Indications and Meanings of Safety Information

In this user's manual, the following precautions and signal words are used to provide information to ensure the
safe use of the 3G3JX Inverter.
The information provided here is vital to safety. Strictly observe the precautions provided.

Meanings of Signal Words

Indicates an imminently hazardous situation which, if not avoided,

WARNING

CAUTION

Alert Symbols in This Document

is likely to result in serious injury or may result in death. Additionally
there may be severe property damage.

Indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury or in property damage.

WARNING

Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury
due to an electric shock.

Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious
injury due to an electric shock.

Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or
fire.
(200-V class: type-D grounding, 400-V class: type-C grounding)

Do not remove the front cover during the power supply and 5 minutes after the power shutoff. Doing
so may result in a serious injury due to an electric shock.

Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious
injury due to an electric shock.

Inspection of the Inverter must be conducted after the power supply has been turned off. Not doing
so may result in a serious injury due to an electric shock.
The main power supply is not necessarily shut off even if the emergency shutoff function is
activated.

Do not change wiring, mode change switches (S7, S8), optional devices or replace cooli ng fans
while the input power is being supplied.
Doing so may result in a serious injury due to an electric shock.

5

Safety Precautions

Do not connect resistors to the terminals (+1, P/+2, N/-) directly.
Doing so might result in a small-scale fire, heat generation or damage to the unit.

Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding
brake is not a stop motion device designed to ensure safety.)

Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking
resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might
result in a moderate burn due to the heat generated in the braking resistor/regenerative braking
unit. Configure a sequence that enables the Inverter power to turn off when unusual overheating is
detected in the braking resistor/regenerative braking unit.

The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or
other property. Place covers on the openings or take other precautions to make sure that no metal
objects such as cutting bits or lead wire scraps go inside when installing and wiring.

Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the
power supply and for some time after the power shutoff. Doing so may result in a burn.

CAUTION

Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches
the Inverter capacity on the power supply side. Not doing so might result in damage to property due
to the short circuit of the load.

Do not dismantle, repair or modify the product.
Doing so may result in an injury.

Wiring the Main Circuit Terminals (Input Side)

Installing a Molded-case Circuit Breaker (MCCB)

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

•Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an MCCB,
according to the Inverter capacity.

•Install one MCCB per Inverter.

•Choose an appropriate MCCB capacity according to the fuse size on page 2-13.

•When choosing MCCB's time characteristics, be sure to consider the Inverter's overload protection
(1 minute at 150% of the rated output current).

•By programming the sequence as illustrated below, you can turn off the power via the relay outputs
(MA, MB, and MC) for the 3G3JX Series.

Installing a Ground Fault Interrupter

•The Inverter's output uses high-speed switching, and so generates high-frequency current
leakage. (Generally, if the power cable is 1 m, the leakage current is approx. 100 mA per Inverter,
and approx. 5 mA is added per additional meter of the power cable.)

•At the power supply input part, install a special-purpose ground fault interrupter for Inverters that
excludes high-frequency leakage current and detects only the leakage current within a frequency
range that is hazardous to humans. (Choose a ground fault interrupter with a sensitivity current of
at least 10 mA per Inverter.)

•Alternatively, use a general ground fault interrupter with a sensitivity current of 200 mA or more per
Inverter, and with an operating time of 0.1 s or more.

2-16

2-2 Wiring

Installing a Magnetic Contactor (MC)

•If the power supply of the main circuit is shut off due to sequencing, a magnetic contactor (MC) can
be used. (When forcibly stopping the load with an MC on the primary side of the main circuit,
however, the regenerative braking does not work and the load coasts to a stop (free run).)

•Frequently opening and closing the magnetic contactor (MC) to start and stop a load may cause

2

Connection Sequence to the Terminal Block

the Inverter to break down. To extend the life of the Inverter's internal electrolytic capacitor, limit
the frequency to no more than once every 30 minutes.

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

Design

Installing an AC Reactor

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

•Install an optional AC reactor on the input side of the Inverter. An AC reactor will also improve the
power factor of the power input side.

Installing a Surge Absorber

•Always use a surge absorber or diode when magnetic contactors (MC), electromagnetic relays,
solenoid valves, solenoid, and magnetic brakes are used.

Connecting a Regenerative Braking Unit

When running a load with a large inertia or a vertical axis, regenerative energy will return to the
Inverter.
If overvoltage in the main circuit is generated during deceleration, this indicates that the
regenerative energy exceeds the capacity of the Inverter. In this case, use a regenerative braking
unit.
Select a regenerative braking unit referring to the allowable operation cycle of the regenerative
braking unit specifications regardless of the Inverter capacity.
When using a braking resistor with the resistor of a regenerative braking unit removed, refer to the
connectable resistance of the regenerative braking unit and the allowable braking frequency of the
braking resistor in making a selection.
Refer to “ 7-5 Options” (page 7-14 to 16) for further information when making a selection.

2-17

r

•When using a regenerative braking unit, be sure to include a sequence whereby the power supply
for the Inverter will be turned off in the event of abnormal overheating. Not doing so may result in
fire.

Installing a Noise Filter on the Input Side

•The Inverter's output uses high-speed switching, so noise may be transmitted from the Inverter to
the power line, affecting peripheral devices.

•It is recommended that a noise filter be installed on the input side to minimize noise transmission.
(Installing a noise filter on the input side can also reduce the noise from the power line to the
Inverter.)

Wiring the Main Circuit Terminals (Output Side)

* Use a noise filter designed for Inverters. A general-purpose noise filter will be less effective and

may not reduce noise.

Connect the Terminal Block to the Load

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

•Check that the motor rotates forward with the forward command. Switch over any two of the output
terminals (U/T1, V/T2, W/T3) and reconnect if the motor rotates in reverse to the forward
command.

Never Connect a Power Supply to the Output Terminals

•If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged.
Never connect a power supply to output terminals U/T1, V/T2, or W/T3.

2-19

Never Short-circuit or Ground the Output Terminals

•Never touch the output terminals by hand.

•If the output wires come into contact with metal materials, an electric shock or ground fault will
occur. This is extremely hazardous. Be careful not to short-circuit the output wires.

2-2 Wiring

Do Not Use a Phase Advance Capacitor or Noise Filter

•Doing so may result in damage to the Inverter or cause the parts to burn. Never connect a phase
advance capacitor or LC/RC noise filter to the output circuit.

Do Not Use an Electromagnetic Switch

•If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent
protective circuit in the Inverter. Do not connect an electromagnetic switch or magnetic contactor
(MC) to the output circuit.

Cable Length Between Inverter and Motor

Use a cable of 50 m or less between the Inverter and the motor. If the cable length is increased, the
stray capacitance between the Inverter outputs and the ground is increased proportionally. An
increase in stray capacitance causes high-frequency leakage current to increase, affecting the
current detector in the Inverter's output unit and peripheral devices. If your system configuration
requires a cable length of 50 m or more, perform the following:

•Wire in metallic ducts.

•Use separate cables for each phase.

•Set the Inverter to a lower carrier frequency (b083).

Do Not Use Single-phase Motors

•A single-phase motor uses the capacitor start method or split-phase start method to determine its
rotation direction at startup, and thus is not suitable for the variable speed control via the Inverter.
Do not use single-phase motors.

* If a capacitor start motor is used, the capacitor may be damaged by a sudden electric charge and

discharge caused by Inverter output. If a split-phase start motor is used, the startup coil may burn
because the centrifugal switch does not operate.

Conforming to EC Directives

Conforming Standards

•EMC directive EN 61800-3

•Low-voltage directive EN 61800-5-1

Concept of Conformity

EMC Directive

OMRON products are the electrical devices incorporated and used in various machines or
manufacturing equipment. For this reason, we make efforts to conform our products to their related
EMC standards so that the machines or equipment which have incorporated our products should
easily conform to the EMC standards. The 3G3JX models have conformed to the EMC directive EN
61800-3 by following the installation and wiring method as shown below. Your machines or
equipment, however, vary in type, and in addition, EMC performance depends on the configuration,
wiring, or location of the devices or control panels which incorporate the EC directive conforming
products. This in turn does not allow us to confirm the condition and the conformity in which our
products are used. Therefore, we appreciate confirmation of the final EMC conformity for the whole
machine or equipment on your own.

Wiring the Power Supply

•Be sure to connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an EMC
conforming dedicated noise filter 3G3AX-EFI.

•Keep the ground cable as short as possible.

•Keep the cable between the Inverter and the noise filter as short as possible.

Connecting a Motor to the Inverter

•When connecting a motor to the Inverter, be sure to use shielded braided cables.

•Keep the cables as short as possible.

Low-voltage Directive

The 3G3JX models have conformed to the EMC directive EN61800-5-1 by performing the machine
installation and wiring as shown below.

•The 3G3JX models are an open type device. Be sure to install it inside the control panel.

•The power supply and voltage (SELV) with reinforced or double insulation should be used for
wiring to the control circuit terminals.

•To satisfy requirements of the LVD (low-voltage) directive, the Inverter must be protected with a
molded case circuit breaker (MCCB) in case a short-circuiting accident occurs. Be sure to install a
molded case circuit breaker (MCCB) on the power supply side of the Inverter.

•Use one molded case circuit breaker (MCCB) per Inverter.

•Use the crimp-type terminal with an insulation sleeve to connect to the main circuit terminals.

•When not using the braking resistor or braking resistor unit, connect the crimp-type terminal with
an insulation sleeve to the braking resistor connection terminals (P/+2, N/-).

WARNING

Do not remove the front cover during the power supply and 5 minutes after the power shutoff.
Doing so may result in a serious injury due to an electric shock.

3

Operation

Do not operate the Digital Operator or switches with wet hands. Doing so may result in a serious
injury due to an electric shock.

Inspection of the Inverter must be conducted after the power supply has been turned off. Not doing
so may result in a serious injury due to an electric shock.
The main power supply is not necessarily shut off even if the emergency shutoff function is activated.

Do not change wiring, mode change switches (S7, S8), optional devices or replace cooling fans while
the input power is being supplied.
Doing so may result in a serious injury due to an electric shock.

CAUTION

Do not touch the Inverter fins, braking resistors and the motor, which become too hot during the
power supply and for some time after the power sh utoff. Doing so may result in a burn.

Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the
Inverter capacity on the power supply side. Not doing so might result in damage to property due to
the short circuit of the load.

Safety Information

Operation and Adjustment

•Be sure to confirm the permissible range of motors and machines before operation because the Inverter
speed can be changed easily from low to high.

•Provide a separate holding brake if necessary.

Precautions for Use

Error Retry Function

•Do not come close to the machine when using the error retry function because the machine may abruptly
start when stopped by an alarm.

•Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may
abruptly start.

Non-Stop Function at Momentary Power Interruption

•Do not come close to the machine when selecting restart in the non-stop function at momentary power
interruption selection (b050) because the machine may abruptly start after the power is turned on.

3-1

Operation Stop Command

•Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when
function settings are performed.

•When checking a signal during the power supply and the voltage is erroneously applied to the control input
terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.

•Helps remove noise in the frequency setting circuit.

•Set a larger data value if stable operation cannot be secured because of noise.
Note that the larger the data value is, the slower the response time.

•In case of setting "17", it indicates the setting of 16 moving average calculation disregarding the
voltage fluctuation equivalent to 0.1 Hz. Though the frequency becomes less likely to fluctuate, the
resolution for analog input decreases. This setting is not suitable for equipment that requires rapid
response.

Set different RUN speeds by using codes and switch the set speed via the terminal.

Torque Boost

This function helps compensate for insufficient motor torque in a low speed range.

•Compensates for the voltage drop caused by the primary resistance of the motor or by wiring to
suppress torque reduction in a low speed range.

•To select the simple torque boost in the torque boost selection (A041/A241), set the motor capacity
selection (H003/H203) and motor pole number selection (H004/H204) according to your motor.

Manual Torque Boost [A042/A242, A043/A243]

•Adds the voltage set in A042/A242 and A043/A243 to the V/f characteristics, and outputs the
resulting voltage. The addition value is set in percentage terms based on the AVR voltage selection
(A082) as 100%.

•The manual torque boost frequency (A043/A243) is set in percentage terms based on the base
frequency as 100%.

•If you raise the set value of the manual torque boost, be careful about motor overexcitation.
Otherwise, the motor may burn out.

•Should such a situation occur, lower the set value of A042/A242.

Simple Torque Boost [A041/A241]

•If simple torque boost is selected in the torque boost selection (A041/A241: 01), it operates to
adjust the output voltage depending on the load level.

•To select simple torque boost in the torque boost selection (A041/A241), set the motor capacity
selection (H003/H203) and motor pole number selection (H004/H204) correctly according to your
motor.

•You may avoid a possible overcurrent trip during deceleration by always setting the AVR selection
to ON (A081: 00).

•Sufficient characteristics may not be obtained if you select two or more lower rank motor size than
specified.

•Two methods are available for DC injection braking: One is the external method via the multi­function input (external DC injection braking); the other is the internal method performed
automatically to stop the motor (internal DC injection braking).

•Below are operation types:

Edge operation: DB operates during the specified time period from the DB signal input.
Level operation: DB operates while a signal is being input.
Frequency control mode: DB operates when the frequency reaches the specified level during
operation.

•If DC injection braking operates at a high motor speed, an overcurrent trip (E01 to E04) or overload
trip (E05) may occur. For internal DC injection braking, the following adjustment may help you
avoid such a situation:

Lower the DC injection braking frequency (A052).
Increase the DC injection braking delay time (A053)

For external DC injection braking via the multi-function input, use the external DC injection braking
terminal (along with deceleration stop).

External DC Injection Braking (A051 = 00)

•Allocate 07 (DB) to the desired multi-function input. DC injection braking can be applied by turning
on/off the DB terminal, regardless of the DC injection braking selection (A051).

•Set the DC injection braking power in A054.

•If the DC injection braking delay time (A053) is set, the Inverter output will be shut off during the
specified time period and the motor goes into free-run status. After the set time elapses, DC
injection braking starts.

•Set the DC injection braking time (A055) via the Digital Operator or the DB terminal while taking
into account motor heat generation. Long continuous use of DB may cause the motor to burn out.

•Perform each setting according to your system after selecting the level or edge operation in A056.
