🧠 Technical function of modules 6FC9344 – 6FC9348 – 6FX2001 🧠

These modules perform essential functions within the automation architecture:

📡 Communication management between CNC and drives

🔌 Interfacing between SIMODRIVE modules and control systems

🔄 Real-time data exchange for motion control

🛠 Stabilization of machine information flow

🧩 Integration with peripherals and industrial networks

Without these modules, the control chain cannot function correctly, even if drives and CNC are fully operational.

📊 Functional differences between 6FC9344, 6FC9348 and 6FX2001 📊

Although they belong to the same application field, the three modules cover different roles:

👉 6FC9344 → interface module for connections between control unit and drives

👉 6FC9348 → advanced version for more complex architectures

👉 6FX2001 → communication module for data and signal integration

This structure enables the design of scalable modular architectures depending on plant complexity.

🏭 Main application sectors 🏭

Modules 6FC9344 / 6FC9348 / 6FX2001 are used in:

• CNC machine tools

• Multi-axis machining centers

• Automatic production lines

• Precision mechanical processing plants

• Industrial handling systems

In all these environments, communication stability between CNC and drive directly affects precision, safety and productivity.

⚠️ Production status and operational criticalities ⚠️

Like many components of the SIMODRIVE and SINUMERIK platforms, roots 6FC9344–9348–6FX2001 are now:

❌ Discontinued

❌ With limited direct manufacturer support

❌ Increasingly difficult to source on the traditional market

This leads to concrete risks:

• Complete machine shutdown even with functioning drives

• Long downtime while sourcing spare parts

• Loss of CNC–drive communication

• High costs for unplanned retrofit

✅ The value of E-Repair services for these modules ✅

E-Repair, an Approved Siemens Service Partner in Europe, supports these modules with:

🔧 Professional electronic repair

♻️ Full regeneration restored to “zero hours” condition

🧪 Functional testing on dedicated test benches

💾 Backup and verification of machine data

🚀 Advance replacement units to reduce plant downtime

The goal is to restore communication continuity without replacing entire CNC architectures.

🔍 Certified regenerated vs generic used 🔍

In the obsolete communication module market, it is essential to distinguish between:

• Used product → no real testing, no technical guarantee

• Refurbished product → partial intervention, no full overhaul

• E-Repair regenerated product →

  • Preventive replacement of wear-prone components

  • Complete technical cleaning

  • In-depth functional testing

  • Performance comparable to new

This drastically reduces the risk of communication loss, CNC errors and recurring machine downtime.

📈 Integration with predictive maintenance and MAAS 📈

If the company uses predictive maintenance systems, machine data allows to:

• Detect communication instability

• Identify intermittent network errors

• Activate targeted E-Repair interventions under the MAAS – Maintenance as a Service model

✅ Data originates from the plant
✅ Analysis generates the alert
✅ E-Repair operational response is immediate

🛑 Why intervene before failure 🛑

A degrading interface module can cause:

• Loss of CNC–drive communication

• Intermittent machine errors

• Complete plant shutdown

• Production scrap

• Sudden unplanned downtime

Intervening in advance means:

✅ Reducing plant downtime

✅ Protecting the entire CNC system

✅ Ensuring production continuity

✅ Optimizing maintenance costs

🧩 Conclusion 🧩

Roots 6FC9344, 6FC9348 and 6FX2001 represent a crucial link between CNC, drives and SIMODRIVE communication systems. Even though they are often discontinued today, they can continue to guarantee reliability, stability and productivity thanks to certified regeneration and an advanced MAAS model.

In industrial automation, production continuity also depends on the invisible stability of electronic communication.
