Safety Precautions

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 3G3RX 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, 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.

Alert Symbols in this Document

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.

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.

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 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.

Page 8

Safety Precautions

CAUTION

Do not connect resistors to the terminals (+1, P/+2, 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.

High Starting Torque

With the vector control and auto-tuning functions, the 3G3RX 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 3G3RX 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 3G3RX 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

Switching the internal slide switch (SW1) changes the multi-function input terminal (S3) to the emergency shutoff input. The power module that controls the motor is shutoff directly without operating software.

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.

1-2

Page 20

1-1 Functions

2-1 Installation

Installation Environment

•Increased ambient temperatures will shorten the life of the Inverter.

•Keep the Inverter away from heating elements (such as a braking resistor, DC reactor, etc.). If the Inverter is installed in an enclosure, keep the ambient temperature within the range of the specifications, taking dimensions and ventilation into consideration.

•When several 3G3RX models are installed in an enclosure and a ventilation fan is mounted in the enclosure, be careful about the layout of the Inverters and the air intake apertures. Depending on the internal layout of the panel, the Inverter's cooling effect may deteriorate, resulting in an increase in ambient temperature. Also, use thorough caution in making sure that the Inverter's ambient temperature is within the allowable operating temperature range.

•Before installing the Inverter, place a cover over all the ventilation openings to shield them from foreign objects. After completing the installation process, be sure to remove the covers from the Inverter before operation.

•Below is the heat radiation according to the Inverter capacity.

Slide Switch (SW1) Settings

The built-in slide switch is used to enable or disable the emergency shutoff function. (Factory Default: Disabled) * For the location of the slide switch, refer to (page 2-12).

Emergency Shutoff Function (Factory Default: Disabled)

•This function is intended to turn off the Inverter output (stop switching the main element) via only 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 S1 and S3 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 S1 and S3 are changed to the emergency shutoff terminals.

Function of multi-function input terminal S1

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 S3

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. * ].

2-10

Page 34

2-2 Wiring

* If multi-function input terminal S3 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 S1. (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.])

* Before operating slide switch SW1, make sure that the input power supply is OFF.

*1. With the terminal with input terminal selection [18 (RS)], NO/NC selection is fixed to [00 (NO)]. *2. When [C003] is [64 (EMR)], [C013] is fixed to [01 (NC)]. *3. If [18 (RS)] has been allocated to a multi-function input terminal (except for S3) other than S1

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. Re-allocate the terminal function.

Example) When the multi-function input terminal S2 [C002] is [18 (RS)], setting SW1 to [ON]

changes the [C002] setting to [no (no allocation)]. [18 (RS)] will be allocated to the multifunction input terminal S1 [C001]. Then, even if SW1 is reset to [OFF], the multi-function input terminal S2 [C002] setting is [no (no allocation)], and the multi-function input terminal S1 [C001] setting is [18 (RS)].

*4. Input terminal selection [64 (EMR)] cannot be selected with the Digital Operator. When slide

switch SW1 is set to [ON], this function will be automatically allocated.

Page 35

*5. Once slide switch SW1 is set to [ON], allocation of multi-function input terminals S1 and S3 will

not be restored, even if SW1 is reset to [OFF] afterward. Re-allocate the terminal function.

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-phase or T-phase is interrupted: The Inverter does not operate. S-phase is interrupted: The Inverter reverts to single-phase operation, causing a

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 36

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.

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 (+1, P/+2)

• 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 +1 and P/+2. 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.

External Braking Resistor Connection Terminal (P/+2, RB)/Regenerative Braking

Unit Connection Terminal (P/+2, N/-)

• 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 (P/+2, N/-) to the Inverter terminals (P/+2, 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 37

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 Ω 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 Ω 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.

Installing Screws in the Main Circuit Terminal Block

• For the main circuit terminal blocks of 3G3RX-A2055/-A2075/-A4055/-A4075, be sure to install the terminal block screw washers with their grooved sides aligned vertically, as shown below. Not doing so may result in a contact failure or fire. (Intended terminals: R/L1, S/L2, T/L3, +1, P/+2, N/-, U/T1, V/T2, W/T3, RB)

Connection for Separating Inverter Control Circuit Power Supply from Main P ower 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, S, T),

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, S, T), 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 (P1 to P5) and relay output terminals (MA, MB, MC) 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 turned off.

• Tightening torque for terminals Ro and To M4: 1.2 N•m (1.4 max.)

Thermistor

PLC

• Terminals FC and SC 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

), 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 cable 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 SC

individually, and separate them from other SC 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.

2-2 Wiring

Design

• 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 FS and FC) and/or the interface

power supply terminals (between P24 and SC). Doing so may result in failure of the Inverter.

Wiring the Digital Operator

• The 3G3RX Series Inverter can be operated with the optional 3G3AX-OP01 as well as the standard Digital Operator.

• To use the Digital Operator apart from the Inverter body, place an order for the optional cable 3G3AX-OPCN1 (1 m), or 3G3AX-OPCN3 (3 m).

• 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 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 3G3RX 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.

Design

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 3G3RX models have conformed to the EMC directive EN61800-5-1 by performing the machine installation and wiring as shown below.

•The 3G3RX 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.
