ABB RDCU-02C (64607901E) Drive Control Unit

Product Description

The ABB RDCU-02C (P/N: 64607901E) is a fiber-optic drive control unit for ACS800 series inverters. It executes motor control algorithms, enables real-time data exchange via Profibus-DP/PROFINET, and provides system diagnostics. Fiber-optic isolation ensures noise immunity in high-voltage industrial environments .

Technical Parameters

Advantages & Features

1. Fiber-Optic Isolation

   • Electrically isolates control signals from EMI, critical for inverter cabinet applications .

2. Multi-Protocol Support

   • Profibus-DP master/slave mode and PROFINET real-time communication for PLC integration .

3. Hot-Swap & Diagnostics

   • Live module replacement; self-tests detect overcurrent/communication loss with LED/LCD alerts .

4. Dynamic Power Adaptation

   • Adjust power ratings (e.g., via parameter 11221) and restore firmware via DriveWindow backup (*.BGP) .

5. Compact Design

   • DIN-rail mounting, compatible with ACS800 inverters .

Application Fields

1. Manufacturing

   • Robotic servo control, CNC spindle speed regulation .

2. Energy Management

   • Wind turbine pitch control, hydroelectric turbine synchronization .

3. Process Industries

   • Chemical pump flow control, steel mill torque distribution .

4. Public Utilities

   • HVAC drives, wastewater pump optimization via MODBUS RTU .

5. Heavy Transport

   • Crane hoisting systems, mining conveyor speed control .

Precautions

1. Installation

   • Avoid parallel routing with power cables; fiber bend radius ≥50mm; ambient temp ≤50°C .

2. Configuration

   • Backup firmware before modifying power parameters (e.g., 11221); use DriveWindow for N697/N652 recovery .

3. Troubleshooting

   • For "70.14 CH2 COMLOSS", clean fiber interfaces and verify node address (70.15) .

4. Maintenance

   • Record address (70.15) before replacement; restore system software (*.BGP) to new modules .

5. Redundancy

   • Deploy dual units with "Master/Slave macro switch" for critical applications (e.g., grid control) .
