Specification

The Omron 3G3RX-A4220-E1F is a versatile AC drive engineered for industrial environments requiring reliable speed and torque control. Part of the RX series, this 22 kW model supports three-phase 380-480V AC input and is equipped with a built-in EMC filter for reduced electromagnetic interference. Its sensorless vector control algorithm provides exceptional low-speed torque, making it suitable for demanding loads such as mixers, crushers, and extruders. The drive features a rugged design with conformal-coated PCBs for harsh conditions, and its integrated PLC function allows for basic logic control without external controllers. With Modbus RTU as standard, the 3G3RX-A4220-E1F easily integrates into existing automation networks, while optional fieldbus modules (Profibus, DeviceNet, EtherCAT) expand connectivity.
