!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.
x
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

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.

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.

Introduction to PROFIBUS Section 1-3
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.
