Selection Guide
Use the table below to select the correct Smart Line Module for your SINAMICS S120 Booksize system:
- ≤ 11 kW total axis power → 6SL3201-0BE21-8AA0 (18A) ✓ This model
- ≤ 22 kW total axis power → 6SL3201-0BE23-8AA0 (36A)
- ≤ 30 kW total axis power → 6SL3201-0BE25-0AA0 (50A)
- ≤ 55 kW total axis power → 6SL3201-0BE28-0AA0 (80A)
- Requires active harmonic filtering → Consider 6SL3210-1SE21-8AA0 (ALM)
Selection based on 400 V AC supply. Derate by ~10% at 480 V AC. Always add 20% headroom to total motor module power demand.

Replacement & Compatibility FAQ
Q: Can I replace 6SL3201-0BE21-8AA0 with a 6SL3130-6AE21-8AA0?
A: Functionally similar, but the 6SL3130 series uses an older hardware revision. Firmware and DRIVE-CLiQ compatibility must be verified with your Control Unit firmware version.
Q: Is the 6SL3201-0BE21-8AA0 compatible with SINAMICS S150?
A: No. The S120 Booksize Smart Line Module is designed exclusively for the S120 Booksize drive system. S150 uses its own integrated line module.
Q: What is the difference between a Smart Line Module (SLM) and an Active Line Module (ALM)?
A: The SLM (this model) provides basic regenerative feedback with lower harmonic distortion than a Basic Line Module. The ALM additionally provides active harmonic compensation and is required for stricter grid compliance (e.g., IEEE 519). The ALM equivalent is the 6SL3210-1SE21-8AA0.
Q: Can Konmask supply a tested used / refurbished unit?
A: Yes. Refurbished units with full test reports are available upon request at reduced lead time. Contact us for availability.
Q: What is the lead time for new stock?
A: Standard stock: 3–7 business days. Ex-factory orders: 4–8 weeks. Contact us for current availability.
