System position

TME identifies the exact reference as an Omron 3G3RX inverter with maximum motor power 22 kW, 3 x 380 V AC output, and 48 A current rating.

TME assigns the exact reference to the Omron 3G3RX series and provides an English RX inverter manual link.

The system path is inferred as the three-phase AC supply and drive commands, then 3G3RX-A4220-E1F, then the connected motor.

Unknown: installation compatibility, configuration, and unit condition are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: The Omron RX inverter regulates three-phase motor power from a variable-frequency drive control path.
System position: It intervenes between the three-phase AC supply and drive commands and the connected motor in the documented system path.
Upstream / inputs: Inputs or upstream: the three-phase AC supply and drive commands.
Downstream / outputs: Outputs or downstream: the connected motor.
Limitations: Unknown: installation compatibility, configuration, and unit condition are not established by the captured sources.

Inferences

Inferred system position: 3G3RX-A4220-E1F intervenes between the three-phase AC supply and drive commands and the connected motor.
Confidence: medium
Rationale: The exact-reference sources identify the component function and its connected interfaces; the intervening system position is an inference from those facts.
