Coil Data 0 to map Coil data

0 into PZD3.

Step 2 Set bit 3 (EXT) of Coil data 0 which has been mapped into PZD3 to trip the

Inverter.

Table 35 Output Process Area when Using EXT to Trip Inverter

Page 53

Accessing Parameters Section 4-5

Table 36 Input Process Area with Inverter Tripped

Note 1 Notice that the Inverter trips with an E12, the Flt bit is set and the Rdy bit

cleared.

4-4-2 Clearing a Trip

!WARNING In the event that the Inverter trips, be sure to investigate the cause of this trip

thoroughly before clearing the trip. Not checking the cause may result in

unexpected operation. Refer to section 5-1 Troubleshooting using the LED indicators or section 5-2 Troubleshooting Using PROFIBUS Diagnostics.

Step 3 You must always immediately clear the Run bit in your PLC program when a

rising edge is detected on Flt. If the Run bit is set when the trip condition is cleared, the Inverter will immediately start running!

Step 4 Set the Rst bit in the STW register to clear the trip.

Table 37 Output Process Area when Clearing Trip

!WARNING Always clear the Run bit (STW) in your PLC program on a rising-edge of Flt

(ZSW). Not doing so may result in the motor starting unexpectedly when the trip is cleared via PROFIBUS or the "Stop/reset" button on the Inverter.

4-5 Accessing Parameters

4-5-1 Parameter Processing Message Area - PKW

Table 38 Input and Output Parameter Processing Message Area-PKW

Page 54

Accessing Parameters Section 4-5

You can use the parameter processing message area to read or write parameters via the output- and input process areas. You can use any of the following tasks by writing the task number to AK in the output process area.

Some parameters contain arrays and have to be accessed using array tasks (Tasks 6, 7 and 8). Array tasks use IND to address the element number in an array.

When the Option Board completes the task, a task response is written to AK in the input process area. The size of the parameter is given by the task response number.

If you executed an array tasks, you will accordingly receive an array task response ID (Task response 4, 5 or 8).

When a read task succeeds, the Option Board also writes the value to PWE in the input process area.

When you start a write task, you must also write the new parameter value to PWE in the output process area.

When a task fails, the Option Board writes a 7 or 8 (Task failed) to AK and an error number to PWE in the input process area. All error numbers are listed in

APPENDIX G PROFIdrive Error Numbers.

Note If you want to use a DINT to write or read PWE, you will have to swap the

high- and low-word in your PLC program (For double-words, an OMRON PLCs does not use the same word-order convention than PROFIBUS).

Note The parameter processing message area is only available when using the

PPO Type 1, PPO Type 2 or PPO Type 5 module. To access parameters when using the PPO Type 3 or PPO Type 4 module, make use of the PRO-

FIdrive DP-V1 parameter channel (Refer to section 4-5-2 PROFIdrive DP-V1 Parameter Channel).

Tip Use the following sequence when starting a read or write task:

1. Set AK=0.

2. Set PNU, IND and PWE.

3. Set AK to the desired task.

The parameter processing message mailbox is triggered by a change in the parameter processing output area. By first setting AK=0, you avoid unintentionally starting a write task when you start changing PNU, IND and PWE.

4-5-1-1 Accessing Option Board Parameters

Option Board parameters are addressed by writing the parameter number to

PNU (Refer to APPENDIX F Option Board Parameters for a list of the avail-

able Option Board parameters). If you are addressing an element in an Option Board parameter array, you must also write the element index to IND. When writing an Option Board parameter, the task number specifies the write size.

The following example demonstrates how to use the parameter process message area to access Option Board parameters:

Step 1 Reading an Option Board Parameter: To read Option Board parameter 965

(Unit profile code): First set PNU and then AK as illustrated below. The Option Board will respond with the illustrated values.

Step 2 Reading an Option Board array element: To read Option Board parameter

element 915.3 (Modbus address mapped into PZD3): Set PNU=393h (915 dec), AK=6 and IND=3.

Step 3 Changing an Option Board array element: To change Option Board param-

eter element 915.3 (Modbus address mapped into PZD3) to 1F01h (Coil data

0):

Accessing Parameters Section 4-5

Step 4 Storing changed parameter(s): To store changed parameter(s) in non-vola-

tile memory, write a 1 to Option Board parameter 971:

Step 5 Resetting the Option Board: To reset the Option Board, write a 2 followed

by a 1 to Option Board parameter 972:

Without changing AK or PNU, set PWE=1

The Option Board correctly executes the task and resets before responding. After the PROFIBUS master has re-connected, the Option Board tries to execute the task a second time. The task fails because parameter 972 may only be set to 1 if the current value is 2.

4-5-1-2 Accessing Inverter Parameters

When you address Inverter parameters, IND is used to select the parameter group.

PNU represents the parameter number in that group. To address P160 for example set IND=10h (P@@@) and PNU=0A0h (160).

Note It is important to use array tasks (6, 7 or 8) when accessing Inverter parame-

ters. IND is only interpreted if the Option Board executes an array task.

Accessing Parameters Section 4-5

!Caution Do not access Inverter parameters while the Inverter is being re-initialized.

Refer to the MX2 Inverter manual section 6-3.

Refer to the RX Inverter manual section 4-2.

Accessing parameters during a re-initialization will cause the Inverter to go into an undefined state.

4-5-2 PROFIdrive DP-V1 Parameter Channel

The Option Board provides Parameter Access in accordance

with the PROFIdrive V4 profile definition. Access is only supported on DP-V1 Class 2 slot 0, index 47. You will therefore have to ensure that all MSAC2_Initialize, MSAC2_Write, MSAC2_Read and MSAC2_Abort messages make use of slot 0, index 47.

Note The OMRON web-site (http://industrial.omron.eu) provides function blocks

that automate parameter access when using the CJ1W-PRM21 / CS1WPRM21 version 3.0 or newer. These function blocks automate the DP-V1 Class 2 related commands to the PROFIBUS master as well as the DP-V1 parameter channel request and response formats. You can skip this section if you are using these function blocks.

!Caution Do not access Inverter parameters while the Inverter is being re-initialized.

Refer to the MX2 Inverter manual section 6-3.

Refer to the RX Inverter manual section 4-2.

Accessing parameters during a re-initialization will cause the Inverter to go into an undefined state.

4-5-2-1 Opening and Closing a DP-V1 Channel

Before the PROFIBUS master can exchange information with the Option Board, the PROFIBUS master has to open a DP-V1 Class 2 (MSAC2) channel to the Option Board. Please consult the documentation of your PROFIBUS master on how to achieve this.

The Option Board only supports one DP-V1 Class 2 (MSAC2) channel. It is therefore advisable to close the channel when you are done. Not doing so will block other users of the parameter channel. Consult the documentation of your PROFIBUS master on how to achieve this.

Accessing Parameters Section 4-5

4-5-2-2 DP-V1 read/write sequence

The following illustration demonstrates the DP-V1 read/write sequence.

1. The PROFIBUS master generates an MSAC2_Write request with parameter instructions. The write instructs the Option Board to either read or change a number of parameters.

2. If the MSAC2_Write request is valid, the Option Board responds with a positive write response but no data. If the MSAC2_Write request is invalid, the Option Board responds with a DP error.

3. The Option Board starts processing and executing the parameter instructions:

• While the Option Board is processing read instructions, it fills the result data with parameter values. If the Option Board encounters an error, the corresponding value is replaced with a PROFIdrive error number

(Refer to section E-5 Parameter Value Formats).

• While the Option Board is processing change instructions, it generally does not generate result data. However, if it encounters and error the result data is filled with either zero-data (no error) or the corresponding

error value and element index (Refer to section E-5 Parameter Value Formats).

4. The master polls the Option Board with an MSAC2_Read request.

5. While the Option Board is busy executing the instructions, it responds with a negative read response (state conflict).

6. Once the Option Board is finished with the parameter instructions and the result is available, it responds with a positive read response, and the instruction result + data.

Note Consult the documentation of your PROFIBUS master to obtain information

on how the above sequence may be automated.

4-5-2-3 Accessing Option Board Parameters

The following example demonstrates how to use the DP-V1 Class 2 (MSAC2) parameter channel to read an Option Board parameter:

Note It is outside the scope of this manual to explain the DP and DP-V1 headers

and trailers. They are however shown in the illustrations to make the context of the message data visible.

Step 1 Open a DP-V1 Class 2 (MSAC2) channel to the Option Board (Refer to the

documentation of your PROFIBUS master on how to open and close a DP-V1 channel)

Instruct the Option Board to read parameter 965 (Unit profile code):

Page 60

Accessing Parameters Section 4-5

When the Option Board responds with the result, process the response:

Step 2 Instruct the Option Board to read parameter elements 915.1 - 915.4 (Modbus

addresses mapped into PZD1 - PZD4):

When the Option Board responds with the result, process the response:

Step 3 Instruct the Option Board to change parameter elements 915.3 - 915.4 (Mod-

bus address mapped into PZD3 - PZD4) to 1F01h (Coil data 0) and 1622h (P034 - Torque command level input):

Step 5 Instruct the Option Board to change parameter 972 first to 2, then to 1 (reset

the Option Board):

If the Option Board responds with result data, the reset failed. When the Option Board is reset, the DP-V1 Class 2 (MSAC2) channel is automatically closed. The details of the change instruction are therefore lost.

Step 6 Re-open the DP-V1 Class 2 channel to the Option Board before continuing

with further examples (Refer to section 4-5-2-1 Opening and Closing a DP-V1 Channel)

Note The DP-V1 Class 2 (MSAC2) channel parameter channel is automatically

closed when resetting the Option Board. You will therefore have to re-open the channel before you can perform further parameter accesses.

4-5-2-5 Processing an Error Response

When the Option Board is unable to execute one of the read parameter instructions, it adds an error value to the result data. Reading parameters A001, A166 and P033 for example:

Has the following result:

Note that the value of parameter A166 is replaced with an error value in the result data. Inverter parameter A166 does not exist, so error number 0000h (Bad parameter number) is returned. Note that the values of A001 and P033 are returned irrespective of other read errors.

Note If a read on one of the elements in an array fails, an error is returned on the

parameter. Successfully read elements can therefore not be returned.

Flexible Mode Section 4-6

When the Option Board is unable to execute one of the write parameter instructions, it adds an error value and the failed element index to the result data. Changing Option Board parameter elements 915.9 - 915.12 for example:

Has the following result:

Note that the error number is followed by the element number where the change instruction failed. I.e. The changes to Option Board parameter elements 915.9 and 915.10 were carried out successfully. The attempt to change

915.11 failed and changes to subsequent elements (915.12) were not carried out.

4-6 Flexible Mode

The Flexible device profile lets you operate the Inverter using the Modbus registers directly. Parameters P160 - P169 and P170 - P179 can be used to map Modbus registers into the cyclically exchanged process areas. User parameters P160 - P169 configure the output process area mappings where parameters P170 - P179 configure the input process area mappings.

!WARNING A revision AAAA MX2 Inverter allows the motor to run immediately if a trip

condition is reset, and at the same time, Opr (Coil data 0) is set. For safe operation clear Opr (Coil data 0) when you detect that InvStat A changes to 8. Refer to section 1-1-2 Inverter Support to determine the MX2 Inverter revision.

4-6-2 Operating the Motor

Step 8 Set A001=3 and A002=3 so that the Inverter can be controlled using the Mod-

bus registers.

Step 9 Set the Opr 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.

Step 10 Change d001 to the desired frequency (E.g. 1000 for 10.00 Hz)

Table 75 Flex Mode Output Area with Motor Running Forward

The motor accelerates until it reaches the desired frequency. Notice that the FA1 bit is set once the inverter has reached the desired reference frequency.

Table 76 Flex Mode Input Area with Motor Running Forward

Step 11 Set Dir to reverse the direction of the motor. The motor decelerates, stops and

then accelerates in the opposite direction. The FA1 bit clears as soon as the reference frequency is changed. When the motor starts reversing, the Dir bit in Coil data 1 is set. Once the new reference frequency is reached, the FA1 bit is once again set.

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

halt.

4-6-3 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 AL bit in Coil Data 1 (Tripping) is set by the inverter. If the Opr bit is set when the trip condition is cleared, the Inverter will immediately start running!

Page 69

Limitations Caused by Inverter Mode and Rating Selection Section 4-7

!WARNING Always clear the Opr bit in your PLC program when Inverter status A is set to

8 (Tripping) 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.

5-1 Troubleshooting using the LED indicators

The four 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 indicator pattern provides troubleshooting information. For certain errors, additional information can be obtained from the trip error code given by the four-digit display of the Inverter.

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:

5-1-1 When an error occurs

When an error occurs, the Option Board trips the Inverter.

Step 1 For the MX2 Inverter, an error code is displayed on the Digital Operator Dis-

play.

For the RX Inverter, you need to connect the Digital Operator Display to the Inverter with an Ethernet cable. Then you can see the error code on the display. Note: if despite the problem it is still possible to communicate with the unit, the latest error code can also be read in parameter d081.

Step 2 Use the error code to help troubleshoot the error.

Glossary

Device Profile A device profile defines a common interface and behavior for a range of

devices that can be grouped under a particular class.

DP-V1 DP-V1 implements PROFIBUS Acyclic data exchange, cyclic data exchange

and alarm handling at the application layer.

DP-V1 Class 2 DP-V1 Class 2 (also known as MSAC2) messaging supports communication

relationships between the PROFIBUS DP slave and multiple PROFIBUS DP masters.

EMC EMC (ElectroMagnetic Compatibility) defines the extent to which a piece of

hardware will tolerate electrical interference from other equipment, and will interfere with other equipment.

EMI Electromagnetic Interference - In motor/drive systems, the switching of high

currents and voltages creates the possibility of generating radiated electrical noise that may interfere with the operation of nearby sensitive electrical instruments or devices. Certain aspects of an installation, such as long motor lead wire lengths or an ungrounded chassis, tend to increase the chance of EMI.

FA Systems Factory Automation Systems implement control systems in combination with

other applications of information technology to control industrial machinery and processes. FA Systems are used to reduce the need for human intervention in factory environments.

Fieldbus Fieldbus is the name of a family of industrial computer network protocols used

for real-time distributed control, now standardized as IEC 61158

Free-run Stop A method of stopping a motor, caused when the Inverter simply turns OFF its

motor output connections. This may allow the motor and load to coast to a stop, or a mechanical brake may intervene and shorten the deceleration time.

Frequency Setting While frequency has a broad meaning in electronics, it refers to motor speed

for motor and drive systems. The output frequency of an Inverter is variable and proportional to the attained motor speed.

Intelligent Terminal A configurable input or output logic function on the Omron Inverters. Each ter-

minal may be assigned one of several functions.

Inverter A device that electronically changes DC to AC current through an alternating

process of switching the input to the output, inverted and non-inverted. It contains three Inverter circuits to generate 3-phase output to the motor.

Jogging Operation Usually done manually, a jog command from an operator's panel requests the

motor/drive system to run indefinitely at low speed in a particular direction. This continues until the machine operator ends the jog operation.

PLC A PLC (Programmable Logic Controller) is a digital computer used for the

automation of electromechanical processes.

Process Area The Process Area is a memory area in the controller that allows you to control

and monitor the Unit. The Fieldbus is used to continually refresh the Process Area to and from decentralized peripherals. A Unit's status- and response to a change in the Process Area therefore isn't instantaneous (The latencies and jitter associated with the communication path limit the responsiveness of the Unit).

APPENDIX A

PROFIBUS PROFIBUS (PROcess FieldBUS) is a standard for Fieldbus communication in

automation technology

PROFIBUS DP PROFIBUS DP (PROFIBUS for Decentralised Peripherals) is an implementa-

tion of PROFIBUS optimized for distributed I/O applications. PROFIBUS DP devices can co-exist with non-DP PROFIBUS devices on the same bus.

PROFIBUS FMS PROFIBUS FMS (PROFIBUS Fieldbus Message Specification) is an imple-

mentation of the PROFIBUS tailored for demanding communication tasks. PROFIBUS FMS devices can co-exist with non-FMS PROFIBUS devices on the same bus.

PROFIdrive PROFIdrive implements a common PROFIBUS DP device profile for motion

control applications such as drives and Inverters.

Programmable Products Some products allow customisation of their behavior by allowing the execution

of a sequence of user instructions.

Termination Electrical termination of a signal involves providing a terminator at the end of

a wire or cable. Termination prevents an RF signal from causing interference by being reflected back at the end of the cable.

Torque The rotational force exerted by a motor shaft. The units of measurement con-

sist of the distance (radius from shaft centre axis) and force applied at that distance. Units are usually given as Newton-meters, pound-feet or ounceinches.

Trip Event An undesired event that causes the Inverter to stop operation is called a "trip"

event (as in tripping a circuit breaker). The Inverter keeps a history log of trip events. They also require an action to clear.

Unit Within the context of this document, Unit refers to the MX2 or RX Option

Board.

Variable Speed Drive A Variable Speed Drive is a piece of equipment used to control the speed of

machinery.

PROFIdrive Device Profile

Acronyms HIW

The monitored output frequency is called HIW in the PROFIdrive device profile.

HSW The commanded frequency reference is called HSW in the PROFIdrive device

profile.

PKE The combination of the task ID and parameter number in the PKW messaging

area is called PKE in the PROFIdrive device profile.

PKW The parameter processing messaging area is called PKW in the PROFIdrive

device profile.

PNU The parameter number is called PNU in the PROFIdrive device profile.

PWE The parameter value in the PKW messaging area is called PWE in the PRO-

FIdrive device profile.

PZD The process data (cyclically transferred) is called PZD in the PROFIdrive

device profile.

STW The control word is called STW in the PROFIdrive device profile.

ZSW The status word is called ZSW in the PROFIdrive device profile.

Page 89

APPENDIX B

Parameter Process Data Object Modules

The Parameter Process Data Object (PPO) modules implement the cyclic data exchange mapping for the PROFIdrive device profile. Five modules are supported (PPO1 - PPO5) allowing you to select the number of exchanged registers and PKW messaging support. All modules provide two default output words: STW (Control word) and HSW (Frequency Reference), provide control over the Inverter. All modules additionally provide two default input words: ZSW (Status Word) and HIW (Output Frequency) provide feedback on

the Inverter status. STW and ZSW are explained in more detail in appendix B-

2. HSW and HIW are explained in appendix B-3. The exchanged Modbus reg-

isters are configured by setting Inverter registers P160 - P179 to the appropriate Inverter Modbus addresses. If P160, P161, P170 or P171 are set to 0, STW, HSW, ZSW and HIW are used.

Note Set P182 = 0 for the Option Board to support the PPO modules

Note The Inverter places some restrictions on the Modbus register selection. For a

Modbus Register to be mapped for output data exchange, it must be a runmode edit register that provides write-access. Double-word Modbus registers must be mapped in sequence: high-word following low-word. It is not allowed to map the same register more than once in the output area.

Tip

Refer to section B-4-2 of the MX2 Inverter user’s manual for a list

of the Inverter registers that provide write access.

Tip Refer to section 5 of the RX2 Inverter user’s manual for a list of the Inverter registers that provide write access.

Tip

Refer to section 3-2-3 of the MX2 Inverter user’s manual for an

explanation on run-mode edit registers. Also note that the run-mode edit requirement can be disabled with b031.

Tip Refer to section 5 of the RX Inverter user’s manual for an explanation on run-mode edit registers. Also note that the run-mode edit requirement can be disabled with b031.

Control and Status Words - STW/ZSW APPENDIX B

B-2 Control and Status Words - STW/ZSW

Note The PZD1 output and input registers will control STW and present ZSW only if

P160 = 0 and P170 = 0

Note 1 When jogging, the output frequency is controlled by A038

Note 2 When the Control Override is not set, the Control- and Frequency Sources are

determined by A001/A002 or A201/A202

Note 3 When the Control Override is set, PROFIBUS takes over as both Control- and

Frequency Source irrespective of A001/A201/A002/A202

B-3 Frequency Reference and Output Frequency - HSW/HIW

The HSW output register controls both the Option Board Frequency Reference and Run Direction. The Run Direction is determined by HSW's sign and the Frequency Reference by HSW's absolute size. Normally HSW has a scaling of 0.01 Hz. If the Inverter is operated in HF mode, the scaling is 0.1 Hz.

Note The PZD2 output register will control HSW only if P161 = 0

The HIW input register represents both the Inverter Run Direction and Output Frequency. The Run Direction is represented by HIW's sign and the Output Frequency by HIW's absolute size. Normally HIW has a scaling of 0.01 Hz. If the Inverter is operated in HF mode, the scaling is 0.1 Hz.

Note The PZD2 input register will present HIW only if P171 = 0

APPENDIX D

Flexible Module

The Flexible Format implements I/O data exchange that supports direct mapping of Inverter Modbus registers in the I/O area. This offers fieldbus- and profile-independent control of the Inverter. The exchanged registers are configured by setting Inverter registers P160 - P179 to the appropriate Inverter Modbus addresses.

Note Set P182 = 2 for the Option Board to support the Flexible module

Note The Inverter places some restrictions on the Modbus register selection. For a

Modbus Register to be mapped for output data exchange, it must be a runmode edit register that provides write-access. Double-word Modbus registers must be mapped in sequence: low-word following high-word. It is not allowed to map the same register more than once in the output area.

Refer to Section B-4-2 of the MX2 Inverter user's manual for a list of the Inverter registers that provide write access.

Refer to Section “4-4 Register Number List” of the RX Inverter user's manual for a list of the Inverter registers that provide write access.

Refer to Section 3-2-3 of the MX2 Inverter user's manual for an explanation on run-mode edit registers. Also note that the run-mode edit requirement can be disabled with b031.

Refer to Appendix 1 of the RX Inverter user's manual for an explanation on run-mode edit registers. Also note that the run-mode edit requirement can be disabled with b031.

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

I.e. set A001/A002 = 3 and A201/A202 = 3 to make use of the Modbus control registers for typical Flexible Module use.

The Modbus addresses for the MX2 Inverter are listed in section B-4-2 of the MX2 user's manual.

The Modbus addresses for the RX Inverter are listed in “Section 4-4 Register Number List” of the RX user's manual.

P160 - P169 can also be accessed as PNU915.1 - PNU915.10 P170 - P179 can also be accessed as PNU916.1 - PNU916.10

Note Irrespective of the user configuration, the size of the module is fixed to 10

words in and 10 words out.

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 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 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 Inverter are listed in section B-4-1 of the MX2 user's manual.
