Siemens Broadens Sinamics G Line for Continuous‑Motion Applications
Why the Upgrade Matters
Machine builders and plant operators are under constant pressure to boost throughput, cut energy use, tighten security and shorten time‑to‑market. Siemens’ refreshed Sinamics G series answers these demands with a single, scalable drive platform that can be configured for a wide array of continuous‑motion tasks—ranging from high‑speed packaging lines to heavy‑duty extrusion plants.
Core Pillars of the New Generation
| Feature | What It Means for Users | Key Specification |
|---|---|---|
| Security‑by‑Design | Cyber‑risk is mitigated from the hardware level up, eliminating the need for retro‑fit security modules. | IEC 62443‑4‑2 Security Level 2 (SL 2) compliance; EU Cyber Resilience Act‑ready |
| Integrated Safety Functions | Safety logic is embedded, reducing external safety relays and simplifying SIL certification. | Safety Integrity Level 3 (SIL 3) for emergency stop, safe torque off, and safe speed monitoring |
| Digitalization & Transparency | Real‑time data is accessible via OPC UA, supporting condition monitoring, asset management and predictive maintenance. | Built‑in OPC UA server, web‑based diagnostics, TIA Portal seamless engineering |
Power & Performance Spectrum
The new Sinamics G family covers nine standard power classes (0.75 kW, 1.1 kW, 1.5 kW, 2.2 kW, 3.0 kW, 5.5 kW, 11 kW, 22 kW, 56 kW, 112 kW, 225 kW, 560 kW). Each class delivers:
- Peak torque up to 4 500 Nm (560 kW version)
- Speed range from 0 – 6 000 rpm (continuous)
- Efficiency up to 98 % (IE3/IE4 compliant)
These figures enable designers to select a single drive family for everything from light‑weight pick‑and‑place robots (≤ 2 kW) to large‑scale winding machines (≥ 225 kW), preserving a common engineering workflow.
Engineering Consistency via TIA Portal
All Sinamics G drives now ship with a TIA Portal‑native device description. Engineers can:
- Select the exact drive model from a unified catalog.
- Configure parameters, safety functions and network settings in a single project file.
- Commission the hardware using the integrated web server—no separate HMI required.
The unified approach shortens the engineering cycle by an estimated 20‑30 %, according to Siemens internal testing.
Data‑Driven Maintenance
The embedded OPC UA interface streams drive‑level metrics (current, temperature, vibration spectra) to MES or ERP systems. When paired with Siemens’ MindSphere analytics, users can:
- Detect bearing wear before failure (prediction horizon up to 1 000 h).
- Optimize energy consumption by identifying sub‑optimal torque profiles, yielding up to 5 % electricity savings in continuous‑run scenarios.
Comparison with the Previous Generation
| Attribute | Sinamics G (Legacy) | Sinamics G (Gen‑2) |
|---|---|---|
| Power Range | 0.75 kW – 225 kW | 0.75 kW – 560 kW |
| Safety Integration | Up to SIL 2 | Up to SIL 3 |
| Cybersecurity | IEC 62443‑4‑2 SL 1 (add‑on) | SL 2 built‑in, EU‑Act ready |
| OPC UA | Optional license | Native, no extra cost |
| TIA Portal | Separate device libraries | Unified, single‑project workflow |
| Efficiency | IE3 (≈ 96 %) | IE3/IE4 (up to 98 %) |
| Diagnostic UI | Basic web page | Full‑featured web server with dashboards |
What This Means for the Industry
- Reduced Development Time: Standardized safety and security blocks eliminate parallel certification tracks.
- Lower Total Cost of Ownership (TCO): Higher efficiency and predictive maintenance cut energy bills and unscheduled downtime.
- Future‑Proofing: Compliance with the upcoming EU Cyber Resilience Act protects investments against regulatory changes.
Bottom Line
Siemens’ refreshed Sinamics G series delivers a single, scalable drive platform that unifies safety, cybersecurity and digital connectivity for continuous‑motion machinery. By expanding power capacity to 560 kW, embedding SIL 3 safety and IEC 62443 SL 2 security, and offering out‑of‑the‑box OPC UA and TIA Portal integration, the new generation equips machine builders with the tools to accelerate development, slash operating costs and stay ahead of tightening regulatory demands. In short, the Sinamics G portfolio sets a new benchmark for performance‑driven, secure and data‑rich motion control.
