Why Engineers Specify This Model
- Ultra-compact booksize form factor – 30 mm width enables high-density multi-axis cabinets, reducing panel footprint by up to 40% vs. standalone drives.
- DRIVE-CLiQ daisy-chain topology – Single cable carries power, encoder feedback, and diagnostics, eliminating separate encoder wiring and simplifying commissioning.
- Shared DC bus architecture – Energy regenerated during deceleration is instantly reused by accelerating axes, cutting energy consumption in multi-axis systems.
- Integrated safety functions – STO (Safe Torque Off) and SS1 (Safe Stop 1) certified to SIL 2 / PLe without external safety relays.
- Seamless SIMOTION / SINUMERIK integration – Native isochronous PROFINET and DRIVE-CLiQ ensure deterministic cycle times ≤ 125 µs for servo-class performance.
- Scalable within S120 ecosystem – Mix and match with Line Modules, Control Units (CU320-2), and Sensor Modules without re-engineering the DC bus.
Complete System Bill of Materials
A fully operational SINAMICS S120 drive system based on this Motor Module typically requires:
- Line Module (Active/Smart/Basic) – e.g., 6SL3130-6AE21-0AB1 (Active Line Module, 16 kW) for DC bus supply and regenerative feedback.
- Control Unit – e.g., 6SL3040-1MA01-0AA0 (CU320-2 DP) or CU320-2 PN for centralized multi-axis control.
- DRIVE-CLiQ Hub Module – e.g., 6SL3055-0AA00-2AA0 (DMC20) for topology expansion.
- Sensor Module Cabinet (SMC) – e.g., 6SL3055-0AA00-5AA3 (SMC30) for TTL/HTL encoder evaluation.
- Braking Module & Resistor – Required if regenerative line module is not used.
- 24 V DC Power Supply – SITOP PSU100S or equivalent for control electronics.
- Motor with DRIVE-CLiQ interface – e.g., Siemens 1FK7 or 1FT7 servo motor series.

Application-Specific FAQ
Q: Can the 6SL3201-0BE21-0AA0 operate as a standalone drive without a CU320-2?
A: No. This Motor Module requires a SINAMICS S120 Control Unit (e.g., CU320-2 DP/PN or CU310-2) connected via DRIVE-CLiQ. It cannot operate independently.
Q: What motor types are compatible?
A: Synchronous servo motors (1FK7, 1FT7), asynchronous induction motors, and linear motors with appropriate encoder feedback. DRIVE-CLiQ-equipped motors enable automatic motor identification.
Q: Is this module suitable for safety-critical applications?
A: Yes. The integrated STO function is certified to SIL 2 / PLe, making it suitable for Category 3 safety architectures per EN ISO 13849-1 without additional external safety relays.
Q: What is the maximum cable length between the Motor Module and the motor?
A: Siemens specifies a maximum motor cable length of 50 m (shielded) for standard configurations. Longer runs require output reactors (e.g., 6SL3202-0AE21-0AA0).
Q: Can I mix this module with older SINAMICS S120 booksize modules on the same DC bus?
A: Yes, provided all modules share the same firmware generation and the Line Module is correctly sized for the total connected load. Consult the SINAMICS S120 System Manual (6SL3097-4AA00-0BP6) for bus sizing rules.
