damage to the product.
WARNING Do not operate the Operator or switches with wet hands. Doing so may result in
!
electrical shock.
WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
!
WARNING Do not come close to the machine when using the error retry function because the
!
machine may abruptly start when stopped by an alarm. Doing so may result in injury.
WARNING Do not come close to the machine immediately after resetting momentary power
!
interruption to avoid an unexpected restart (if operation is set to be continued in the
processing selection function after momentary power interruption is reset). Doing so
may result in injury.
WARNING Provide a separate emergency stop switch because the STOP Key on the Operator
!
is valid only when function settings are performed. Not doing so may result in injury.
WARNING Be sure confirm that the RUN signal is turned OFF before turning ON the power
!
supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so
while the RUN signal is turned ON may result in injury.
Caution Be sure to confirm permissible ranges of motors and machines before operation
!
because the Inverter speed can be easily changed from low to high. Not doing so
may result in damage to the product.
Caution Provide a separate holding brake when necessary. Not doing so may result in injury.
!
Caution Do not perform a signal check during operation. Doing so may result in injury or dam-
!
age to the product.

Overview Chapter 1
H Powerful Torque Ideal for a Variety of Applications
The 3G3MV is OMRON’s first compact Inverter incorporating an open-loop vector control function,
which ensures a torque output that is 150% of the rated motor torque at an output frequency of 1 Hz.
Ensures a more powerful revolution at low frequencies than any conventional inverter. Furthermore, the
3G3MV Inverter suppresses the revolution fluctuation caused by the load.
Incorporates a fully automatic torque boost function that drives the motor powerfully in V/f control.
Incorporates a high-speed current limit function, thus suppressing overcurrent caused by high torque
and ensuring smooth operation of the motor.
H Convenient Easy-to-use Functions
• The FREQUENCY adjuster of the Digital Operator allows easy operation. The default setting is for
operation according to the FREQUENCY adjuster setting.
• The Digital Operator has a parameter copy function ensuring easy parameter control.
• Ease of maintenance is ensured. The cooling fan is easily replaceable. The life of the cooling fan can
be prolonged by turning ON the cooling fan only when the Inverter is in operation.
• Incorporates a control transistor. Therefore, the Inverter will provide powerful control by just connect-
ing a braking resistor.
• Incorporates an inrush current preventive circuit that prevents contact weld at the input power supply
block.
H International Standards (EC Directives and UL/cUL Standards)
The 3G3MV Inverter meets the EC Directives and UL/cUL standard requirements for worldwide use.
Classification Applicable standard
EC Directives
UL/cUL UL508C
EMC directive EN61800-3
Low-voltage directive EN50178
H Compatible with DeviceNet and RS-422/485
• Supports RS-422 and RS-485 communications conforming to the MODBUS Communications Proto-
col, thus making it possible to easily construct networks with the use of the Protocol Macro or ASCII
Unit mounted on an OMRON SYSMAC PLC. The MODBUS Communications Protocol is a trademark
of AEG Schneider Automation.
• Connects to the 3G3MV-PDRT2 DeviceNet Communications Unit. A remote I/O function for Device-
Net communications Unit is available to the 3G3MV Inverter, which ensures ease of communications
just like standard I/O communications.
Furthermore, DeviceNet communications conform to the DeviceNet communications protocol for
open networks, thus allowing construction of multi-vendor networks in which other companies’
devices can coexist.
Note 1. MODBUS communications and DeviceNet communications cannot be performed simulta-
neously. It is necessary to select the type of communications required.
Note 2. Only DeviceNet Communications Units manufactured after January 1st, 2000 can be con-
nected to 5.5-kW and 7.5-kW Inverters. Earlier products are not compatible with these Inverters.

1-3 New Features
New features have been added to 3G3MV-Series models with 5.5-kW and 7.5-kW capacities (i.e., the 3G3MV-A2055/A2075/ A4055/A4075). These features are outlined
below and explained in detail in Chapter 6.
H New Features for 3G3MV-A2055/A2075/A4055/A4075 Only
D Enclosure Rating: Closed Wall-mounting Conforming to IP20/NEMA1
The 5.5-kW and 7.5-kW Inverters have closed wall-mounting specifications that conform to
IP20/NEMA1, so they can operate in an ambient temperature range of –10 to 40°C.
Note To operate this Inverter within an ambient temperature range of –10 to 50°C, remove the top and
bottom covers to convert it to a panel-mounting model (IP00).
D Default Settings Changed for V/f Patterns (Parameters: n011 to n017)
For 5.5-kW and 7.5-kW Inverters, two of the default settings have been changed. The default settings
for the middle output frequency voltage (VC) (n015) and the minimum output frequency voltage (VMIN
(n017) have both been changed to 10 V for 200-V-class models and to 20 V for 400-V-class models.
D Inverter Overheating Warning Input
(Parameters: n050 to n056; Fault Display: oH3)
An Inverter overheating warning input has been added as a new function that can be set for multi-function inputs 1 to 7 (n050 to n056). When this warning is input, an oH3 fault (nonfatal error) will be displayed. This input can be used for functions such as thermal contact connections for peripheral overheating detection.
D Frequency Reference Loss Detection (Parameter: n064)
When the frequency is referenced using analog frequency reference inputs (0 to 10 V/4 to 20 mA/0 to 20
mA), this function detects sudden changes in analog inputs as errors (disconnection, short circuit,
breakdown, etc.) and outputs the frequency reference loss output that is set in multi-function outputs 1
to 3 (n057 to n059). After the change is detected, operation continues at 80% of the frequency reference
prior to the change.
D Accumulated Operating Time (Monitor: U-13; Parameters: n087, n088)
This function calculates and stores in memory the Inverter’s accumulated power-ON time or RUN time.
Use it for checking and determining the maintenance schedule.
D Speed Search Adjustment (Parameters: n101, n102)
A function has been added for adjusting the speed search. (The speed search is a function for detecting
and smoothly controlling the speed of a free running motor.) The speed search operating time and
search level can be adjusted.
D Input Open-phase Detection
(Parameters: n166, n167; Fault Display: PF)
This function detects the Inverter’s input power supply open phase. Open phases are detected through
main circuit voltage fluctuations, so this function can also be used for detecting abnormal voltage fluctuations in the input power supply voltage.
1-8
Overview Chapter 1
D Output Open-phase Detection
(Parameters: n168, n169; Fault Display: LF)
This function detects open phases between the Inverter output and the motor.
D Ground Fault Detection (Fault Display: GF)
This function detects ground faults between the Inverter output and the motor.
D Load Short-circuit Detection (Fault Display: SC)
Prior to an Inverter output, this function detects whether the output is short-circuited. If short-circuiting
occurs during an output, it detects an overcurrent (oC).
H New Features for All 3G3MV Models
D Communications Error Monitor (Monitor: U-15)
This function displays communications errors that occur during serial communications
(RS-422/RS-485). The errors that are displayed have the same content as the general serial communications error at register number 003D Hex.
D Pulse Train Frequency Reference Input Filter Constant
(Parameter: n076)
This function sets the primary lag digital filter for pulse train frequency reference inputs.
D Multi-function Analog Inputs (Parameters: n077 to n079)
A function has been added to enable setting the Digital Operator’s multi-function analog voltage (current) inputs. It can set auxiliary analog inputs such as auxiliary frequency references and frequency
reference bias or gain.
Note If multi-function analog inputs are set for use with PID control, no other multi-function analog input
functions can be set or they will overlap.
H New Features for 3G3MV Series (Software Version 0028 (3.7 kW or
Less) or Higher)
D Operation Continuation Timer Added to the Momentary Power Interruption
Compensation Parameter (n081)
Parameter n081 can be set so that operation will not restart after a power interruption until the RUN
signal is ON for the time specified for the parameter (5 to 100 x 0.1 s). If the parameter is set to 2 (Inverter
restarts when power is restored), operation will recover for all Inverters at the same time, meaning the
power supply capacity must be sufficient for the maximum current. By setting timers to between 0.5 and
10.0 s, differences can be created in the Inverter recovery time to prevent tripping the power supply
breaker, which could happen if all Inverters recovered at the same time.
D Enter Command (Saving Parameters to EEPROM) Operation Selection (n170) To
Enable the Enter Command at Any Time
Previously, operation had to be stopped to use the Enter command to saved changes made to parameters during operation using DeviceNet or RS-422/485 communications. This sometimes caused saving
parameters to be forgotten when a system could not be stopped immediately after changing parameters, causing the need to reset the parameters again when they were lost at the next power interruption
or system shutdown. The new parameter n170 can be set to 1 to enable using the Enter command to
write parameters to EEPROM even during operation.
