ABB RDCO-02C Communication Board 

1. Product Description

The ABB RDCO-02C is a communication interface board primarily used in ABB’s ACS800 series variable frequency drives (VFDs). It facilitates high-speed data exchange between the drive and external control systems, supporting distributed drive control (DDCS) applications where multiple drives need synchronized operation, such as in paper machines, textile production, and multi-motor conveyor systems.

Key features include:

• DDCS (Distributed Drive Control System) compatibility for master-slave drive synchronization.

• Fiber-optic communication (CH2 channel supports master/slave mode).

• Rigid and flexible control modes (speed/torque control for load sharing).

• Hot-swappable design for easy maintenance.

2. Technical Specifications

3. Key Features & Advantages

✅ Master-Slave Synchronization

• Enables rigid coupling (host speed control + slave torque control) for load-sharing applications like paper machine sections3.

✅ Fiber-Optic Reliability

• Noise-immune communication for long-distance signal integrity.

✅ Plug-and-Play Installation

• Direct integration with ACS800 drives without external converters.

✅ Industrial Durability

• Designed for 24/7 operation in harsh environments.

4. Typical Applications

1. Paper & Textile Machinery

   • Synchronizes multiple drive sections for uniform tension control.

2. Conveyor Systems

   • Coordinates motor speeds in material handling lines.

3. Printing & Winding Machines

   • Ensures precise speed matching for web processing.

5. Configuration Notes

⚠ Parameter Setup

• 60.01 MASTER LINK MODE (set as MASTER or SLAVE).

• 60.07 MASTER SIGNAL2 (host speed reference).

• 60.08 MASTER SIGNAL3 (host torque reference).

⚠ Maintenance

• Use ABB-approved fiber cables (e.g., AIMA-01 adapter for I/O extensions).
