Operation and Adjustment Precautions

WARNING Turn ON the input power supply only after mounting the front cover, terminal covers,

!

bottom cover, Operator, and optional items. Not doing so may result in electrical
shock.

WARNING Do not remove the front cover, terminal covers, bottom cover, Operator, or optional

!

items while the power is being supplied. Not doing so may result in electrical shock or
damage to the product.

!

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.

H Installation Direction and Dimensions

• Install the Inverter under the following conditions.

Ambient operating temperature:
Panel-mounting models (conforming to IP20): –10 to 50°C (0.1- to 3.7-kW Inverters)
Closed wall-mounting models (conforming to NEMA1 and IP20):

–10 to 40°C (5.5- to 7.5-kW Inverters)

Humidity: 95% max. (with no condensation)

Note 1. By removing the top and bottom covers from a 5.5- to 7.5-kW Inverter, it can be used as a

panel-mounting model (conforming to IP00) within an ambient temperature range of –10 to
50°C.

Note 2. All C-type Inverters (closed wall-mounting models: NEMA1-type for North America) are

closed wall-mounting models, and can be used within an ambient temperature range of –10 to
40°C. If the top and bottom covers are removed, the C-type Inverters can be used as panel­mounting models (conforming to IP00) within an ambient temperature range of –10 to 50°C.

• Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally

enclosed panel that is completely protected from floating dust.

• When installing or operating the Inverter, always take special care so that metal powder, oil, water, or

other foreign matter does not get into the Inverter.

• Do not install the Inverter on inflammable material such as wood.

• If a 5.5- to 7.5-kW Inverter or a C-type Inverter is to be installed inside of a control panel, it must have

the top and bottom covers removed and be used as a panel-mounting model (conforming to IP00).

2-6

H Ambient Temperature Control

• To enhance operation reliability, the Inverter should be installed in an environment free from extreme

temperature changes.

• If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner
to maintain the internal air temperature below 50°C.
The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air
temperature as low as possible.

• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temper­ature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment
and wires are easily influenced by heat.

H Protecting Inverter from Foreign Matter during Installation

• Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.

H Wiring on the Input Side of the Main Circuit

D Installing a Molded-case Circuit Breaker

Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded case
circuit breaker (MCCB) suitable to the Inverter.

• Install one wiring circuit breaker per Inverter.

• Choose an MCCB with the capacity indicated in the previous tables (Wire Size, Terminal Screw, Tight-

ening Torque, and Molded-case Circuit Breaker Capacities).

• For the MCCB’s time characteristics, be sure to consider the Inverter’s overload protection (one min-

ute at 150% of the rated output current).

• If the MCCB is to be used in common among multiple Inverters, or other devices, set up a sequence

such that the power supply will be turned OFF by a fault output, as shown in the following diagram.

Single-phase
200 V AC
3-phase 400 V AC

(See note.)

Fault output (NC)

Note Use a 400/200 V transformer for a 400-V model.

D Installing a Ground Fault Interrupter

Inverter outputs use high-speed switching, so high-frequency leakage current is generated.

In general, a leakage current of approximately 100 mA will occur for each Inverter (when the power
cable is 1 m) and approximately 5 mA for each additional meter of power cable.

Therefore, at the power supply input area, use a special-purpose breaker for Inverters, which detects
only the leakage current in the frequency range that is hazardous to humans and excludes high-fre­quency leakage current.

• For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity

amperage of at least 10 mA per Inverter.

• When using a general leakage breaker, choose a ground fault interrupter with a sensitivity amperage

of 200 mA or more per Inverter and with an operating time of 0.1 s or more.

2-24

Design Chapter 2

D Installing a Magnetic Contactor

If the power supply of the main circuit is to be shut off because of the sequence, a magnetic contactor
can be used instead of a molded-case circuit breaker.

When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly,
however, the regenerative braking does not work and the load coasts to a stop.

• A load can be started and stopped by opening and closing the magnetic contactor on the primary side.

Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break
down. To maintain the service life of the Inverter’s internal relays and electrolytic capacitors, it is rec­ommended that this operation be performed no more than once every 30 minutes.

• When the Inverter is operated with the Digital Operator, automatic operation cannot be performed

after recovery from a power interruption.

• When using the Braking Resistor Unit, be sure to arrange a sequence in which the thermal relay of the

Unit turns the magnetic contactor OFF.

D Connecting Input Power Supply to the Terminal Block

Input power supply can be connected to any terminal on the terminal block because the phase
sequence of input power supply is irrelevant to the phase sequence (R/L1, S/L2, and T/L3).

D Installing an AC Reactor

If the Inverter is connected to a large-capacity power transformer (660 kW or more) or the phase
advance capacitor is switched, an excessive peak current may flow through the input power circuit,
causing the converter unit to break down.

To prevent this, install an optional AC reactor on the input side of the Inverter.

This also improves the power factor on the power supply side.

D Installing a Surge Absorber

Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads
include magnetic contactors, electromagnetic relays, solenoid valves, solenoid, and magnetic brakes.

2-25

Design Chapter 2

D Installing a Noise Filter on the Power Supply Side

The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the
power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be
installed at the Power Supply to minimize this noise transmission. Conversely, noise can also be re­duced from the power line to the Inverter.

H Wiring on the Output Side of the Main Circuit

D Connecting the Terminal Block to the Load

Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U/T1, V/T2, and W/T3.

Check that the motor rotates forward with the forward command. Switch over any two of the output ter­minals to each other and reconnect if the motor rotates in reverse with the forward command.

D Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U/T1, V/T2, or W/T3.

If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged.

D Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the
Inverter casing, an electric shock or grounding will occur. This is extremely hazardous.

Also, be careful not to short the output wires.

D Do not Use a Phase Advancing Capacitor or Noise Filter

Never connect a phase advance capacitor or LC/RC Noise Filter to the output circuit.

Doing so will result in damage to the Inverter or cause other parts to burn.

D Do not Use an Electromagnetic Switch of Magnetic Contactor

Do not connect an electromagnetic switch of magnetic contactor to the output circuit.

If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent pro­tective circuit in the Inverter.

2-26

Design Chapter 2

D Installing a Thermal Relay

The Inverter has an electronic thermal protection function to protect the motor from overheating. If, how­ever, more than one motor is operated with one inverter or a multi-polar motor is used, always install a
thermal relay (THR) between the Inverter and the motor and set n037 to 2 (no thermal protection).

In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is
turned OFF by the contact of the thermal relay.

D Installing a Noise Filter on the Output Side

Connect a Noise Filter to the output side of the Inverter to reduce radio noise and induction noise.

D Countermeasures against Induction Noise

As described previously, a Noise Filter can be used to prevent induction noise from being generated on
the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction
noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction
noise.

D Countermeasures against Radio Interference

Radio noise is generated from the Inverter as well as the input and output lines. To reduce radio noise,
install Noise Filters on both input and output sides, and also install the Inverter in a totally enclosed steel
box.

The cable between the Inverter and the motor should be as short as possible.

D Cable Length between Inverter and Motor

As the cable length between the Inverter and the motor is increased, the floating capacity between the
Inverter outputs and the ground is increased proportionally. The increase in floating capacity at the In­verter outputs causes the high-frequency leakage current to increase, and this may adversely affect
peripheral devices and the current detector in the Inverter’s output section. To prevent this from occur­ring, use a cable of no more than 100 meters between the Inverter and the motor. If the cable must be
longer than 100 meters, take measures to reduce the floating capacity by not wiring in metallic ducts, by
using a separate cable for each phase, and so on.

Also adjust the carrier frequency (set in n80) according to the cable length between the Inverter and the
motor, as shown in the table below.

Cable length 50 m or less 100 m or less More than 100 m
Carrier frequency 10 kHz max. 5 kHz max. 2.5 kHz max.

D Single-phase Motors Cannot Be Used

The Inverter is not suited for the variable speed control of single-phase motors.

Single-phase motors are either capacitor start motors or split-phase start motors. (The method for de­termining rotation direction at startup is different.) If a capacitor start motor is used, the capacitor may be
damaged by a sudden electric discharge caused by Inverter output. If a split-phase start motor is used,
the starting coil may burn because the centrifugal switch does not operate.

2-28

Design Chapter 2

H Ground Wiring

• Always use the ground terminal of the 200-V Inverter with a ground resistance of 100 Ω or less. Simi­larly, always use the ground terminal of the 400-V Inverter with a ground resistance of 10 Ω or less.

• Do not share the ground wire with other devices such as welding machines or power tools.

• Always use a ground wire that complies with technical standards on electrical equipment and mini-

mize the length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode
and the ground terminal is too long, the potential on the ground terminal of the Inverter will become
unstable.

• When using more than one Inverter, be careful not to loop the ground wire.

H Countermeasures against Harmonics

With the continuing development of electronics, the generation of harmonics from indus­trial machines has been causing problems recently.
Refer to the following information for the definition of harmonics (i.e., harmonic currents
with voltages) and countermeasures against the generation of harmonics from the
Inverter.

D Harmonics

Definition

Harmonics consist of electric power produced from AC power and alternating at frequencies that are
integral multiples of the frequency of the AC power.

2-29

Design Chapter 2

The following frequencies are harmonics of a 60- or 50-Hz commercial power supply.
Second harmonic: 120 (100) Hz
Third harmonic: 180 (150) Hz

Second harmonic (120 Hz)

Basic frequency (60 Hz)

Third harmonic (180 Hz)

Problems Caused by Harmonics Generation

The waveform of the commercial power supply will be distorted if the commercial power supply contains
excessive harmonics. Machines with such a commercial power supply will malfunction or generate
excessive heat.

• Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC
power.
Such AC power, however, contains harmonics due to the difference in current flow between DC and
AC.

Obtaining DC from AC Using Rectifiers and Capacitors

DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and
smoothing the pulsating one-side voltage with capacitors. Such AC current, however, contains harmon­ics.

Design Chapter 2

Inverter

The Inverter as well as normal electric machines has an input current containing harmonics because
the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the
ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine.

D Countermeasures with Reactors against Harmonics Generation

DC/AC Reactors

The DC reactor and AC reactor suppress harmonics and currents that change suddenly and greatly.

The DC reactor suppresses harmonics better than the AC reactor. The DC reactor used with the AC
reactor suppresses harmonics more effectively.

The input power factor of the Inverter is improved by suppressing the harmonics of the input current of
the Inverter.

Connection

Connect the DC reactor to the internal DC power supply of the Inverter after shutting OFF the power
supply to the Inverter and making sure that the charge indicator of the Inverter turns OFF.

Do not touch the internal circuitry of the Inverter in operation, otherwise an electric shock or burn injury
may occur.

H Connecting the Braking Resistor and Braking Resistor Unit

When running a load with a large inertia or a vertical axis, regeneration energy will return to the Inverter.
If OV (overvoltage) is generated during deceleration, this indicates that the regeneration energy is
exceeding the capacity of the Inverter. In this case, use a Braking Resistor or a Braking Resistor Unit.

• Connect the Braking Resistor as shown in the following diagram.

Note 1. When using a Braking Resistor, install a thermal relay to monitor the temperature of the resis-

tor.

Note 2. When using a Braking Resistor or a Braking Resistor Unit, be sure to include a sequence

whereby the power supply for the Inverter will be turned OFF in the case of abnormal over­heating. Not doing so may result in burning.

S Braking Resistor: Use the output of the thermal relay used to monitor the temperature of the ther-

mometer.

S Braking Resistor Unit: Use the error contact output of the Braking Resistor Unit.

• When using a Braking Resistor, and Braking Resistor Unit be sure to set n092 (deceleration stall pre­vention selection) to “1” (without deceleration stall prevention).

D Wiring the Power Supply

Make sure that the Inverter and Noise Filter are grounded together.

• Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a dedicated
Noise Filter.

• Reduce the length of the ground wire as much as possible.

• Locate the Noise Filter as close as possible to the Inverter. Make sure that the cable length between

the Noise Filter and the Inverter does not exceed 40 cm.

• The following Noise Filters are available.

D Connecting a Motor to the Inverter

• When connecting a motor to the Inverter, be sure to use a cable with a braided shield.

• Reduce the length of the cable as short as possible and ground the shield on the Inverter side as well

as the motor side. Make sure that the cable length between the Inverter and the motor does not exceed
20 cm. Furthermore, it is recommended that a clamp core (Clamp Filter) be connected close to the
output terminals of the Inverter.

D Wiring a Control Cable

• Be sure to connect a cable with a braided shield to the control circuit terminals.

• Ground the shield on the Inverter side only.

D Grounding the Shield

In order to ground the shield securely, it is recommended that a cable clamp be directly connected to the
ground plate as shown below.

D Other noise countermeasures

• Use cable with a braided shield for inverter power supply lines, keep the cable as short as

possible, and connect the cable through an EMC-conforming input noise filter. Be sure to con­nect the shield to ground at both ends.

• Keep ground wires as short as possible. With a 400-V-class model, be sure to ground to a

neutral point on the power supply. This is also the time to ground the metal control panel (in­cluding doors).

• Use cable with a braided shield between the Inverter and motor as well. Keep the cable as

short as possible (20 m max.), and be sure to connect the shield to ground at both ends.
Mount a clamp filter near the Inverter output terminal for more effective noise suppression.

• Ground the shield with a conductive cable clamp directly to the ground plate.

• Wire the motor frame directly to ground, and connect the ground wire from the motor directly

to an EMC-conforming input noise filter.

• Improve shielding by using conductive packing in the doors of the control panel.

• Wireless devices and other equipment that generates electromagnetic waves should never

be installed in the same control panel with the Inverter.

• The DC power supply used for communications should have reinforced or double insulation.

• An Inverter control terminal has only basic insulation. More insulation is required if the termi-

nal is wired to parts people are likely to touch.

H Conforming to LVD

• Always connect the Inverter and power supply via a molded case circuit breaker
(MCCB) suitable to the Inverter for protecting the Inverter from damage that may result from short-cir­cuiting.

• Use one MCCB per Inverter.

• Select a suitable MCCB from the following table.

• With a 400-V-class Inverter, be sure to ground to a neutral point of the power supply.

Note To satisfy LVD requirements, the Inverter must be protected with a line breaker in case a short-cir-

cuiting accident occurs. When using a single line breaker to be shared with other Inverters or
devices, make sure that the Inverters and devices will be fully protected if there is a one-point
short-circuit, otherwise the Inverters and devices may be damaged.

The frequency reference power supply (FS) of the Inverter is of basic insulation construction. When
connecting the Inverter to peripheral devices, be sure to increase the degree of insulation.

3-2 Parameter Copy and Verify Function

The Digital Operator of the 3G3MV Inverter has an EEPROM in which the set values in
all the parameters and data on the capacity and software version of the Inverter can be
stored.
By using the EEPROM, most parameter set values in the Inverter can be copied to
another Inverter.

Note In the above case, however, the Inverters must have the same power supply spec-

ification and control mode (i.e., V/f or vector control mode). Some types of param­eter set values cannot be copied.

Note Before operating the Digital Operator, check that the FREQ adjuster is set to MIN.

H Connecting the System

• After confirming that the motor has stopped completely, connect the mechanical system.

• Be sure to tighten all the screws when fixing the motor axis in the mechanical system.

H Operation Using the Digital Operator

• In case a fault occurs during operation, make sure the Stop Key on the Digital Operator is easily acces-

sible.

• Use the Digital Operator in the same way as no-load operation.

• First set the frequency reference to a low speed of one tenth the normal operating speed.

H Checking the Operating Status

• Having checked that the operating direction is correct and that the machine is operating smoothly at

slow speed, increase the frequency reference.

• After changing the frequency reference or the rotation direction, check that there is no vibration or

abnormal sound from the motor. Check the monitor display (IOUT or multi-function monitor U-03) to
ensure that the output current is not becoming excessive.

Basic Operation

This section explains the basic settings required to operate and stop the Inverter.
The settings of parameters described here will be sufficient for simple Inverter opera­tions.
First make these basic settings and then skip to the explanations of those special func­tions, even when your application requires special functions, such as energy-saving
control, PID control, stall prevention, carrier frequency setting, overtorque detection,
torque compensation, slip compensation. Refer to Chapter 6 Advanced Operation.

5-1-2 Setting the Control Mode (n002)

• The 3G3MV Inverter operates in vector or V/f control mode to be selected according to the application.

• These two modes have the following characteristics.

Vector Control Mode

The Inverter in vector control mode calculates the vector of the operating condition of the motor. Then
the 150% rated output torque of the motor is provided at an output frequency of 1 Hz. Vector control
provides more powerful motor control than V/f control and makes it possible to suppress speed fluctua­tion regardless of changes in loads. Normally set the Inverter to this mode.

V/f Control Mode

This mode, which is used by conventional general-purpose inverters, is convenient when replacing a
conventional model with the 3G3MV Inverter because the Inverter in this mode can be operated without
considering the constants of the motor. Furthermore, set the Inverter to this mode if the Inverter is con­nected to more than one motor or special motors such as high-speed motors.

n002 before changing the control mode.

Note 2. Each of the following parameters is initialized according to the control mode set in this param-

eter. The default value varies with the control mode. Therefore, be sure to set the following
parameters after setting the control mode in n002.
