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.

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.

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
EMC directive EN61800-3
Low-voltage directive EN50178
UL/cUL UL508C
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 Invert-
ers.
