Siemens SINAMICS S120 Series Technical Notes

The Evolution of SINAMICS S120 Architecture

The SINAMICS S120 platform was introduced in the early 2000s as the successor to the SIMODRIVE 611 series, consolidating servo and vector drive functionality into a unified hardware and firmware ecosystem. Early S120 generations used DRIVE-CLiQ as the digital motor feedback interface — a proprietary protocol that eliminated analog encoder wiring and enabled automatic motor identification. The booksize format (6SL312x) was designed for cabinet-integrated multi-axis applications, while the chassis format (6SL3310/6SL3315) addressed high-power single-axis requirements.

Firmware evolution progressed through SINAMICS Startdrive (TIA Portal integration), replacing the legacy STARTER commissioning tool. Hardware revisions introduced higher switching frequencies, improved thermal management, and expanded Safety Integrated functions (STO, SS1, SLS, SDI) certified to SIL 2 / PLe. The 6SL3120 Double Motor Module family specifically addressed applications requiring two independent motor axes sharing a single DC bus connection, reducing cabinet footprint by approximately 30% versus two single-axis modules.

Compatibility constraints exist between hardware generations: CU320-2 Control Units require firmware ≥ V4.x, while older CU320 (without suffix) is limited to V2.x firmware. DRIVE-CLiQ topology rules restrict daisy-chain depth and total node count per port. Mixing booksize and chassis components on the same DC bus requires careful derating calculations per Siemens application note DT MC 2.

Sourcing Hard-to-Find & Obsolete SINAMICS S120 Parts

For plants operating legacy S120 configurations where a full drive system upgrade is not economically viable, DriveKNMS provides lifecycle extension support: verified replacement modules, cross-reference mapping to current-generation equivalents (e.g., mapping AA3 to AA4 hardware revisions), and documentation of firmware compatibility constraints to prevent commissioning errors during module swap.

Quality Control for the SINAMICS S120 Range

SINAMICS S120 Double Motor Modules present specific test challenges due to their dual-axis DRIVE-CLiQ backplane communication and shared DC bus architecture. DriveKNMS applies the following test protocol to all S120 booksize modules prior to dispatch:

• DC bus pre-charge circuit continuity and capacitor bank ESR measurement
• DRIVE-CLiQ port enumeration test using a CU320-2 reference Control Unit
• IGBT gate drive signal verification on both motor output channels under resistive load
• Safe Torque Off (STO) function test: activation via digital input and verification of output inhibit state
• Thermal imaging under 50% rated load for minimum 15 minutes to identify hot-spot anomalies on power semiconductors
• Firmware version readback and hardware revision logging for traceability documentation
