1. Parent Family: SIMODRIVE
🧩 Part of the broader Siemens SIMODRIVE architecture

The 6RB modules belong to the SIMODRIVE family, the Siemens platform for:

• Multi-axis drive systems

• Control of DC/AC motors

• Industrial rectifiers and power supplies

• Power management and DC bus control

The 6RB series represents the generation preceding the SIMODRIVE 611 modules, yet it remains compatible with many industrial systems that are still fully operational.

2. Function of the 6RB2000 – 6RB2012 – 6RB2025 Modules
⚡ Generation of the DC bus voltage

Conversion of the AC mains into a stable DC voltage required for the operation of the connected drives.

🔒 Stabilization of the power chain

Maintains constant DC voltage even under variable load conditions, ensuring supervision and operational continuity.

🛡 Plant protection

Protection against overvoltage, overload, overheating, and abnormal power conditions.

3. Main Differences Between the 6RB Series Models

This diversification makes it possible to configure highly different plants in a modular way, while consistently maintaining the SIMODRIVE ecosystem.

4. Why do many plants still use the 6RB series?

🧱 Long-term reliability
These modules are designed to operate for decades, even in harsh industrial environments.

♻️ Perfect integration with legacy machines
They are compatible with many production lines built in the 1980s and 1990s that remain fully operational today.

💰 Revamping often unnecessary or very costly
Upgrading a SIMODRIVE system requires interventions on:

• drives and power modules

• PLCs and machine logic

• CNC software

• wiring and certifications

Regeneration solves the issue without altering the existing architecture.
