Technical Specifications Internal drive interface, 10/100 Mbit/s Ethernet port. Operating power supplied by the main drive unit. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Supports multiple industrial Ethernet protocol stacks.
Functional Features Realizes protocol conversion between drive internal interface and external Ethernet network. Uploads drive running status, fault information and parameter values to host controller. Receives speed setting, start‑stop and parameter modification commands from upper system. On‑board LED indicators display module power‑on status, Ethernet link condition and fault alarm. Built‑in self‑diagnosis detects internal interface and Ethernet channel abnormalities.
Application Scenarios Spare Ethernet communication adapter for ABB industrial frequency converters. Used for drive networking renovation and cabinet maintenance projects.
Performance Parameters Stable high‑speed Ethernet data transmission performance. Accurate bidirectional protocol conversion capability. 
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. Protocol processing chip, Ethernet physical layer transceiver and signal conditioning circuit. Internal plug‑in connector and external RJ45 Ethernet port.
Structural Characteristics Compact plug‑in option module structure. One side is equipped with plug‑in connector for connecting to drive mainboard, the other side provides RJ45 network interface. Status indicator lamps are arranged on module surface.
Working Principle RETA‑02 obtains working power from the drive main control board. It reads internal operating data of the drive, converts data into Ethernet protocol telegram and sends it to upper‑level controller.
Installation Requirements Insert RETA‑02 into the designated option slot of drive control board and lock the buckle. Connect Ethernet network cable to RJ45 port. Restore drive power supply, configure IP address and related communication parameters, verify bidirectional data exchange between drive and upper‑level controller.
