Overview
International Standards Models (EC Directives and UL/cUL Standards)
The 3G3
R
X Inverter meets the EC Directives and UL/cUL standard requirements for worldwide use.
Human-/Environment-friendly, High-performance, General-purpose
Inverters Suitable for Various Advanced Applications
High Performance
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.
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 space-
saving 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.
