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 electrical 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 personnel. 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-CRT-E CompoNet 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-CRT-E CompoNet 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 connector 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-cir- cuits 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 CompoNet Master Units Operation Manual (Cat. No. W456):

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

•Be sure that the network connectors are clicked into place correctly. Improper latching may result in malfunction.

•Always connect a Terminating Resistor at the prescribed locations of the CompoNet 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 CompoNet node address and CompoNet 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.

xi

Application Precautions

•When replacing an Option Board be sure that the setting of the rotary switches of the Option Board being replaced are restored to the replacement.

•Restoring parameters stored in the remote operator also restores the CompoNet 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-CRT-E allows controlling, monitoring and parameterization
	of an MX2-A@ Inverter via a CompoNet network. The 3G3AX-MX2-CRT-E
	serves as a gateway that passes communicated register values from the
	CompoNet network to the MX2-A@ Inverter and vice versa. The
	3G3AX-MX2-CRT-E adheres to the CompoNet / CIP AC Drive profile.
	The following functions are available via CompoNet communication by install-
	ing the 3G3AX-MX2-CRT-E:
Cyclic Data Exchange	The CompoNet Master and 3G3AX-MX2-CRT-E can exchange data via a
	CompoNet Remote I/O connection:
	• Output data (from CompoNet Master to 3G3AX-MX2-CRT-E):
	E.g. Run/stop, Reference frequency and Fault reset.
	• Input data (from 3G3AX-MX2-CRT-E to CompoNet Master):
	E.g. Inverter status, Output frequency and Output current, etc.
Inverter Parameter Access	The CompoNet Master can read and write parameter data via the
	3G3AX-MX2-CRT-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-CRT-E can be set up easily, just by wiring the Unit, setting
	the CompoNet node address by either the rotary switches or by setting
	inverter parameter (P190) and the default connection path (P046) and restart-
	ing 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 spe-
	cial Programming Device.
Simplified Replacement	All parameters required by the 3G3AX-MX2-CRT-E are stored in the MX2-A@
	Inverter. The 3G3AX-MX2-CRT-E can be replaced, requiring no re-configura-
	tion.
Automatic Baud Rate	The 3G3AX-MX2-CRT-E automatically detects the Master’s communication
Recognition	baud rate, and no user configuration is required.

1-3 Introduction to CompoNet

1-3-1 Overview of CompoNet

CompoNet Networks feature easy operation and installation in a componentlevel network connecting PLCs and on-site I/O. The PLC and CompoNet Slave Units cyclically exchange I/O information through a CompoNet Master Unit, refreshing I/O in sync with the PLC scan. CompoNet (just like 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.

1-3-2 CompoNet Slave Unit Groups

	CompoNet Slave Units can be classified into the following groups:
Word Slave Units	Word Slave Units are Slave Units that are allocated units of 16 bits (i.e., 1
	word) in I/O memory of the CPU Unit.
Bit Slave Units	Bit Slave Units are Slave Units that are allocated units of 2 bits in I/O memory
	of the CPU Unit. Bit Slave Units provide 2 or 4 digital contact I/O points and
	have Standard or Sheathed Flat Cable already connected.
Repeater Units	Units that can be used to expand the network by extending trunk lines or
	branching

1-3-3 What is the AC Drive profile

Within CompoNet/CIP standard, multiple device profiles have been defined.

Therefore the devices which adhere to a certain device profile are compatible.

The AC Drive device profile (profile code 0x02) supplements the CompoNet/ 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.

2-1-4 Rotary Switches

The rotary switches are used to set the node address of the 3G3AX-MX2- CRT-E Option Board on the CompoNet network. Set the node address as a decimal number between 0 and 63.

Set the 10s digit on the left rotary switch and set the 1s digit on the right rotary switch. The setting of the switches is read when the Unit power supply turns ON.

There are two ways of configuring the CompoNetNode number.

1.Set the node address by the rotary switches to a valid value in the range 0 to 63.

2.Set the node address by Inverter parameter P190. Set the rotary switches to an invalid value (between 64 to 99) to set the node address as the value of the P190 parameter
