3G3RX is an advanced general-purpose variable frequency drive from Omron with RoHS and other international standard certifications. It uses PWM control to suppress surge voltages, prevents interference with peripheral devices, has an automatic energy-saving function, is easy to operate, has a reliable emergency stop function, and a removable digital operation panel and control wiring board for easy maintenance and inspection. Long life design extends product life.
The 3G3RX series is an advanced general‑purpose variable frequency drive with features such as PWM surge suppression, built‑in RF noise filtering, and automatic energy‑saving mode. It supports a wide power range and includes a detachable digital operation panel for easy parameter setting and monitoring.
The manual covers emergency‑stop hardware, PID process control, instant power‑restart handling, over‑current suppression, brake unit specifications, and detailed display codes for accessing all parameters. It also provides wiring information, part names, and safety guidelines for reliable operation. This manual is written in Chinese.
| Input Frequency | 50‑60 Hz |
|---|---|
| Output Frequency | 0.5‑400 Hz |
| Surge Voltage Suppression | Up to 1,250 V between motor terminals |
It uses a hardware‑based output shut‑off and a detachable control terminal board, allowing safe emergency stopping while keeping the drive wiring intact.
All models up to 22 kW include a built‑in brake unit; when a brake resistor is installed, it safely dissipates energy during rapid deceleration or sudden stops.
PID control allows the drive to regulate temperature, pressure, flow and other process variables for fans and pumps without needing an external controller.
