Safety Precautions
CAUTION
Do not connect resistors to the terminals (PD/+1, P/+, N/-) directly. Doing so might result in a smallscale 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.
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 this product.
Doing so may result in an injury.

Inverters Suitable for Various Advanced Applications
High Performance
High Starting Torque
With the vector control and auto-tuning functions, the RX Series has achieved high starting torque
in excess of 200% at 0.3 Hz.

Overview
Trip Suppression
This Inverter features two trip suppression functions: "Overcurrent trip suppression function" to
suppress overcurrent trip during acceleration, and "Overvoltage suppression function during
deceleration" to suppress overvoltage trip during deceleration. Therefore, the RX Series provides
tough operational capabilities regardless of the severe time setting of acceleration and deceleration.
Various Applications
Sensor-less Vector Control at 0 Hz
The RX Series provides sensor-less vector control, which is useful for up/down applications. It can
provide a high torque of 150%, even at a speed reference of 0 Hz (150% torque is available when
the Inverter capacity is increased by one rank). This function contributes to simplification of control
programs and extension of the service life of the brake.
Emergency Shutoff Function
By switching the dedicated switch (SW1) this function enables you to change the multi-function
input (input 3) to the emergency shutoff input. You can directly turn off a motor control power module
without operating the software. This function simplifies construction of safety applications.
Built-in Braking Circuit (up to 22 kW)
The Inverter models with 22 kW or lower capacity incorporate a braking transistor, enabling spacesaving configuration for applications that need rapid acceleration and stop.
Restart Speed Search Function
For a free-running motor (e.g. a fan motor), this function checks the direction of rotation and
frequency, enabling smooth restart of the motor.
High-torque Multi-operation
The RX Series enables balanced torque control for the whole system, in proportion to multiple motor
loads.
Deceleration Stop During Power Failure
During a power failure or momentary power interruption, the RX Series can decelerate and stop a
motor by using the motor braking energy.

the multi-function input terminal of the hardware circuit without going through the CPU software.
* This function stops switching of the main element.The circuit is not electrically turned off. While the
power supply is ON, do not touch the Inverter terminals and power cable (e.g. motor cable). Doing
so may result in electric shock, injury or ground fault.

•When this function is enabled, the multi-function input terminals 1 and 3 are exclusively used for
this function. No other function can be allocated to these terminals. If another function has been
allocated, it will automatically be disabled, and terminals 1 and 3 are changed to the emergency
shutoff terminals.
Function of multi-function input terminal 1
Reset signal (RS) / NO contact (Fixed)
This signal is used to reset the Inverter, and to reset the emergency shutoff trip [ E37.* ].
Function of multi-function input terminal 3
Emergency shutoff signal (EMR) / NC contact (Fixed)
This signal is used to turn off the Inverter output without using the built-in CPU.
With this signal input, the Inverter activates an emergency shutoff trip [ E37. * ].
* If multi-function input terminal 3 has not been connected or disconnected, or if the signal logic is
not matched, the Inverter activates an emergency shutoff trip [E37. *]. After checking the cable
connection and the signal logic, input the reset signal (RS).
Emergency shutoff trip [ E37. * ] can be reset only by the reset signal (RS) via multi-function input
terminal 1. (It cannot be reset with the Digital Operator.)
•To enable this function, set the slide switch SW1 lever in the Inverter to [ON].
(With the factory default setting, slide switch SW1 is [OFF]. [This function is disabled.])

1 before switch SW1 is set to "ON", the input terminal selection for the relevant terminal will be
automatically changed to "no (no allocation)" by setting SW1 to "ON". This is done in order to
prevent duplicated allocation of this function. Then, even if SW1 is reset to [OFF], the initial
allocation cannot be restored. The User should Re-allocate the terminal function.
Example) When the multi-function input terminal 2 [C002] is [18 (RS)], setting SW1 to [ON] changes
the [C002] setting to [no (no allocation)]. [18 (RS)] will be allocated to the multi-function
input terminal 1 [C001].
Then, even if SW1 is reset to [OFF], the multi-function input terminal 2 [C002] setting is [no (no

Wiring the Main Circuit Terminals
Main Power Supply Input Terminals (R/L1, S/L2, T/L3)
• Use an earth leakage breaker for circuit (wiring) protection between the power supply and the
main power supply terminals (R/L1, S/L2, T/L3).
• An earth leakage breaker may malfunction due to the effect of high frequency. Use an earth
leakage breaker with a large high-frequency sensitivity current rating.
• If the Inverter protection function is activated, a malfunction or accident may have occurred to your
system. Connect a magnetic contactor to turn off the Inverter power supply.
• Do not start or stop the Inverter by switching ON/OFF the magnetic contactor connected on the
Inverter power supply input (primary) side and output (secondary) side.
To start or stop the Inverter via an external signal, use the operation command (FW or RV) on the
control circuit terminal block.
• This Inverter uses a 3-phase power supply. A single-phase power supply cannot be used.
• Do not use this Inverter with a phase loss power input. Doing so may damage the Inverter.
By factory default, the phase loss input protection is disabled. If a phase of power supply input is
interrupted, the Inverter reverts to the following status:
R/L1-phase or T/L3-phase is interrupted:
S/L2-phase is interrupted:The Inverter reverts to single-phase operation, causing a
The Inverter does not operate.
trip (due to undervoltage, overcurrent, etc.) or damage to
the Inverter.
Even if the power input is under a phase loss condition, the internal capacitor is charged with
voltage, causing an electric shock or injury.
When changing the cable connections, refer to the instructions on page 2-1.
2-12
Page 38
2-2 Wiring
• In the following cases, the internal converter module may be damaged. Use caution to avoid
them:
Imbalance of power supply voltage is 3% or more.
Power supply capacity is ten times or more than the Inverter capacity, and also 500 kVA or more.
Rapid change in power supply voltage.
2
Design
Example) When several Inverters are connected with a short bus.
When the phase advance capacitor is turned on/off.
• Do not turn power on/off more than once every 3 minutes.
Doing so may damage the Inverter.
Inverter Output Terminals (U/T1, V/T2, W/T3)
• For connection of the output terminal, use the applicable cable or a cable with a larger diameter.
Otherwise, the output voltage between the Inverter and the motor may drop.
Particularly during low-frequency output, a voltage drop occurs with the cable, resulting in motor
torque reduction.
• Do not mount a phase advance capacitor or surge absorber. These devices cause the Inverter to
trip, or may cause damage to the capacitor or surge absorber.
• If the cable length exceeds 20 m (particularly, with 400-V class), a surge voltage may be
generated at the motor terminal due to stray capacitance or inductance of the cable, causing the
motor to burn out.
• To connect several motors, provide a thermal relay for each.
• The RC value of each thermal relay should be 1.1 times of the motor rated current. The relay may
trip easily depending on the cable length. In this case, connect an AC reactor to the Inverter
output.
DC Reactor Connection Terminal (PD/+1, P/+)
• This terminal is used to connect the optional DC reactor for power factor improvement.
By factory default, a short-circuit bar has been connected between the terminals PD/+1 and P/+.
Before connecting the DC reactor, remove this short-circuit bar.
• The length of the DC reactor connection cable should be 5 m or less.
If the DC reactor is not used, do not remove the short-circuit bar.
If you remove the short-circuit bar without connecting the DC reactor, no power is supplied to
the Inverter main circuit, disabling operation.
• The Inverters with 22 kW or lower capacity incorporate a regenerative braking circuit.
To improve braking capability, mount the optional external braking resistor to this terminal.
Do not mount a resistor whose resistance is lower than the specified value. Doing so may damage
the regenerative braking circuit.
• The Inverters with 30 kW or higher capacity do not incorporate a regenerative braking circuit.
To improve braking capability, the optional regenerative braking unit and braking resistor are
required. In this case, connect the regenerative braking unit terminals (+, -) to the Inverter
terminals (P/+, N/-).
• The cable length should be 5 m or less. Twist the two wires.
• Do not connect any device other than the optional regenerative braking unit or external braking
resistor to this terminal.
2-13
Page 39
Ground Terminal (G)
• To prevent electric shock, be sure to ground the Inverter and the motor.
• According to the Electric Apparatus Engineering Regulations, the 200-V class Inverter should be
connected to the grounding electrodes under type-D grounding conditions (conventional type 3
grounding: ground resistance 100 or less), the 400-V class Inverter should be connected to the
grounding electrodes under type-C grounding conditions (conventional special type 3 grounding:
ground resistance 10 or less).
• For the ground cable, use the applicable cable or a cable with a larger diameter. Make the cable
length as short as possible.
• When several Inverters are connected, the ground cable must not be connected across several
Inverters, and must not be looped.
Otherwise, the Inverters may malfunction.

Connection for Separating Inverter Control Circuit Power Supply from Main Power Supply
If the Inverter protection circuit is activated to turn off the magnetic contactor of the Inverter input
power supply, the power to the Inverter control circuit is also turned off, and the alarm signal cannot
be kept on.
If the alarm signal must be kept on, use control circuit power supply terminals Ro and To.
Connect control circuit power supply terminals Ro and To to the primary circuit of the magnetic
contactor according to the following procedure.

* To separate the control circuit power supply (Ro, To) from the main circuit power supply (R/L1, S/
L2, T/L3), observe the following instructions:
• For wiring between terminals Ro and To (terminal screw size: M4), use a cable of 1.25 mm
or more.
• Connect a 3 A fuse to the control circuit power supply cable.
• If the control circuit power supply (Ro, To) is turned on before the main circuit power supply
(R/L1, S/L2, T/L3), ground fault detection at power-on is disabled.
• To use a DC power supply for the control circuit power supply (Ro, To), set the multi-function
output terminal contact selection (C031 to C036) for the multi-function output terminals (11 to
15) and relay output terminals (AL2, AL1, AL0) to "00". If the multi-function output terminal
contact selection is set to "01", the output signal may chatter when the DC power supply is

Wiring Control Circuit Terminals
• Terminals L and PLC are insulated from each other via the input and output signal common
terminals.
Do not short-circuit or ground these common terminals.
Do not ground these common terminals via external equipment. (Check the external equipment
ground conditions.)
• For wiring the control circuit terminals, use twisted shielded cables (recommended size: 0.75
2
mm
), and connect the shielded cable to each common terminal.
• The control circuit terminal connection cables should be 20 m or less.
• Separate the control circuit terminal connection cables from the main circuit cable (power cable)
and the relay control circuit cable.
• For the connection of the TH (thermistor input) terminal, twist cables with the terminal PLC
individually, and separate them from other PLC common cables.
Since a weak current flows through the thermistor, the thermistor connection cable must be
separated from the main circuit cable (power cable). The thermistor connection cable should be
20 m or less.
TH FW8 CM15
PLC CM1 7
• To use a relay for the multi-function output terminal, connect a surge-absorbing diode in parallel
with the coil.
• Do not short-circuit the analog power supply terminals (between H and L) and/or the interface
power supply terminals (between P24 and PLC).
Doing so may result in failure of the Inverter.

Arrangement of the Control Circuit Terminal Block
By factory default the terminal FW and the multi-function input terminal are set to sink logic (NPN).
To change the input control logic to source logic (PNP), remove the short-circuit bar between the

Wiring the Digital Operator
• The RX Series Inverter can be operated with the optional 3G3AX-OP01/OP05 as well as the
standard Digital Operator.
• To use the Digital Operator apart from the Inverter body, place an order for the optional cable

• The optional cable should be 3 m or less. Using a cable longer than 3 m may cause malfunction.
Conforming to EC Directives
Conforming Standards
•EMC directiveEN 61800-3: 2004
•Low-voltage directiveEN 61800-5-1: 2003
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 RX 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
•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 shield braided cables.
•Keep the cables as short as possible.
Low-voltage Directive
The RX models have conformed to the EMC directive EN61800-5-1 by performing the machine installation and wiring as shown below.
•The RX 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.

WARNING
CAUTION
Operation
3Operation
Do not change wiring and slide switches (SW1), put on or take off Digital Operator and optional
devices, replace cooling fans while the input power is being supplied. Doing so may result in a
serious injury due to an electric shock.
Do not remove the terminal block cover during the power supply and 10 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 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.
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.
3-1
Page 51
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.
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 with the main power supply applied, if a signal voltage is erroneously applied to the
control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.

3-1Operation Method
This Inverter has the following operation methods that are selected by the RUN command/
frequency reference settings.
The features and the requirements for each operation method are also given below:
3
Operation
To enter the RUN command/frequency reference via the Digital Operator
This action operates the Inverter via a key sequence of the standard or optional Digital Operator.
When operating the Inverter only via the Digital Operator, the Inverter does not need to be
connected to the control circuit terminal block.
Digital Operator
To enter the RUN command/frequency reference from the control circuit terminal block
This action operates the Inverter by connecting the external signals (from the frequency setting
device, starting switch, etc.) to the control circuit terminal block.
The operation starts by turning ON the RUN command (FW, RV) while the input power supply is
turned ON.
Note: that the frequency can be set using a voltage signal or a current signal from the control circuit
terminal block, which can be selected according to the system. For details, refer to "Control Circuit
Terminal" (page 2-7).
(Requirements for operation)
• RUN command: Switch, Relay etc.
• Frequency reference: External signal (e.g. 0 to 10 V DC, -10 to 10 V DC, 4 to 20 mA)
