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.
