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.

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

1-1 Functions

High-torque Multi-operation

The 3G3RX 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 3G3RX Series can decelerate and stop a motor by using the motor braking energy.

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.

2-1 Installation

Backing Plate

 Inverter with 22 kW or Lower Capacity

When running cables, cut the points between the backing plate and unnecessary portions with nippers or a wire cutter, and remove.

 Inverter with 30 kW or Higher Capacity

For Connection Without Cable Conduit

Make a cut in the rubber bushing of the backing plate with nippers or a wire cutter, and insert a cable.

For Connection With Cable Conduit

Remove the rubber bushing from the conduit connecting portions, and connect the cable conduit.

* Do not remove the rubber bushing unless you connect a cable conduit.

Otherwise, the cable sheath may be damaged by the inner edge of the backing plate, resulting in short-circuit or ground fault.

+10 V DC power supply for the FV terminal. Allowable load current:

20 mA max.

With a 0 to 10 V DC voltage input, the frequency reaches the maximum at 10 V. Set at A014 if the maximum frequency needs to be achieved at lower than 10 V.

With a 0 to ±10 V DC voltage input, the FE signal is added to the frequency reference signal of the FV or FI terminal. By changing the setting, the frequency reference can be input even with the FE terminal independently.

With a 4 to 20 mA DC current input, the maximum frequency is set at 20 mA. The FI signal is only active when the AT terminal is ON. Allocate the AT function to the multifunction input terminal.

Input impedance 10 kΩ Allowable input voltage range:
